About Me

A bit about me

I'm a full-stack developer with a focus on building fast, reliable, and scalable web applications end to end — from database schema to pixel-perfect UI. I enjoy turning ambiguous product ideas into clean, maintainable systems that ship on time.

Over the past few years I've worked across fintech and e-commerce products, leading migrations to modern stacks, mentoring junior engineers, and owning features from design review through production monitoring.

Outside of work I contribute to a couple of open-source tools, write short technical notes on things I learn, and I'm always up for a conversation about system design or developer tooling.
