Backend Engineer · Software Engineer · Co-Founder at Sumbu Labs · Sleman, Yogyakarta · Open to backend roles
I build backend and software systems that need to survive real production pressure: APIs, auth, databases, caching, CI/CD, enterprise integrations, and LLM tooling. My work sits at the intersection of engineering depth, delivery cadence, and practical leadership.
I focus on shipping systems that are measurable, maintainable, and useful — not just technically impressive. That means fast iteration, clear architecture, and an evidence-first approach to every result.
- API design and backend architecture
- Auth, RBAC, and workflow automation
- Database modeling, performance, and caching
- Integration-heavy systems and internal tooling
- LLM backend features and tool-calling flows
