Developer mindset.
Product focus.

I build user-centric mobile products with Flutter, modern architecture and reliable backend integrations.

My experience spans scalable Bloc + Provider architecture, REST APIs, Firebase, authentication, payments, maps, testing, CI/CD and production release management. I enjoy turning product requirements into clean, maintainable experiences.

I am also the founder of Fluverse Technologies, a software and app development company headquartered in Silvassa that takes on client projects across Gujarat and Mumbai.
