About Me

Senior Flutter Developer with 4+ years of professional experience building production Android and iOS applications across ride-hailing, fintech, and e-commerce.

Specializes in Clean Architecture, Bloc/Cubit, and reusable, maintainable mobile codebases — with hands-on experience in REST API integration, Firebase, payment systems, and real-time application features.

Comfortable owning products end-to-end from architecture and CI/CD through production deployment, with experience extending into backend development (Node.js, Python/FastAPI) and AI-assisted development tools when a project calls for it.

What I deliver end to end — from mobile architecture and store releases to backend APIs and dashboards your team can run day to day.

Mobile App Development

Flutter apps for Android & iOS — architecture, integrations, and store-ready builds.

Production-grade cross-platform apps: Clean Architecture, Bloc/Cubit state management, REST APIs, maps, payments, real-time features, and CI/CD toward Google Play and the App Store.

Backend APIs & Dashboards

REST APIs, admin dashboards, and web clients — clear UX, roles, and data at a glance.

Backend services with Node.js, NestJS, Python, or FastAPI — REST endpoints, PostgreSQL data models, Redis caching, and authentication workflows — plus operator dashboards wired to your APIs or Firebase.
