What I'm looking for

I seek roles where I can lead mobile and cross-platform product development, build performant SDKs, and work on AI/blockchain projects with strong CI/CD and team mentorship.

I am a Senior Flutter developer with a Master’s in Advanced Computer Science and 5+ years of industry experience building scalable mobile and web applications, SDKs, and blockchain-enabled products. I lead end-to-end development, design CI/CD pipelines, and drive performance and security improvements across iOS, Android, and web.

I have delivered production SDKs used by major banks, reduced load times dramatically with innovative caching strategies, and built AI-powered and blockchain-backed products for agriculture and fintech. I prioritize clean architecture, TDD, strong UX, and mentoring teams to ship reliable, compliant software.
