At FyscalTech, I build Go backend systems for Domino’s Indonesia, serving 1M+ users across 248 stores, and for RiskRadar’s AML compliance platform. I’ve shipped 150+ REST APIs, improved peak latency by 30% with Redis caching and idempotency, and built RBAC, feature flags, and asynchronous order workflows.
I also build resilient ingestion and screening systems using AWS SNS, SQS, Temporal, PostgreSQL, ClickHouse, and Redis. My work focuses on clean architecture, transactional data integrity, concurrent processing, and crash-resumable workflows.
