About

Solving Problems Through Code

I turn complex business challenges into elegant digital solutions. As a Fullstack Developer specializing in Next.js, React, and Node.js, I've delivered 4+ high-stakes projects worth IDR 1B+. From custom dashboards to real-time monitoring apps, I build solutions that users love and businesses depend on.

Great code is built on two pillars: velocity and sustainability. I've accelerated team productivity by creating reusable scaffolds, design systems, and CI/CD pipelines. As a technical lead, I mentor developers and translate complex decisions into clear documentation.

My toolkit spans the full stack: React & Next.js for UIs, NestJS & Express for APIs, PostgreSQL & MongoDB for databases, and Docker for deployment. But tools are just means to an end. What drives me is solving real problems: making teams faster, users happier, and businesses more successful.
