Building Digital Solutions
That Actually Work

A brief introduction about who I am and what I do.

I'm a Fullstack Engineer and SEO Specialist with hands-on experience building web applications, managing backlink strategies, and maintaining server infrastructure. Currently working as Technical Support Staff at Rumahweb Indonesia while running an independent SEO consulting practice.

Graduated from Universitas Sebelas Maret (GPA 3.67), I combine strong technical foundations with real-world delivery — from sentiment analysis systems and backlink marketplaces to self-hosted infrastructure running 10+ services.

I manage the full stack: frontend, backend, databases, Docker, Nginx, DNS, SSL, and server monitoring. Everything runs on infrastructure I built and maintain.
