What I'm looking for

I'm looking for senior mobile engineering roles where I can lead architecture, improve performance, mentor teams, and work on scalable products with strong CI/CD and backend integration.

I'm a senior mobile developer with 4+ years building high-performance, user-focused applications for large-scale audiences, including apps with over 1 million active users. I specialize in Flutter/Dart, Kotlin and Swift, and pair mobile expertise with backend experience in Spring Boot, Node.js, Ruby on Rails and Golang to deliver maintainable, scalable solutions.

I've led architecture and performance work across startups and established teams, improving deployment times, engagement and system performance through CI/CD automation, modular design, GraphQL integrations and native bridges. I'm committed to applying software engineering principles, mentoring teams and continuously growing my technical skill set.
