Works
I don't just write code — I architect systems that carry real business weight: payment flows that move money, tracking platforms that run 24/7, and public-sector tools held to government-grade compliance. Below is selected production work from 10+ years in Singapore. Some is under NDA; where I can, the card links to the live system or the engineering story behind it.
