I build the frontend and the API behind it. Right now that means Central Pattana: moving the Seller Center commerce platform onto serverless AWS, and building the interfaces that sit on top of it — a mall kiosk solution, and a floor-plan tool that visualises financial data on an interactive map. Before that, identity verification for Thai retail banking and internal tooling for a digital asset exchange. Systems where correctness matters more than polish.

Senior engineer on internal tooling at Thailand's largest digital asset exchange. Built the recovery flow for assets sent on-chain to the wrong address, returning them to the customer. Rebuilt the asset listing process for the operations team — fewer manual steps, faster, harder to get wrong.

How to use EC2 and ECS
An e-learning platform for an English tutor: secure video lessons with time-boxed access, nine kinds of exercise for pre- and post-testing, invite links that grant a bundle of videos at once, a blog CMS, and an immutable audit trail behind the admin tools. I built and run all of it.
B2B wholesale pharmaceutical commerce, built for pharmacies rather than consumers. Buyers register with business documents and wait for approval, then submit a quote instead of an order; staff adjust quantities against real stock and approve, which reserves stock and creates the order in one transaction. Multi-unit products, a promotions engine, points, and a full back office sit behind it.
A course platform for a Thai pharmacy-licensing tutor — course listings, dated announcements, student testimonials, and enrolment. Built mobile-first; most of its traffic is on a phone.
Contract work, scoped from things I have already built and run in production. Hire through a platform for a contract and escrow, or email me directly.
Move a slow or fragile service onto managed queues and functions without a rewrite. Measure first, migrate the hot path, keep the old system serving until the new one is provably better.
Commerce that does not fit a standard cart: approval before purchase, quotes instead of orders, multi-unit pricing, stock reserved on approval, promotion rules that actually compose.
Video and materials that only the right people can reach, for the window they paid for. Time-boxed permissions, bundle invites, exercises with grading, and an audit trail over every admin action.
Remote or Bangkok-based, full-time or contract. Email is the fastest way to reach me — I read everything and reply to anything specific.
