Full-stack developer from Aceh, Indonesia. I build web interfaces, APIs, and the background jobs that keep them connected.
Main stack: TypeScript · React · Node.js · PostgreSQL Currently exploring: worker coordination and failure recovery in Go
Open to remote full-time roles, paid internships, and contract work. Email me · Portfolio
Personal projects with real interfaces, backend decisions you can inspect, and plenty of edge cases.
A WhatsApp support workspace: React inbox, Node.js API, and PostgreSQL-backed message processing.
Worth a look: webhook replay handling, tenant isolation, and keeping background work in sync with a live inbox.

Deadbolt (in progress)

Worth a look: leases, stale-worker safety, and recovery boundaries.
