I build production-ready web apps and mobile solutions that clients can actually ship — not prototypes. With hands-on experience in C#, ASP.NET Core, Flutter, and SQL Server, I deliver clean architecture and enterprise-grade code that scales. My current focus: integrating AI into real-world applications. I help businesses add LLM-powered features (OpenAI, Claude API, LangChain) into existing .NET systems — from intelligent document processing and chatbots to automated workflows. If you need AI that fits into your stack, not just a demo, I'm the right person. What I work with: → Backend: C#, ASP.NET Core MVC, VB.NET, REST & Web APIs → Frontend/UI: DevExpress, UI3, Razor Views → Mobile: Flutter (cross-platform iOS/Android), Kotlin (native Android) → Databases: SQL Server, MySQL — query optimization, schema design, EF Core → AI/ML: OpenAI API, Anthropic Claude API, prompt engineering, RAG pipelines I've worked with agency clients across business software, ERP Solutions, inventory systems, field service apps, and internal tooling. I understand deadlines, legacy code, and the difference between a clean proof-of-concept and software ready to hand off to a client. If your project needs a developer who won't need hand-holding on architecture, DM me with your brief.
