I build durable, well-typed software for teams that have to ship — across web, mobile, and the awkward bits in between. 6 years spanning startups in Yogyakarta, contracts in Hong Kong & Seoul, and the freelance work that keeps the rest honest.
Engineer first, with the judgment of someone who has shipped a lot of products.
With 6 years in product development, I've contributed to dynamic, fast-paced environments — including pre-Series B startups — and have successfully collaborated with clients from Hong Kong and South Korea.
I work fluently across the stack: Next.js and React for the web, React Native for mobile, Golang for the systems behind them. My instinct is to keep architecture small, types tight, and the shipping cadence boring — in the good way.
What I'm best at: turning fuzzy product asks into well-scoped engineering work, and helping the team around me ship without burning out.
- 01Startup pace
Pre-Series B founding-team velocity, owning roadmap chunks end-to-end.
- 02International work
Embedded with teams in Hong Kong, Seoul, and Indonesia across timezones.
- 03Stack reach
Next.js · React Native · Go · Postgres · AWS — picked for fit, not fashion.
- 04Product lifecycle
Discovery → architecture → ship → measure → iterate.
