Profile
About Me
I build across the full stack, from product interfaces to backend systems and AI integrations. My work sits in the practical middle ground: clean architecture, reliable delivery, and software that solves a real business problem. I have experience with B2B systems, B2C products, payments, SaaS platforms, and AI-powered tools, usually taking projects from early technical decisions through production launch.
Product-minded
I build with the user and the business model in view.
Hands-on
I can move from architecture to implementation without losing momentum.
Practical AI
I use models where they improve the product, not as decoration.
