About/ 01
Self-taught engineer, end-to-end builder.
I'm a Senior Software Engineer who designs, builds, and ships native mobile apps (Android & iOS) and modern web platforms — owning features from architecture through release.
My core stack is the JavaScript/TypeScript ecosystem: Node.js and NestJS on the backend, React and Next.js on the front. I care about clean architecture, fast load times, and micro-interactions that feel right.
Lately I've been wiring AI into real products — chat assistants, LLM-powered tools, and RAG pipelines that turn raw data into conversation.
No CS degree — every line learned by building. Five years, three platforms, twenty-five-plus shipped products.
