I’m a Flutter mobile developer with 4 years of experience building scalable cross-platform apps, mentoring teams, and optimizing performance.

What I'm looking for

I’m looking for a role where I can build and scale Flutter mobile apps, integrate REST APIs and Firebase, optimize performance, and mentor others—while delivering production-ready features for real users.

I’m a results-driven Flutter Mobile Developer with 4+ years of experience building scalable, production-ready cross-platform applications used by thousands of users globally. I focus on clean architecture, reliable REST API integration, and Firebase services to deliver real business value.

In my recent roles, I’ve refactored state management from Provider to Riverpod to improve scalability and maintainability, and I’ve shipped features like subscription billing, social authentication (Google Sign-In), and real-time user experiences (newsfeeds with comments, likes, and auto-refresh). I’ve also contributed to apps reaching 100,000+ downloads and 5,000+ daily active users.

I enjoy collaborating with teams across the product lifecycle—planning, implementation, performance tuning, and iteration—while supporting learning and technical growth. As a Mobile Developer Mentor, I guided developers through the Flutter development lifecycle and supervised capstone projects from concept to deployment.
