About
A mobile engineer with product instincts and internals fluency.
React Native Developer with 2.5 years of experience building and shipping production mobile applications for iOS and Android serving 25K+ users. Open-source contributor to React Native Core at Meta and LangChain.js, with contributions reviewed and approved by maintainers.
Career Story
Nikhil has moved through agency MVPs, field-service platforms, healthcare collaboration, airport networking, and AI document tooling while keeping the work close to production reality: crash rates, app ratings, low-network reliability, release pipelines, and reviewer-approved open-source contributions. He has shipped iOS and Android features for products serving 25K+ users, built offline-first workflows for field teams, and implemented real-time tracking, push notifications, deep linking, search, identity verification, and media-sharing experiences. His work combines product ownership with platform debugging, performance tuning, automated releases, and a strong bias toward mobile systems that keep working after launch.
