I’m a Senior Android Engineer with 8 years of experience building scalable mobile applications across banking, finance, and enterprise platforms. I’ve worked on high-availability systems serving millions of users, including projects for Itaú and BMG Bank, as well as multi-country enterprise solutions like BEES Force. What makes me unique is my combination of strong mobile architecture skills and cross-domain experience. I’ve worked not only in Android but also in frontend and backend environments earlier in my career, which allows me to understand systems end-to-end and collaborate effectively with different teams. I specialize in Kotlin, Jetpack Compose, Clean Architecture, and automated testing. I particularly enjoy refactoring legacy systems, improving stability, and building maintainable, scalable mobile solutions. I’m currently looking for a remote international role where I can contribute to technically strong teams working on complex, impactful products.
