About Me

My Story

I'm a Full-Stack Developer based in Jakarta, Indonesia — passionate about building fast, scalable, and meaningful digital products. My current stack revolves around Next.js, Fastify, and PostgreSQL, allowing me to craft modern web apps with solid performance and clean architecture.

I began my career at Indoteknik, where I developed a high-traffic e-commerce platform integrated with a custom ERP system built on Odoo. During that time, I gained deep experience in API design, caching, queue systems, and backend optimization using Apache SOLR to handle large-scale data efficiently.

Today, I'm actively working on projects like Yappin.co — a platform that helps people connect through guided conversations — and SmartCounter, a people-counting system powered by real-time detection and analytics. Both reflect my interest in blending technology with real-world impact.

Outside of coding, I love exploring tech products, listening to music, and going on motorbike tours. I believe great software should be intuitive, reliable, and built with purpose — just like every project I take on. I'm always open for freelance opportunities, collaborations, or meaningful discussions about tech and ideas.
