Android Developer Engineer
About Me
I am a strategic Senior Android Engineer with over 10 years of experience building high-performance, scalable native applications. I specialize in Kotlin, Jetpack Compose, and MVI/MVVM architectures, and have a proven track record of leading cross-functional teams and delivering mission-critical features for global platforms including CNN, PayPal, and iFood. My expertise lies in modernizing legacy codebases, increasing test automation, and mentoring engineering teams toward technical excellence.
Throughout my career, I have engineered scalable architectures from the ground up, such as the "Shorts" video feed for CNN, which became a primary engagement driver for their mobile app. I leverage modern Android technologies and architectural patterns to ensure high-performance and seamless user interfaces.
I have led migrations from XML to Jetpack Compose, modernizing significant portions of applications while maintaining strict delivery deadlines. I am experienced in managing cross-functional teams, conducting code reviews, and mentoring developers to improve engineering standards.
My work includes delivering core features for large user bases, increasing unit test coverage significantly, and stabilizing architectures with robust dependency injection frameworks like Hilt. I have also contributed to improving network performance and user onboarding flows, resulting in measurable business impact.
I am passionate about applying Clean Architecture principles and Kotlin best practices to build reliable, maintainable, and scalable Android applications. I thrive in agile environments and enjoy collaborating with backend and iOS teams to deliver high-quality software solutions.

Experience
Engineered the "Shorts" video feed from the ground up, designing a scalable architecture that became a primary engagement driver for the mobile app. Leveraged Jetpack Compose and MVI to ensure high-performance video rendering and a seamless user interface. Contributed to architectural scalability to support high-traffic global events and real-time news delivery.
Architected and led the migration from XML to Jetpack Compose, modernizing 50% of the app’s UI while maintaining strict delivery deadlines. Designed new features using Jetpack Compose with an MVI-style unidirectional data flow (state/events/effects). Directed a cross-functional team (Backend, Android, iOS), managing sprints, 1:1 mentorship, and rigorous code reviews to improve engineering standards. Engineered secure data protocols for direct communication with emergency services (911), ensuring 100% uptime and compliance with public safety standards.
Delivered core features for a US-based user base of 200M+, focusing on codebase stability and high-concurrency performance. Increased unit test coverage from 32% to 87%, significantly reducing regression bugs and improving deployment confidence. Led a strategic refactor to stabilize the MVVM architecture and implement Hilt for robust dependency injection.
Scaled the Restaurant App supporting 400,000+ business partners, ensuring reliability for the largest food delivery platform in Brazil. Facilitated the modernization of native modules and collaborated on cross-platform integration strategies to improve development velocity. Mentored junior and mid-level developers on Clean Architecture and Kotlin best practices.
Optimized network performance, reducing backend requests by 40% through intelligent local caching and UI state management. Improved the user onboarding and login flow, leading to a 17% increase in successful account conversions.
