I need a script that visits the California State License Board site, drills down into every contractor record, and captures every publicly visible field—license number, classifications, bonding, personnel, status history, contact info, everything. The scraper must handle pagination, search-form quirks, and any soft-rate limiting the site imposes so the run finishes without manual stops or captchas blocking the flow. Once gathered, the data should be written to a single CSV file, overwriting the previous file on each run so I always have a fresh snapshot. The entire process has to trigger automatically every 24 hours (cron, systemd timer, Cloud Scheduler—whatever you prefer) and run headless on a Linux VPS I’ll provide. I am fine with Python (requests, BeautifulSoup, Sc...

I have a stack of AWS Cloud Practitioner e-learning modules that must be finished and verified before tomorrow’s academic deadline. If you already know the AWS basics you should be able to power through the videos, quizzes, and knowledge checks quickly. Here’s the workflow: I’ll share portal access, you work through every assigned unit, and you send regular chat updates so I can monitor progress. Once everything shows 100 % complete, capture clear screenshots of each finished section as well as the final dashboard, download the auto-generated certificates, and forward them to me. Those screenshots and certificates are the only proof I need for submission, so please keep them organised. Ideal fit: an engineering or IT student—especially if you’re in Bangalore...

This is a focused 1-day task. The LLM pipeline already exists in Python — I need it containerized with Docker and running live on AWS by end of day. No research, no exploration — come ready to execute. Deliverables: 1. Dockerfile & Docker Compose Write a production-grade Dockerfile for the LLM inference pipeline. Multi-stage if needed, minimal image size, env vars for config and secrets. 2. AWS deployment Deploy the container to AWS (ECS Fargate preferred, or EC2 if GPU required). Expose a working endpoint. Basic IAM role and security group setup. 3. Smoke test + handoff Confirm the endpoint is live and responding. Provide a short Bash script or README so I can redeploy independently. No undocumented magic. YOU'RE A FIT IF: ✔️ You've deployed a containerized ...

I’m kicking off a six-month data-centre upgrade in Frankfurt and need a senior (Level 3-4) technician who can step in as the on-site networking authority from day one. The work is hands-on: racking and stacking new gear, bringing links online, fine-tuning routing and VLANs, then keeping a constant eye on performance once everything is live. You’ll spend the bulk of your time inside the data centre, so confidence working around live production cabinets, structured cabling and change-control windows is essential. The environment leans heavily on Cisco, HP Networking and a growing footprint of Arista switches; if you can move comfortably between those CLIs and their respective management suites, you’ll fit right in. Key outcomes I expect: • Clean installation of new h...

I need a command-line application that runs on a Raspberry Pi Zero 2 W and records audio when triggered by environmental sound. The tool needs to listen continuously and trigger a recording when it detects sound over a pre-specified frequency and amplitude. Recordings also need to include a buffer *before* the trigger event. So point by point, the tool needs to: – sample continuously while consuming minimal power, using 384 kHz as the default sampling rate – watch incoming samples in real time, trigger when both a user-defined frequency band and amplitude threshold are exceeded, including a pre-event buffer so the beginning of the sound is not lost – continue recording for a configurable post-trigger period, or until a maximum file length is reached – save...

I need my existing LibreNMS instance tuned so it reliably discovers, polls, and alerts on everything in my environment. The focus is on two areas: complete device + service monitoring and preparing LibreNMS to talk cleanly with other tools down the road. Here is what I expect: • Routers and switches: automatic discovery, interface-level statistics, error counters, traffic graphs, alert rules for outages or threshold breaches. • Linux & Windows servers: CPU, RAM, disk, process and service checks with meaningful, noise-free alerts. • A growing fleet of IoT devices: lightweight polling profiles that minimise resource usage yet still raise alarms when something goes offline or drifts out of spec. • Integration groundwork: enable and test the API, webhook and aler...

I’m building a Ground Control Station in C++ dedicated to a surveillance-grade quadcopter and I’d like your help finishing the core application. The immediate requirement is solid, low-latency GPS tracking: the program must read MAVLink telemetry from the vehicle, parse position data in real time, and display the aircraft on an interactive map (OpenStreetMap or similar). While the current focus is GPS tracking, I’m structuring the code so we can layer in real-time video or full mission-planning later, so clean, modular design matters. I’m working on Windows and Linux, so Qt or another cross-platform toolkit is preferred, but if you have a better library choice I’m open to it. Deliverables • C++ source and a cross-platform build script • Execu...

My current RPsignage deployment runs on Linux and I want to extend it with two purpose-built modules. Housing-Society Visitor Entry This add-on must let gate staff start a video call to the resident, wait for an accept/reject decision, register the visitor’s IN and OUT times, and push immediate notifications to the flat owner or tenant. The flow has to feel seamless on both the kiosk screen and the resident’s phone or browser. Salon & Doctor Appointment Booking Through a separate sub-domain, customers should be able to reserve a slot, see a live queue number, and watch the average wait time update in real-time on the web page until they are called in. The back-office view should let staff open/close slots, mark patients or clients as served, and analyse traffic trends...

I need to move a large group of pages to new URLs and preserve all SEO value with proper 301 (permanent) redirects. At this stage I do not yet have a complete mapping, so I will rely on you to audit the site, identify every outdated link, and pair it with its new destination before putting the redirects in place. PAGES CAN BE SEEN HERE Most of the work will sit in two phases: • Discovery & mapping – crawl the site (Screaming Frog, Sitebulb, or a similar tool), export every legacy URL, match it to its new location, and flag anything that has no clear equivalent so I can decide what to do. • Deployment & testing – once the mapping is approved, write the redirect rules in the most appropriate layer for the stack (.htaccess or NGINX config are both fine), p...

I’m organising a practical training block for a small group of intermediate-level engineers who work on Linux every day. They already know the very basics of Git, but they need to become confident with real-world workflows and a full CI/CD pipeline. The sessions must be fully hands-on: screen-sharing, live commands, quick coding exercises and immediate feedback rather than slide decks. We’ll spin up our own repos and pipelines so everyone leaves with muscle memory, not just notes. Core topics I want you to cover • Version control in GitHub: project setup, protected branches, pull-request etiquette • GitLab CI/CD: pipeline creation, runner configuration, environment variables, artefact handling • Git fundamentals in depth: merge vs rebase, pull/commit logi...

Our real-time data platform needs a rock-solid proxy layer that can move huge volumes of HTTP and SOCKS5 traffic with minimal latency. The immediate focus is designing and automating a high-concurrency architecture—from the Squid clusters themselves to the surrounding network and IP allocation logic—so that new nodes come online in seconds and stay performant under sustained load. Key components of the engagement • A web-based proxy panel that provisions, monitors, and rotates IPs automatically, exposing a clean API for our backend services. • Fully scripted Squid deployments on Linux, container-ready (Docker) but not container-bound, with Redis or similar caching where it measurably improves throughput. • Traffic distribution and fail-over policies tuned ...

We need terraform code to be updated to enable https traffic for ingress and egress at app gateway, firewall, AKS cluster ingress

I have a set of containerised microservices that must run smoothly on an AWS EC2 instance in the US East (N. Virginia) region. All services are already Docker-ised; what I need now is a production-ready deployment that can be reproduced easily. Here is the scope in plain terms: • Provision or harden an EC2 host, configure security groups and key-based access, then install and tune Docker (and Docker Compose if you prefer managing the stack that way). • Pull my private images from Docker Hub, wire them together, and expose the necessary ports through an Nginx or ALB front end so each microservice is reachable behind a single public endpoint. • Connect every service to a MySQL instance (RDS or on-host, whichever you recommend) and verify that environment variables, migrati...

I need a seasoned VoIP specialist to take my deployment from zero to fully operational. I will not be supplying configuration files, trunks, numbers, or even the initial account—everything has to be sourced, built, and verified by you. The finished system must speak SIP end-to-end so that soft-phones, desk phones, or mobile clients can register and place calls immediately after hand-over. I expect you to: • Create or configure the account, secure it, and document all access credentials. • Provision at least one SIP trunk or equivalent solution so the platform can dial in and out of the public network. • Set up a clean dial plan with working inbound and outbound routes and test calls in both directions. • Provide two sample SIP extensions (one desktop, on...

I need a working U.S.–based SIP trunk that plugs straight into my existing 3CX PBX, and I need it online immediately. This is for a live business system, so downtime is not an option. Here’s what I am expecting from you: • Provide a fully-provisioned SIP route (inbound and outbound) that registers successfully with 3CX and passes test calls. • Supply clear configuration details—host, authentication, codecs supported, 911 compliance, and any DID options—so I can import them quickly. • Hand over written step-by-step instructions or a short screen-share session for final cut-over. Please respond only if you can deliver right away. Include a detailed proposal outlining the solution you will supply, how you will integrate with 3CX, and your est...

I’m turning my scripted Minecraft world, Yeti SMP, into an experience that feels just like Unstable SMP, and I need a developer (or small team) who can take full ownership of the server side of things. The build starts with provisioning and running a rock-solid Java server, then layering in every feature that makes Unstable so much fun: • Custom plugins tailored for our lore-driven events • Hardened security to keep griefers and exploits out • Robust user-management tools so my content creators can focus on recording rather than policing players On the admin side I rely heavily on: • World-editing tools (FastAsyncWorldEdit, VoxelSniper or similar) for quick set builds • Fine-grained permission management (LuckPerms level control) • Real-...

I have just provisioned a fresh Linux-based VPS that runs Apache and I need my existing website—files, database, and all configuration—moved over seamlessly. Your task is to replicate the current production environment on the new server, point the domain once everything checks out, and make sure the site is fully functional after the switch. Here is what I expect to receive at the end of the engagement: • All site files copied to the VPS with correct ownership and permissions • Database exported, imported, and linked to the application • Apache virtual host configured, SSL certificates (if any) reinstated, and relevant PHP modules enabled • Any hard-coded paths or connection strings updated • A brief hand-off note outlining what you change...

Since the latest round of software updates on my Linux server running cPanel/WHM, Exim has stopped sending any mail at all. Messages queue but never leave the server, so clients receive nothing and there are no corresponding bounces. I need an experienced cPanel administrator who can: • Trace the root cause inside Exim, whether it’s a mis-applied update, permission problem, broken ACL, or a service conflict. • Restore normal outbound delivery and confirm mail flows cleanly to external providers (Gmail, Outlook, Yahoo, etc.). • Document every change you make so I can reproduce the fix if I roll this server back or clone it. Access available: WHM, SSH, and cPanel account level if required. Minimal downtime is important, so please outline any service restarts y...

I need a reliable freelancer to help me acquire and configure a server dedicated to email newsletter campaigns. My monthly volume will sit somewhere between 10,000 and 100,000 messages, so the hardware and network resources must comfortably support that load without throttling or reputation issues. Your first task is to recommend the most cost-effective VPS or dedicated provider, walk me through the purchase, and then handle the full configuration. Gammadyne Mailer must arrive pre-installed, licensed, and ready for immediate use, with all required ports, DNS records, SPF, DKIM, and DMARC properly set. I’ll rely on you to fine-tune the MTA so our newsletters land in the inbox rather than the spam folder, and to provide a quick hand-off document that shows how to scale or warm additio...

I need a Postfix-based mailserver configured so our team can reliably send and receive email. Security is paramount, so the build must include SMTP AUTH, TLS/SSL, and STARTTLS throughout. Mailboxes will be accessed over IMAP only; no POP3 is required. Here is what I expect: • Install and configure Postfix on a Linux host of my choosing. • Enable and verify SMTP AUTH, TLS/SSL, and STARTTLS for all connections. • Integrate an IMAP service (such as Dovecot) and align it with the Postfix user database. • Harden the server with sensible defaults—SPF, DKIM, basic rate-limiting, and anti-relay measures. • Provide concise documentation that shows key config files, how to add new domains/users, and how to back up the settings. I’ll supply root or sudo ...

I’m ready to get and off GoDaddy and living on Cloudflare Pages as fast, maintenance-light static sites. While we do that, I also want every mailbox currently tied to GoDaddy moved over to Zoho Mail so I’m no longer paying the premium rates. What I need from you right now • Export the existing sites and rebuild them as static assets suitable for Cloudflare Pages. • Configure the repositories, build settings, and custom domains inside Cloudflare so traffic switches seamlessly once DNS is cut over. • Transfer DNS and nameservers away from GoDaddy without downtime. • Set up Zoho Mail for all existing addresses, create any required DKIM/SPF/DMARC records, and verify deliverability. • Document the process so I can trace what was changed and why....

I’ve just finished moving my site to a new host and now need the domain traffic switched over smoothly. I already have full access to the DNS management console, so you can dive straight in once we agree on the exact records to touch. Your task is to identify every entry that must change—most likely the root A record and the www CNAME—and update them so the domain resolves to the new server. I’d like the cut-over handled with minimal downtime, which means adjusting TTLs, scheduling the update at a quiet time, and confirming propagation once the edits are saved. Please double-check that SSL, email, and any sub-domains continue to work afterward. Deliverables • Updated zone file pointing to the new host • Brief confirmation report listing the records...

I have a PHP-based website that suddenly stopped talking to its MySQL database. Every page that relies on data now throws a connection error, so visitors see nothing but an ugly message. The rest of the codebase is stable; it’s purely the database hand-shake that’s broken. Your task is to dive into the existing PHP, identify why the connection fails, and deliver a clean, working fix. Once repaired, the site should load data normally without warnings or deprecated notices, and your solution must stay compatible with the current server stack (PHP 7.4 on Apache, MySQL 5.7). Deliverables • Updated PHP file(s) with the corrected connection logic • A short note outlining the root cause and the exact change made so I can maintain it later I can provide SSH or cP...

I want to run marketing campaigns from my own infrastructure rather than relying on third-party mailers, so I need a fresh Amazon SES (SMTP) environment built from scratch. I do not yet have an AWS account, so the first step will be guiding me through account creation, basic security hardening, and verifying my identity with Amazon. Once the account is active, I will rely on you to move the domain into SES, set up SPF, DKIM, and DMARC records, request production access, and secure the SMTP credentials. Please handle every configuration step necessary so I can plug the final host, port, username, and password directly into my email automation tool and start sending marketing emails without landing in spam. Deliverables will be straightforward: • A brand-new AWS account ready for bill...

I need to mirror our entire Python-based intranet that is still sitting on its original host, then refactor it with the help of Claude or Codex so it is easier to maintain and extend. The work starts with programmatically harvesting every layer of the running site—pages, APIs, and any hidden endpoints—and reconstructing the full stack in a local sandbox. Once everything is safely pulled down, the goal is to modernise the codebase and introduce AI-assisted capabilities while keeping day-to-day use strictly internal to our staff. Your first milestone will be a clean, verifiable extraction of: • Source code • Backend database • System configurations After that, I’ll lean on your Python expertise (BeautifulSoup, Requests, Selenium or similar) plus dire...

I need a reliable, easy-to-run script that can push out a large volume of emails through my own SMTP server. The goal is simple: feed the script a list of recipients, some HTML or plain-text content, hit run, and watch the messages go out without choking on size or volume limits. Key points you should know • The SMTP credentials are ready; no Gmail or Outlook APIs involved. • Speed matters—I’d like a working, test-passed version as soon as possible. • Language is up to you. Python, Node, or another mainstream option is fine as long as the final command is straightforward and the dependencies are minimal. What I need from you – A script that connects to my custom SMTP server, authenticates, and sends to a list pulled from a CSV or simple text file....

I run several Python scripts that pass data back and forth by writing to and reading from shared files. Everything works function-wise, but there’s a lag: values written by one script are not picked up quickly enough by the others, and the whole workflow stalls for a few seconds each cycle. I need that delay eliminated (or at least reduced to milliseconds). Your job is to pinpoint why the hand-off is slow—whether it’s file-system latency, missing flushes, locking logic, or anything else—and then adjust the code or workflow so each script sees the latest data almost immediately. A clean, well-commented solution is essential; I also want a brief note explaining what you changed so I can maintain it going forward. If you’re comfortable diagnosing synchronizatio...
