7+YEARS IN THE TRENCHESSenior mobile engineering across fintech, music-tech and martech, from legacy to greenfield.

Hi, I'm Felipe Oliveira Ferreira. I architect and ship mobile apps that run at scale — Flutter, Kotlin, Swift, and a lot of CI/CD discipline. Based in São Paulo. Open to opportunities and projects.

About

OBSESSED WITH SCALE, QUALITY AND TEAMS.

I started in 2016 building AR and face-detection apps for out-of-home campaigns. In 2018 I jumped into fintech at Guiabolso, and in 2019 joined Digio (Bradesco's digital bank), where I grew from engineer to Android chapter lead.

I led the launch of Uber Conta — a critical product that hit 100k+ downloads and 4.6+ rating in six months. In 2023 I joined MZIC, a US-based music-tech, and architected their app from scratch. Now at Avenue, a global investment platform, leading architecture and CI/CD overhauls.

I believe in real mentorship, substantive code review, and pipelines that take 3 minutes — not 30. I thrive in distributed, multicultural teams.
