12 years building production .NET systems. Fintech payment orchestration at Agoda, SaaS invoicing platforms, legacy modernization on Azure and AWS. My work is backend-heavy full-stack. Clean C# architecture, REST APIs built to hold up under real load, and frontends in Blazor or React that don't embarrass the backend. I've owned entire codebases solo and led small teams through complex deliverables. I'm most useful when a project is messy, stalled, or needs someone who can hit the ground running without hand-holding. Done this repeatedly on Upwork and in enterprise environments. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⚙ Backend: .NET Core | ASP.NET Web API | EF Core | C# 🖥 Frontend: Blazor WASM | React | Redux | Angular | TypeScript 🗄 Databases: SQL Server | PostgreSQL | Redis ☁ Cloud: Azure | AWS | Azure DevOps | GitLab CI 🔗 Integrations: Stripe | Xero | FreeAgent | HMRC | Amadeus | FedEx | DHL ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ If your project involves .NET, a data-heavy backend, or anything in fintech or SaaS, let's talk.

Top Rated Plus (Top 1% on Upwork) | 100% Job Success | 3,800+ Hours Billed | HIPAA & Privacy Law Certified (UPenn) Most of my work over the past 10 years has been backend systems where failure gets expensive. A payroll platform that pays US businesses on time, every cycle. An EHR holding patient records for two healthcare organizations in Florida. A B2B platform a Silicon Valley startup runs its sales intelligence on. All shipped, all live, all still running without me babysitting them. That last part matters. As a Full-Stack Developer, I build systems that hand off cleanly: documented APIs, CI/CD pipelines on Azure, databases another developer can read in a week. You own the code, and you can run it without me. What I actually do as a Backend Developer: REST APIs and services in ASP.NET Core, C#, and Python (FastAPI, Django). Database design in PostgreSQL, MySQL, and SQL Server. Microservices and multi-tenant SaaS architecture. On the frontend, React and TypeScript. For mobile, Flutter apps live on the App Store and Play Store, including one with 500K+ downloads. HIPAA work is a specialty, and I'm certified: Privacy Law & HIPAA through the University of Pennsylvania. I've built EHR/EMR systems, EVV home care platforms, and hospital task management tools. If your product touches patient data, I already know what an audit looks for: encryption at rest, access logging, role-based permissions. I also do AI Development inside real products. LLM features, automation, and agentic workflows using Claude and OpenAI APIs. I use Claude Code and Cursor daily, so AI-assisted delivery speed comes standard. Clients typically hire me as a Full-Stack Developer or Backend Developer for: SaaS platforms and API-driven web applications HIPAA-compliant healthcare software Fintech and payroll systems with third-party integrations Flutter Mobile App Development, backend included Rescuing or scaling an existing ASP.NET Core / React codebase Every project comes with 45 days of free maintenance after launch, and larger builds get extra specialist hands under my lead when the scope calls for it. My longest Upwork contract ran 1,739 hours with the same client. That's the kind of working relationship I build. If you want a second opinion on your architecture or a straight read on scope and timeline, message me. Worst case, you walk away with a clearer plan.
