With 3+ years of experience building mission-critical systems, I focus on making engineering operations faster and more reliable. At Sumbu Labs, I architected a vehicle inspection platform that achieved a 50% reduction in operational timewhile handling daily on-chain transactions on the Cardano network.
I specialize in high-impact backend migrations and observability. Recent work includes scaling a production LLM backend at PT Pertamina EP to 8 microservices with zero downtime, and building a 80% more efficient verification system for government digital infrastructure.
Currently, I am deep-diving into AI Agent Frameworks (LangGraph)and modern Observability stacks (ELK, Prometheus, Grafana, OpenTelemetry). I believe the most effective software is not just robust—it's observable and automated at its core.
