[01] — About

Engineer.
Builder.
Mentor.

Hey! I'm a Senior Software Engineer with 7+ years building web apps that are not just functional, but genuinely useful to people. I've worked across fintech, healthtech, hospitality, and edtech — bringing ideas to life and solving real problems through code.

I enjoy working closely with teams, product managers, designers, and fellow engineers to turn complex challenges into simple, elegant solutions. Over the years, I've led projects, mentored developers, and built my own startup — so I understand both the technical and product side of things.

My proficient tools include JavaScript/TypeScript (React, Node.js), Python (FastAPI), and cloud-native tech like Docker and Kubernetes. But more than any stack, I'm all about building with care, learning constantly, and creating impact through thoughtful software.

The best developers aren't the fastest typers — they're the clearest thinkers. AI is a thinking tool, not a replacement for judgment.
