I ship backend systems that actually scale.
Solo architect of mstore — a multi-tenant ERP & commerce platform for SEA SMEs. Specialized in Go (Golang) microservices and high-throughput distributed systems.
Full-stack engineer.
Solo founder.
Based near Jakarta.
My work spans regulated banking BTPN Syariah, industrial IoT Petrosea, and insurtech IAG — environments where correctness and reliability are non-negotiable.
Today I'm the sole architect and developer of mstore — a large multi-tenant ERP with RBAC, multi-currency PSAK/IFRS accounting, and AI features including demand forecasting, RFM segmentation, anomaly detection, and text-to-SQL.
Database to dashboard to deployment — one person.
