What I'm looking for

I'm open to international relocation and visa sponsorship, and I want to build reliable distributed systems and AI-powered products in a high-scale environment.

At DANA Indonesia, I build and operate Java, Spring Boot, and Apache Kafka microservices for a digital wallet serving 30M+ monthly active users and millions of daily transactions.

I built DANA's Model Context Protocol server from the ground up, securely exposing wallet capabilities to AI agents. I've also delivered LLM-powered financial coaching and payment-receipt extraction features at production scale.

I lead small teams and own services end to end, from design and rollout through SLOs, on-call response, and observability. Previously, I built regulated identity systems at Privy and full-stack HR software at PT Docotel Indonesia.
