At PT. Kyoritsu Electric Indonesia, I developed and integrated 15+ REST APIs connecting production, inventory, and reporting systems, reducing manual data entry by 80%. I also work on business applications and technical solutions, from understanding customer requirements through deployment and support.

Previously, at PT. Axis ITSolution Indonesia, I developed desktop applications using VB.NET and web applications using PHP, alongside SQL Server and MySQL databases. I led testing and deployment of manufacturing applications used by 100+ users across multiple departments, reducing system downtime by 30%.

In freelance and small-business projects, I develop React applications with reusable, responsive interfaces and REST API integrations. I'm expanding my TypeScript experience while focusing on modern front-end development with React.
