What I'm looking for

I am seeking remote roles building cross-platform Flutter apps where I can apply security-first mobile architecture, automated CI/CD, and responsive UI skills to deliver scalable products.

I am a results-driven Flutter and mobile app developer with 2+ years of freelance experience building cross-platform iOS, Android, and web applications. I combine a security-first mindset from my cybersecurity background with strong Flutter expertise to deliver pixel-perfect Material Design UIs, optimized performance, and cost-efficient Firebase architectures.

I have delivered 6+ production apps with 100% client satisfaction and 70% repeat contracts, automated CI/CD pipelines with GitHub Actions and Codemagic, and identified and remediated critical vulnerabilities during a cybersecurity internship. I focus on shipping faster, safer products that scale for startups and SMEs.
