Tiago Marques Nunes

SENIOR ANDROID ENGINEER & SDET

Summary of My Journey

I am a Senior Android Engineer & SDET with over 8 years of experience developing secure, scalable, and high-performance applications for the fintech, retail, and digital identity sectors, impacting a base of up to 400 million users.

My expertise lies in Kotlin, Jetpack Compose, and modern architectures (Clean, MVVM, MVI), alongside a strong foundation in CI/CD automation, unit test development, and UI testing.

I have a proven track record of modernizing legacy code, optimizing performance, and collaborating across cross-functional teams. I specialize in delivering seamless app updates without necessarily relying on store rollouts, leveraging Server-Driven UI (BFF) and modularization.

I am a strong advocate for engineering and software architecture excellence, results-oriented solutions, and AI-enhanced development, driving reliability, speed, and user-centric innovation at scale.

Podcast - ZupCast - Beagle at Hacka4Life 2020 | Portuguese

Our team of developers took part in Hacka4Life, a hackathon aimed at finding solutions to the health and economic challenges posed by COVID-19. Check out the interview to learn about our experience using Beagle, a Server-Driven platform for iOS, Android, and the Web that simplifies the creation of screens through a backend, allowing for changes to screens and native flows using only JSON. We discuss the pros and cons of using this open-source solution in app development!

Spoiler: our team managed to deliver, in 120h an app with back-end and versions for iOS and Android ;)
