About

Money-app calm, full-stack depth.

I'm a full-stack engineer who lives in the JavaScript ecosystem — React, Next.js and Node — and I care about the whole pipeline: clean UI, solid APIs, and infrastructure that doesn't fall over at 3am.

Lately I've been pushing past 'just building features': studying AI/ML in depth, drilling system design, and tightening my DevOps so I can take an idea from a blank repo to a deployed, observable, scalable product on my own.

Daily LeetCode keeps my data-structures & algorithms sharp. I learn loudly, ship often, and document as I go.
