What I'm looking for

I am seeking opportunities that allow me to leverage my Android expertise while fostering innovation and collaboration in a dynamic team environment.

As a Senior Android Developer with over 7 years of experience, I specialize in building and scaling native Android applications using Kotlin and Jetpack Compose. My journey has taken me through high-impact environments, including fintech and global B2B platforms, where I've led end-to-end feature development. I am passionate about writing clean, testable code that delivers value to millions of users.

Currently, I lead Android initiatives at AB InBev, impacting over 16 countries. My focus on automation, CI/CD, and performance optimization has allowed me to improve delivery velocity by 30% and reduce release bugs by 40%. I thrive in collaborative environments, working closely with backend, QA, product, and design teams to ensure pixel-perfect implementations while mentoring junior developers and supporting architectural decisions.
