§01 · About

Building systems that handle money, scale, and time correctly.

Backend developer with 3+ years building production systems across fintech, search, and travel. Currently based in Singapore, shipping payment infrastructure and store-credit wallets at Wine Adore using Go, FastAPI, PostgreSQL, and GCP Cloud Run.

I care about financial correctness, audit trails, and systems that stay honest under concurrent load. Outside of code I'm drawn to the same principles — clarity, restraint, and things built to last.

B.Sc. Informatics, Udayana University, Bali — GPA 3.90 / cum laude.
