I need an experienced deskside technician I can call in on a per-day basis to cover three locations: Pekan and Puchong in Malaysia, and Singapore. When you are on site, you’ll be the second line of support for anything that lands on the user’s desk: • Diagnose and repair PCs, laptops, printers and other client-side hardware • Install, configure and patch Windows applications as well as in-house software • Restore or improve network connectivity at the desktop, tracing issues back to the switch if required We keep a full set of tools, spare parts and imaging gear on each site, so you will not be expected to bring your own kit—just your know-how and a positive attitude. Because much of the troubleshooting touches switching and cabling, I’m...

I run a small UniFi network that serves a local WebRTC page hosted on our own server. The page opens instantly on my laptop, yet my iPads refuse to load it at all—even though they are on the same Wi-Fi. Alongside that, Wi-Fi quality on the iPads swings from excellent to poor for no clear reason. The site must be reachable this weekend, during European daytime hours, so I need a UniFi-savvy network admin who can jump in promptly, review the configuration, and correct whatever is blocking traffic to the tablets. Context you’ll step into • Current issue: the iPad shows “page not loading at all.” • VLAN status: I’m not sure the settings fully cover the iPads. • Hardware in play: – UniFi Access Points – UniFi Switches ...

Fix LinkedIn Access Error Project Details ₹600.00 – 1,500.00 INR Bidding ends in 6 days, 23 hours On my Windows laptop LinkedIn never loads in my main browser and instead throws “This site can’t be reached … ERR_ADDRESS_INVALID” plus a “connection not secure” warning. What makes this stranger is that the same laptop opens LinkedIn perfectly in another browser, so the problem is isolated to one browser or a related system setting. Here is what I have already ruled out: * I tested on a different Wi-Fi network and still saw the same “can’t be reached” page. * I cleared the browser’s cache and cookies—no change. * Tutorials on YouTube, ChatGPT, Bard, and assorted blogs have not helped. I need an expert who can quic...

Our small office in Edmonton has been struggling with intermittent connectivity on a few workstations. The ISP link and router appear fine, so we suspect a local issue—possibly the cabling runs, the docking stations, or another piece of hardware we have not yet identified. I need someone who can come on-site, isolate the fault, and restore a rock-solid connection the same day if possible. You should arrive ready to test cabling (Cat-5e/Cat-6), swap or re-terminate ends, check docking-station throughput, and verify switch ports with your own tools (Fluke tester, multimeter, laptop, etc.). Once the root cause is found, I’ll need you to implement a fix or advise on any replacement parts and install them on the spot if feasible. Deliverables • Stable, consistently working ...

I need a reliable end-to-end VPN tunnel that lets me reach my home network safely whenever I’m on the road. The plan is straightforward: host a VPN server at my house and have a small travel router automatically connect to it, so every desktop, laptop, or phone I plug into that router behaves as though it’s on my local LAN. My devices • Desktops / laptops and mobile phones • Operating systems in play: Windows, macOS, and Android Primary goal Secure remote access to my home network so all my internet traffic has my home IP address. Additionally, access to smart-home gear without exposing anything publicly. What I need from you 1. Recommend and configure the best protocol for this use case (WireGuard or OpenVPN are fine if they suit the gear). 2. Set up t...

My team manages a mid-sized data center that runs almost entirely on Cisco switches, routers, and firewalls. I need an experienced network engineer to jump in on a contract basis and keep everything running smoothly. Day-to-day work revolves around classic routing & switching tasks—think VLAN design, trunking, OSPF and basic BGP tuning, plus the inevitable “why can’t that server talk to that subnet?” moments. The core stack is Cisco IOS/IOS-XE with a mix of Catalyst and ISR hardware. Because this installation underpins production workloads, fast-paced troubleshooting is as important as clean architecture. You should be fully at home with TCP/IP and the OSI model, comfortable tracing packets through multiple hops, and ready to document changes clearly for hand...

Environment details and access methods (SSH, Ansible, GitLab) will ...

My private server farm runs entirely on Windows Server 2019/2022 and I want a single, reliable point of contact to keep it both secure and resilient. Day-to-day, you will be hardening the network with advanced threat-detection practices—think real-time log analysis, strict firewall policy reviews, prompt patching, and well-documented incident response plans. All data protection flows through Veeam. I rely on daily image-level backups, off-site replication, and periodic restore tests, so you’ll need to stay on top of job success reports, storage consumption, and any failure remediation without waiting for me to ask. Support is part of the arrangement: when an issue or change request lands in the ticket queue, I expect timely follow-through and clear communication until closure...

I need an end-to-end, sub-second analytics pipeline that streams market data from stock-exchange feeds through Kafka, processes it with Spark Structured Streaming, stores it in TimescaleDB, and exposes real-time forecasts via a FastAPI service. The modelling workflow must be fully tracked in MLflow so every experiment, metric, and artifact is reproducible. Data sources are push-first wherever the provider allows; any remaining economic indicators can be polled on a schedule. Live market data from stock exchanges is the non-negotiable core feed, with news and macro releases treated as optional extensions once the baseline is rock-solid. You will design the Kafka topics, Spark jobs, Timescale hypertable schema, and the FastAPI endpoints that deliver the latest forecast and confidence bands...

I want to roll out PacketFence across several offices and datacentres and need it designed, installed, and fully tested so our users and devices can connect seamlessly and securely. High availability is mandatory, so the build should include redundant nodes and database replication that can survive a full-site outage without losing service. Authentication & authorisation • Our primary user flow is SAML with MS Entra ID; staff should hit the captive portal, bounce to Entra for login, and come back with the right role and VLAN automatically assigned. • Device compliance has to plug into both Intune and Lansweeper so non-compliant machines are quarantined or dropped into a remediation VLAN immediately. • IoT devices and printers will authenticate by MAC address today...

I’m spinning up a brand-new AWS environment and want it built right the first time. The core stack must include secure EC2 instances running a database server workload, S3 buckets for object storage, and at least one RDS database instance. This deployment will host banking-related data, so tight network segmentation, encryption at rest and in transit, and granular IAM policies are mandatory. My preference is to have everything created with infrastructure-as-code (CloudFormation or Terraform) to keep future changes controlled and auditable, but I’m open to your recommended tooling if it speeds delivery without sacrificing reliability. Deliverables • VPC design and implementation with public/private subnets, route tables, NAT, and security groups suitable for a production ...

My current web workload sits entirely on EC2 and I’m paying more each month while response times keep slipping. I want fresh eyes on the stack, so the engagement begins with a deep-dive audit: CPU, memory, database behaviour and network flow. Please capture every finding in a detailed, evidence-based report—graphs, screenshots, CloudWatch metrics, the works—so decisions are backed by data, not guesswork. Once the pain points are clear, I’ll need a redesign that balances cost and performance. Feel free to compare alternatives such as Lightsail or a move to managed services, but assume EC2 remains the baseline. The proposal should include an architecture diagram, projected monthly spend, and clear justification for each component. If we proceed to implementation, ...
