01 · About

Engineer, builder, problem-solver

I'm a versatile Full-Stack Engineer with deep frontend experience and a strong foundation in backend and cloud. I work day-to-day in Next.js, React, Node.js, and Flutter, and I specialize in building Retrieval-Augmented Generation (RAG) applications and AI-driven products.

On the infrastructure side, I design cloud-native architecture on Azure with Bicep templates and Docker, plus AWS — backed by solid CI/CD so deployments stay repeatable and boring (in the best way).

I like owning projects end to end: from ideation to deployment, with careful code reviews, performance tuning, and a focus on clean, maintainable code and seamless user experiences.

Let's connect — whether you're exploring AI tooling, full-stack workflows, or cloud-native architecture.

Life outside the editor

When I'm not shipping code, I'm usually exploring something new — chasing ideas, side projects, and good stories worth sharing.

Building a Production RAG Pipeline That Actually Cites Its Sources

Retrieval-augmented generation is easy to demo and hard to trust. Here's how I think about chunking, hybrid search, and grounding so answers stay honest.
