What I'm looking for

I seek roles where I can build cross-platform mobile and backend systems, work in Agile teams, and grow into technical leadership while delivering secure, scalable solutions.

I am a Fullstack Developer with 2+ years of hands-on experience building cross-platform mobile apps and backend systems using Flutter, Dart, Spring Boot, and Firebase. I have delivered secure REST APIs, optimized backend performance, and contributed to production stability during an internship at a major bank, reducing downtime by 15%.

My projects include AI-powered document validation, a crypto wallet, and e-commerce platforms where I implemented OCR, secure authentication, real-time data, payment integration, and role-based access control. I value maintainable, testable code, and I thrive in Agile teams where I can bridge mobile and backend development to produce user-focused, enterprise-grade solutions.
