What I'm looking for

I’m looking for a role where I can build Kotlin/Android products across devices, work in an agile environment, and lead delivery with the CTO—shipping high-quality features with modern architecture, testing, and great user experience.

I have more than 19 years of professional experience in the I.T industry in Barcelona and London, designing and implementing complex systems for internationally renowned organisations. I bring deep expertise in elearning, CRM, and gaming, and I’ve spent years building tools end-to-end—from model and views to production-ready app architecture.

For the last years, I’ve worked across Kotlin Multiplatform, Android, and backend services. I’ve delivered Kotlin Multiplatform chat experiences with Jetpack Compose and MVVM, built Android apps to enable kiosk access without a key, and developed APIs using Ktor for user login and profiles by client. I’m comfortable translating product goals into scalable, testable implementations using patterns and modern Android tooling.

As Android Developer Lead in Ludium lab, I designed and developed new features for Sora Stream across mobile and Android TV, leading a team of 3 people and keeping continuous communication with the CTO to achieve company objectives. I also build with an execution mindset learned from startup experiences—growing products like Wakeup.ly and Wake up incomes by combining engineering, architecture, and marketing strategy to launch and acquire users.
