Senior C# / .NET & React Full Stack Developer | 8+ Years | AI & RAG Specialist

Senior Full Stack Developer with 7+ years of hands-on experience in C#, .NET, and React, building production-grade web applications for healthcare, fintech, and SaaS companies. Over the last two years, I've focused heavily on integrating LLMs and RAG pipelines into existing .NET systems — turning AI from a demo into a feature that holds up in production.

I'm not a generalist who lists every framework on the planet. My core is C# / ASP.NET Core on the backend and React / TypeScript on the frontend, and that's where I do my best work. Everything else (Azure, AWS, vector databases, CI/CD) supports that core.

𝐖𝐡𝐚𝐭 𝐈 𝐡𝐞𝐥𝐩 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐛𝐮𝐢𝐥𝐝:

- C# / .NET backends — ASP.NET Core Web APIs, microservices, Entity Framework Core, Dapper, SignalR

- React frontends — React, Next.js, TypeScript, responsive UIs, component libraries, state management done right

- AI features in .NET apps — RAG pipelines, Azure OpenAI integration, semantic search, vector embeddings with pgvector / Pinecone / Azure AI Search

- Full stack SaaS products — from database schema to deployed React app, including auth, payments, and admin dashboards

- Legacy modernization — migrating WinForms / WPF apps to modern React + .NET Core web stacks without breaking the business

- Cloud deployment — Azure and AWS, Docker, Kubernetes, Azure DevOps CI/CD
