Since 2018
About
Building things that
just work.
I've been writing backend code professionally since 2018. Started in Java, found Go along the way, and never looked back. These days I design and build distributed systems that handle payments, hotel bookings, and educational content for millions of users across Southeast Asia.
Most recently at Rakuten Travel Xchange, I work on the platform that connects thousands of hotels to booking distributors — dealing with API design, database partitioning, and the kind of optimization problems that only appear at scale.
