Description

Senior Android Developer with over 10 years of experience, expert in the Kotlin and Jetpack ecosystem. Specializing in building large-scale applications, I master the entire development cycle, from modular architecture to production performance optimization.

My philosophy is to produce simple, readable code with well-defined responsibilities. Convinced that technical quality serves business agility, I design robust and scalable solutions that allow for the integration of new features with minimal friction and controlled technical debt.
