Software & AI Systems Builder · Computer Engineering @ PCR
I ship production systems end to end — school ops with signed QR attendance, privacy-first web apps, and AI agents that turn messy evidence into verified handoffs.

Computer Engineering student at Politeknik Caltex Riau (D4 Teknik Komputer).
I work across backend, mobile, and agent runtimes — TypeScript, NestJS, FastAPI, Flutter, PostgreSQL, Redis — with a hard focus on auth boundaries, audit trails, device binding, and whether the product actually gets used in the field.
