About
Professional summaryI am a Software Engineer with over 13 years of experience, including 10 years focused on Android development. I have worked on apps used by millions, internal frameworks, libraries, and open-source projects.
I specialize in building scalable, testable code and applying design patterns and SOLID principles to keep software maintainable. I care deeply about architecture, code quality, and long-term product health.
Throughout my career, I have contributed as both an individual engineer and a technical leader. I have led teams, supported collaboration across product and design, and helped projects succeed under tight deadlines.
My recent experience includes senior Android engineering roles at PayPal, Upwork, and Reddit, where I worked on high-impact products such as instant apps, cross-platform app delivery, collectible avatars, NFTs, and accessibility improvements.
I have also served as a Tech Lead at Zup IT and iFood, where I was responsible for architecture decisions, code reviews, team guidance, and building maintainable mobile solutions. I have experience with MVVM, Clean Architecture, modularization, TDD, CI/CD, and server-driven UI.
In addition to mobile work, I have a broader engineering background that includes Java, Kotlin, Python, JavaScript, PHP, databases, web systems, and backend-integrated products. I also contribute to open-source and side projects, including Beagle and OTClient.
I am based in Brazil and speak English and Portuguese. I am looking for opportunities where I can continue building high-quality mobile software, improving engineering practices, and contributing to strong product teams.
