What I'm looking for

I'm looking to build scalable web and AI-driven products where I can contribute across backend systems, cloud deployment, automation, and intelligent user experiences while continuing to grow with strong engineering teams.

I've built scalable enterprise web applications at Iykons IT Services using .NET Core, React, and MSSQL, delivering REST APIs, SignalR features, secure authentication, and responsive user interfaces.

At Teceze, I built .NET Core and FastAPI services for AI-driven applications, including RAG architecture with Supabase and Pinecone, n8n automation workflows, and prompt-engineered LLM experiences.

I also build AI healthcare, serverless real estate, ticket automation, dynamic form, and machine-learning projects, while mentoring junior engineers and contributing to clean-code practices.
