About

I'm Severus Melvin, a PPLG student at SMK Raden Umar Said Kudus, currently in my fifth semester. I lead teams and build software end to end — mobile, web, and the systems behind them.

My work spans enterprise asset management at PT Patra Jasa, commercial POS systems, and award-winning AI apps built under hackathon pressure. I care about motion, clarity, and products people actually enjoy using.
