What I'm looking for

I seek senior React Native roles focused on high-performance cross-platform apps, robust CI/CD and cloud integrations, collaborative teams, and opportunities to architect scalable mobile solutions and mentor engineers.

I am a Senior React Native Developer with over 6 years of experience building high-performance, scalable mobile applications.

I have reduced app load times by 45% and cut response times by 30% through architecture and performance optimizations, while streamlining CI/CD pipelines to improve release velocity and reliability.

As a consultant and team lead I manage end-to-end CI/CD (GitHub Actions, Bitrise, Fastlane), testing strategies (Jest, Detox, Appium) and mentor teams to adopt best practices for maintainability, security and performance.
