About Me

Building Real-World Apps That Work at Scale

I'm a senior Flutter & full-stack developer with 4+ years of experience building production mobile apps and backends. I've delivered ERP, POS, F&B, logistics, VPN and finance apps that run in the real world — with thousands of records, offline mode and complex workflows. My main focus today is Flutter: offline-first, clean architecture, and testable, maintainable code. When needed, I design and implement the backend as well — usually with Laravel, secure APIs and role-based admin panels. I enjoy working directly with founders and product teams, clarifying requirements, and turning business flows into reliable, fast, user-friendly apps.
