I build the systems
products rely on.
Backend / Platform Engineer · 8+ years · Solo (UTC+7) · Remote with US/AU teams
I help product teams ship 40+ production services that stay observable, scalable, and safe to change — from 20+ microservices at KWRI (US) to 1M SMS/hr (AU) and a 100% → 30% hospital platform fix (ID).
Platform outcome: Standardized observability + Pub/Sub patterns — new-project onboarding weeks → days
Reliability outcome: Hospital PgBouncer + k3s — zero-downtime releases, horizontal scale
Scale outcome: Migrated 10+ services AWS → GCP/GKE; multi-tenant platform with shared auth

04 / ABOUT
Breadth as leverage,
not noise.
I work best at the seam between application code and production infrastructure: shaping service boundaries, tracing failures through distributed systems, and leaving teams with patterns they can reuse.
My foundation spans backend, cloud, data, and selective frontend work — helping me make platform decisions grounded in how products are actually built and operated.
