SUMMARY
Senior Flutter Developer with 12 years of experience in software development and 6 years focused
on Flutter and Dart, building scalable cross-platform applications for iOS, Android, and Web. Over
the past 2+ years, I’ve worked as a team lead, mentoring engineers, improving code quality through
reviews, and helping teams deliver consistently in Agile environments. I take ownership from
planning to release, ensuring reliable delivery with CI/CD.

I’m experienced in Flutter development across complex UI, responsive and adaptive layouts, pixel-
perfect design implementation, animations, and platform integrations. I work on offline-capable
features, API integrations, and data-heavy screens, with a strong understanding of Dart, including
async programming, isolates, and concurrency. I apply object-oriented and functional programming
approaches, work with various state management techniques, follow mobile app security best
practices, and prioritize testing and code quality to build reliable and maintainable applications.
