What I'm looking for

I seek backend or systems roles where I can build reliable, high-performance services, improve data pipelines, manage compliance, and help teams scale with a collaborative culture and strong engineering practices.

I am a senior backend engineer focused on building correct, performant systems that solve real business problems. I specialize in backend APIs, distributed systems, and data infrastructure, and I enjoy designing resilient services at scale.

At Awantunai I led RBAC redesign, company-wide user management, and an automatic logging and auditing platform using Spring annotations, Debezium, GCP Pub/Sub, and BigQuery so engineers and auditors can self-query full business flows.

I designed trade financing and POS offline support systems that dramatically improved operational efficiency — speeding internal chores nearly 10x and increasing new user activity by 5x — while also optimizing database performance to achieve p99 latencies under 300ms.

Previously at Gudang Ada and Pegipegi I built and tuned CRUD and complex promo engines, ETL and streaming data pipelines, and search/pricing feeds using Java/Spring Boot, integrating multiple databases and third-party systems to reduce latencies and improve scalability.
