About me

Full-Stack Developer with hands-on experience building web applications end-to-end — from crafting responsive, user-facing interfaces to designing and shipping robust RESTful APIs and backend services in C# and .NET. I care deeply about clean architecture, SOLID principles, and writing code that's as maintainable as it is performant. Whether it's wiring up a front-end, architecting a database schema, or integrating LLM-powered features and AI tooling into backend services, I bring a full-stack mindset to every project.
