What I'm looking for

I’m looking for a team where I can lead end-to-end mobile delivery—React Native/Flutter architecture, GraphQL/REST integrations, and automated CI/CD—while mentoring others, improving performance, and building intuitive, reliable user experiences.

I’m a Senior Mobile Engineer with 12+ years shipping production mobile applications across healthcare, fintech, and consumer products. I build scalable mobile solutions and obsess over performance, code quality, and automated testing—delivering apps that maintain 4.5+ star ratings and serve millions of users.

I specialize in the React Native and Flutter ecosystems, with deep native skills in Swift, Kotlin, Java, and Objective-C. I’ve led technical initiatives end-to-end—from beta distribution (TestFlight/Google Play) and store submissions to post-launch monitoring—while improving reliability, cutting deployment time by 50%, and driving measurable business outcomes through analytics, GraphQL/REST integrations, and robust CI/CD (Jenkins/Fastlane).
