Flutter Developer | Affordable Secure Apps for All Platforms

I'm a Flutter developer with over 3 years of hands-on experience building scalable, secure, and high-performance mobile and web applications. I specialize in cross-platform development using Flutter for Android, iOS, and web, with a strong focus on clean architecture, performance optimization, and secure coding practices.

I have worked as a Flutter developer at a military institution, where I delivered mission-critical solutions with strict security and performance requirements. In addition to my development expertise, I bring strong skills in mobile application security and have deep familiarity with OWASP Mobile Top 10, reverse engineering, secure storage, and real-time input validation.

Key skills:

Clean Architecture (App/Data/Domain/Presentation layers)

MVVM Pattern, Stream Controllers, Dependency Injection

RESTful APIs, Firebase (Auth, Firestore, Storage, Cloud Functions)

Secure development: input validation, encryption, secure file handling

Flutter Web and Desktop apps

Penetration testing and security auditing for mobile apps

I’m passionate about building user-centric, secure, and maintainable applications. If you're looking for a developer who understands both the frontend experience and the backend security implications — let’s talk.
