I am a software developer with experience in building web applications. I turn product ideas into fast, typed, and deployable web systems with a backend-first sense for reliability.

focus // what-i-build

Where I do my best work

Three lanes I keep sharp across every build.

Backend systems

API layers, queues, sockets, auth, observability, and data contracts that are ready for production traffic.

Frontend System

Dense, fast interfaces with type-safe components, motion feedback, and layouts that stay calm under real content.

AI product work

RAG pipelines, LLM integrations, tool calls, and UX patterns that make model output inspectable.
