Karan Singh Narula

Flutter developer with 3+ years building production apps for iOS, Android, web, and desktop. I focus on clean, modular architecture that holds up as a product scales, backed by consistent testing throughout development. I've been learning to direct AI tools like Claude Code and Gemini within my workflow to raise code quality and catch technical debt early, without skipping the underlying thinking.

Looking for a team where I can own features end to end and help carry a product from an early idea through to launch.
