A bit about
me.

Oktavian Alle

I'm a Software Engineer based in Salatiga, Indonesia. I studied Informatics at Satya Wacana Christian University (UKSW), where my thesis built a web-based sales system for a local wood and ceramics retailer, and I later designed relational databases for both a district attorney's office and a university facilities department.

I work across the stack, mostly with Laravel and React, plus C# and .NET from a backend bootcamp at Formulatrix. I've trained a churn-prediction model with Python and Scikit-learn, and shipped SIMAFTI — a full-stack asset management system with QR-code tracking, role-based access, and a live dashboard.
