About

Engineering products, not just features.

I'm a full-stack TypeScript developer with 3+ years of commercial experience building SaaS platforms, MVPs and AI-powered applications from the ground up. I work end to end — from data modeling and API design to polished, performant interfaces.

My focus is on shipping reliable, maintainable systems: clean architecture, thoughtful developer experience, and products that hold up under real-world usage. I care about the details that separate a prototype from a production product.

Whether it's integrating language models into an existing workflow or scaling a backend to handle millions of records, I bring a senior engineer's judgment to every decision.
