Who I Am

Software Engineer with 3+ years across the full mobile stack — building production Flutter and Android apps, optimizing PHP/Node.js backends, and tracking down vulnerabilities as a security analyst at EY GDS.

At Educational Initiatives, I authored 45,000+ lines of Dart code, directly touching 39.7% of the entire codebase across 22 modules. I've architected foundational systems (global scaling, permission engine, design tokens), built complex dashboards from scratch, and shipped 190 PRs across a single year.

I care about clean architecture, measurable performance improvements, and systems that don't break in production. Outside work: Godot, Unreal Engine 5, and Kotlin DSA.
