At PT. GuardiaTeknologi Indonesia (Jubelio), I led the POS engineering squad and contributed hands-on to checkout, payment, store credit, split payment, loyalty, and store management features. I coordinated implementation across frontend and backend services and supported technical investigations across APIs, databases, and client-side persistence.
Previously at Jubelio, I developed POS and Store Dashboard features with React, TypeScript, and Node.js, including loyalty integrations with Go Fiber services and PostgreSQL. At PT.ModuitDigital Indonesia, I built and maintained .NET/C# backend services and SQL Server databases for mutual fund transaction processing.
