About Me

I'm a Software Engineer with over 3 years of experience at PT Gajicermat Mandiri Digital Indonesia, where I've built multiple mobile apps and web applications for finance and HRIS services.

Previously, I spent 2+ years at Tokodistributor, a B2B marketplace, where I significantly improved web performance, increasing PageSpeed scores from 35 to 90 points and implementing comprehensive SEO optimizations.

I hold a degree in Electronics and Instrumentation from Universitas Gadjah Mada (UGM) and have contributed to various open-source projects.
