Hi! I am looking to upgrade my current sales dashboard. I am looking for a Data Specialist who I can learn from and who can propose...from CSV files. I need a place where I can import that data to. I would like the dashboard to be as detailed as possible showing multiple KPIs, graphs, and correlations between the various data. Once setup, I would like it to be fairly simple to import new data, and modify the dashboard as needed over time. I would like this setup to be fully offline and local. My current thoughts are Metabase + SQLite. However I am open to other solutions and recommendations. I will be able to provide an example of the CSV during discussion to see how and what we can achieve with the data. I am looking for an individual who I can work with long term as my Data S...

I want a lean, dependable Android app that helps me log day-to-day sales without any bells and whistles. The flow is fixed at four material-designed screens: 1. Company creation 2. Product creation 3. Sales / POS entry 4. Report & Export Everything may live in a local SQLite (or similarly lightweight) database so figures stay put between sessions. Jetpack libraries are welcome if they speed things up. Deliverables I expect • Complete Android Studio project with tidy, well-commented code • Signed APK that installs on Android 9+ • Short README describing how to build, where the data sits, and how to trigger the CSV/email export If the compiled APK mirrors the four-step flow above, stores data reliably, and can push out a CSV or email attachment of ...

I need an experienced Python trading-bot developer to optimize and refactor a live async trading bot connected to REST & WebSocket APIs, which currently slows under load and misses ticks/orders. The task includes profiling bottlenecks, improving async/WebSocket performance, optimizing pandas & SQLite usage, and ensuring real-time execution. Goal: <200 ms tick-to-order latency, zero missed ticks, clean refactored code, tests, and one-command VPS setup.

...Desktop side must run on Windows at minimum; cross-platform (Electron, .NET MAUI, or similar) would be a bonus. • Clean, intuitive UI with charts, trend lines, and colour-coded alerts. • Ability to push configuration commands back to the devices—for example, change sampling frequency or trigger a fan/ventilation relay if air quality drops below a set level. • Data should be persisted locally (SQLite or LiteDB is fine) and optionally mirrored to the cloud for remote access. Deliverables 1. Fully commented source code for both the firmware (if you supply sample sensor firmware), cloud or broker layer, and the desktop application. 2. Build/run instructions and an installable desktop package. 3. A short write-up describing how to extend the system ...

...present the project from a single, self-contained workspace (code, data and notebook if needed). Tech notes AI Studio can host standard web stacks, so feel free to work in React, Vue, plain Django templates, or another lightweight framework—just keep dependencies reasonable so the environment launches quickly. Client-side state management is fine, but server-side persistence (even a simple SQLite or JSON store) is required so the demo survives a page refresh. Deliverables 1. Complete source code with clear folder structure. 2. AI Studio project file / workspace export ready to import. 3. A short README that explains how to start the app, add new products and change colours or sizes. 4. One-click (or single command) launch script so my tutor can evaluate with...

...slows, misses price ticks and occasionally skips orders, so I need a clean performance tune-up and code review. Your task is to comb through the existing modules—order manager, data streamer, and strategy loop—identify the bottlenecks, then fix or refactor as needed so the bot reacts in real time without dropping trades. Expect to work with async I/O, websockets, pandas dataframes and a small SQLite trade log. Deliverables • Refactored, well-commented Python code with any slow sections profiled and optimised • A brief report that explains each change, shows before/after latency benchmarks, and lists test results on both sandbox and live endpoints • Updated and a one-command setup script so I can spin the bot up on a fresh VPS Acceptance ...

...through past days. I also want the raw JSON/CSV available for export so I can feed it to our internal BI dashboards later. Technical expectations • Android Studio / Kotlin (or Java if you strongly prefer) with the latest Google Maps SDK and fused-location provider. • Accurate, low-drain background location tracking that still complies with modern Android permissions. • Local database (Room or SQLite) for offline storage; sync hooks ready for a REST endpoint we’ll supply. • Source code in a private Git repo, plus a signed APK for testing. Acceptance criteria 1. Distance total matches Google Maps straight-line calculations within ±2 %. 2. Meeting Point arrival is detected within a 25 m radius. 3. App remains responsive after 8 h of...

...and generate simple reports or CSV exports without ever leaving the interface. A clean, intuitive UI is important because I expect non-technical staff to use it daily. Under the hood, I’m open to the stack you feel is most stable—C#/.NET (WinForms or WPF) or a lightweight Electron build are both fine as long as startup time is fast and the installer is straightforward. Local storage can sit in SQLite or a small embedded SQL Server database; just make sure the data file is easy for me to back up. I’ll provide the exact field list and sample data once we start, but anticipate roughly 15–20 columns, a few dropdowns, and one attachment field per record. All code must be well-commented, and I’d like a brief hand-off call or screen-share at the end so I ...

I need the pin-to-keep behaviour added to my existing Android text-clip list. A user should be able to touch-and-hold any text clip in the RecyclerView; that gesture toggles a “pinned” state. Pinned clips remain in the local Room/SQLite store indefinitely, while every unpinned clip should be purged exactly one hour after its creation time. I’m fine with the standard Android UI conventions—think long-press selection, a pin icon in the contextual action bar, and a small pinned indicator inside each row. No custom assets are required beyond the built-in Material icons. The current codebase is Kotlin, minSdk 24, using ViewModel + LiveData. Please stay within that stack. If you see a cleaner Jetpack-recommended way to schedule the one-hour expiry (WorkManager or...

Hello folks, I developed a desktop application a few weeks ago. It includes a SQLite database, allows users to search using queries, and can export results to a Word document. It’s a fairly simple search app. However, I now need to update the database and rebuild the application. I can do this myself, but the problem is that other team members don’t know how to update the database or rebuild the app. So I have two ideas: 1. Modify the application so users can drag and drop the database file each time. This way, they wouldn’t need to rebuild the app whenever the database is updated, but they would always need access to the database file. 2. Create an automated solution that updates the database and rebuilds the desktop application with a single click. I&rsquo...

Our ALFRED capstone project is almost feature-complete: the JavaFX desktop UI is in place, the core algorithm runs in Python, and an SQLite file stores everything. The weak link is the layer that moves data smoothly between these pieces. I will hand over: • the ERD and all schema scripts • the current DAO / repository classes in Java • the Python modules that read-write through sqlite3 • a short workflow document that maps every UI action to its expected database touchpoints Your mission is to tighten that pipeline. Make the UI’s requests reach the Python logic, make the logic persist results without race conditions, and return fresh data to the interface instantly. Along the way, refine any clumsy statements—sub-queries, joins, or missi...

I need a forensic specialist ideally based in Ho Chi Minh City to pull every scrap of data still living inside Zalo’s local SQLite stores on a Windows laptop. The focus is narrow and clear: recover all text messages plus any contact information linked to those chats; photos, videos, and other media can be ignored for now. You’re free to work with Magnet AXIOM, Cellebrite, Autopsy, X-Ways, or your own Python / sqlite3 scripts—whatever lets you prove the chain of custody and export clean, searchable tables. Deliverables • CSV or XLSX of every recovered message with timestamp, sender/receiver IDs, and thread reference • CSV or XLSX of the full contact list (UID, display name, phone/email where available) • A brief but reproducible methodology r...

Everything runs locally on Windows so performance is critical even when the network is down. A clean WPF or WinForms front-end connected to a lightweight SQL (SQLite or SQL Server Express) back-end would work well, but I’m open to your preferred Windows-friendly tech stack as long as the UI stays snappy and the database is easy to back up. Acceptance will be based on: 1. Installer (.exe or MSI) plus complete, well-commented source code. 2. Role-based log-in (storekeeper, technician, inspector, finance) with simple permis...

A streamlined WhatsApp chat solution written in Python is the goal. The code will live on my Ubuntu 22.04 VPS and must let me programmatically send, receive, and log WhatsApp messages from an existing Business account. Reliability comes first; every outbound message needs an acknowledgement callback and every inbound message should be captured in a local SQLite or PostgreSQL table for later reporting. Scope highlights • Clean Python 3.x code that wraps the official WhatsApp Business Cloud API (or another compliant gateway if you can justify it) • Simple CLI or minimal Flask/FastAPI endpoint to trigger messages with parameters: recipient, template/body, media (optional) • Webhook listener that records incoming messages, delivery receipts, and errors to the datab...
