I build scalable backend APIs, databases, and integrations for user-facing platforms.

At Mampu.io, I designed referral and reward systems with dynamic business rules for 20K+ users, built event-management features, and integrated e-Materai digital signing into the core system. I also build scalable RESTful APIs with Java Spring Boot and improved performance by up to 40% through SQL query and indexing optimization.

I've delivered backend services with Laravel, Go, Docker, MySQL, and PostgreSQL for Topremit, XTEND Integrasi Indonesia, and Studybox.id, where I also helped build a booking and payment experience using React, Java Spring Boot, and Midtrans.
