SpainWhat I'm looking for
With over 11 years of experience as a Staff/Principal Android Engineer, I have successfully led distributed teams to modernize legacy codebases and enhance scalability for Android applications. My expertise in Kotlin, Jetpack Compose, and Clean Architecture has enabled me to drive key business KPIs, boost developer productivity, and achieve exceptional app stability. I am passionate about mentoring engineers to senior-level roles and building high-performing teams.
In my current role at Trainline, I spearheaded the modernization of our Android app, implementing a two-year roadmap that significantly improved our crash rate and test coverage. My previous experience at Hopper involved bootstrapping a new tech team and establishing agile development processes, resulting in rapid growth and successful product launches. I thrive in remote-first environments and am dedicated to delivering user-centric applications through modern architectural patterns.
