Nikita Bhattacharya
Senior Mobile App Developer
Senior mobile — Flutter, React Native & native Swift/Kotlin at scale
About
I ship consumer apps that millions actually keep installed, and I chase the numbers that matter: crash-free rate, app size, frame times and retention. Five years across health and fitness, currently owning a Flutter companion app with 800k+ downloads — and mentoring the developers building the next release.
