Software Engineering Jobs

I need a lightweight proof-of-concept that demonstrates an end-to-end OAuth 2.0 flow against a real healthcare EMR, then uses the granted token to call the FHIR Patient endpoint. The aim is simple: confirm that system-to-system (backend) credentials can be exchanged for an access token and that—with that token—I can reliably pull a single Patient resource when I supply either the patient’s MRN or their ID. Here is how I picture the work: • Implement the OAuth 2.0 client IN GO using the EMR vendor’s documented authorization-code or client-credentials flow (whichever the API allows for backend access). • Once authenticated, call the FHIR /Patient search endpoint twice—first filtering by identifier type “MRN”, then by the native “ID&...

I need a small Windows desktop utility that automatically pulls plain-text data from a single, password-free website and saves it locally. The program should launch with a simple GUI: a field where I enter the target URL, a “Start” button, and a progress indicator. Behind the scenes it must crawl only the pages I specify, respect , and return just the text — no images or binary files. I’d like clean, readable source code (C#, Python with PySide or another Windows-friendly language is fine) and a compiled executable that runs on Windows 10/11 without additional setup. At the end I should be able to: • Point the tool at the site • Click “Start” • Receive the extracted text in a single file stored in the same folder as the app (you can ...

I’m building a net-new Salesforce application and need an APEX developer who can take it from concept to deployment. The core objective is to stand up a custom solution—not tweak standard objects—so strong experience writing scalable APEX classes, triggers, and Lightning components is essential. Here’s what I’m after: • Automated workflows – We’ll start by mapping the business processes together, then you’ll translate them into Flow or APEX-driven automations that run reliably at scale. • Custom user interfaces – Expect to design and code responsive Lightning pages/components that make the UX intuitive for end users. • Oracle API integration – The app must push and pull data to an existing Oracle system via RE...

I am ready to turn a thoroughly back-tested momentum strategy into a production-grade, fully automated trading app. Over the last several years I have validated the rules on two to three years of historical data and now need a developer who can translate that logic into clean, efficient code, connect it to Dhan’s API, and let it execute live orders on Indian stocks and the Nifty index without manual intervention. The core flow is straightforward: ingest live market data, generate signals exactly as my tested rules specify, size positions according to available capital and risk limits, send orders to Dhan in real time, and monitor open trades until exit conditions trigger. Robust logging, error handling, and a simple dashboard or CLI summary of current positions and P&L will he...

I’m building a low-level control layer in C, talking to PostgreSQL exclusively through libpq. The goal is to let me steer the database in real time—core by core, megabyte by megabyte, and user by user—without relying on pgAdmin, psql scripts, or any third-party orchestration tool. Functional scope • Core-wise processing: I want to pin heavy jobs to specific CPU cores from the client side, exposing an API call where I pass a core map and the session adjusts `SET max_parallel_workers_per_gather`, `cpu_tuple_cost`, or similar parameters on the fly. • RAM-wise resource allocation: Memory ceilings should be adjustable per connection so I can bump or throttle `work_mem`, `shared_buffers`, or temp file limits dynamically. • User-wise messaging queues: Each ...

I have an existing codebase that works but still feels unfinished. What I need right now is a programmer who can jump in, understand the current architecture quickly, and add the new features I have mapped out. This is purely an enhancement job—no ground-up rebuilds or cosmetic tweaks—so you should be comfortable reading someone else’s logic, spotting extension points, and implementing clean, maintainable solutions that blend seamlessly with what is already there. Once we agree on the priorities, I will share the repository, a concise roadmap of the desired functionality, and any relevant API keys or design docs. I am open to whichever stack management tools you prefer (Git, GitHub, GitLab, Bitbucket) as long as your commits are well-commented and each feature is deliv...

I need a small C++ application that feeds keystrokes to Spiritvale even when the game window is minimised or running in the background, so I can work on my PC while the macro keeps the gameplay moving. The core requirement is straightforward: once launched, the program (whether injected DLL or standalone helper) must keep sending the predefined keys to the Spiritvale process on the schedule I set, regardless of window focus. I should be able to edit which keys are used and the interval between presses without rebuilding the code—an external .ini, simple GUI, or console flags will do. Please keep CPU and RAM usage light and make sure the solution is stable during long sessions; if Spiritvale crashes, the macro should fail gracefully rather than freezing my whole system. Source cod...

Full-Stack SaaS Developer Needed for Multi-Tenant Digital Catalog Platform

I need a seasoned professional who can actively search, shortlist, and submit compelling proposals for software-engineering contracts on my behalf. This is a personal initiative, not tied to an agency or corporate hiring team, so I’m counting on your expertise to position me as the ideal candidate each time.
