About Myself
I'm a full-stack developer who treats shipped and measured as the definition of done — migrations, error states, and production constraints included.
I build data-heavy web products with Next.js, TypeScript, and PostgreSQL, wiring in AI where it removes real work — Gemini function-calling, document pipelines, and YOLO vision. Recent freelance work spans invoice and compliance systems, customer document portals, inventory & formula management, and Shopify sales chatbots.
I also publish research — “ExplainableTrip”, an XAI travel recommender using gradient boosting and SHAP (ISI, 2025).
Software is a promise kept over time. I build things that are still working — and still maintained — a year after launch.
