At KSP Mitra Sejati Persada, I develop and maintain RESTful APIs and backend services for a multi-tenant SaaS POS platform using Laravel/PHP and PostgreSQL.
I also design responsive web applications with Next.js and built a lightweight Go printer bridge to connect web applications with local thermal printers.
At PT. Subaga Digital Medika - Transmedic On Site Team, I developed and customized healthcare information system features and integrated external APIs, including BPJS V-Claim, SATUSEHAT, and E-Klaim.
Earlier, at PT. Pro Sigmaka Mandiri, I developed backend applications with Java Spring MVC and Spring Boot and implemented frontend applications using JavaScript, React.js, and Vite.js.
