I'm a full-stack developer based in Indonesia — currently a Backend Engineer at Eduqat. Node.js and React are my daily drivers: backend services and APIs on one side, front-end features on the other — backed by years of PHP and AWS experience on high-traffic marketplaces and enterprise platforms.

Backend Engineer based in Indonesia
I'm a backend-focused full-stack developer with 6+ years of professional experience — from engineering high-traffic REST APIs for Indonesia's largest vocational marketplace, to building enterprise platforms at regional scale, to architecting microservices for an LMS on AWS.
I enjoy working across the stack: Node.js and NestJS on the backend, React and Next.js on the frontend, PHP and CodeIgniter where it counts, and serverless infrastructure that stays out of the way. What I care about most is that the result is stable under load and easy to maintain.
