About
A bit about me
I'm a detail-oriented engineer with a track record in highly regulated environments — banking at DBS and government-adjacent work at ST Engineering. I care about the unsexy stuff: clean integrations, reliable automations, and systems that hold up under pressure.
Outside of enterprise work, I build personal tools at the intersection of finance and AI — a Telegram trading bot, an AI-powered interactive portfolio, and more coming.
