Hi, I’m Gustavo.
I build

mobile apps

for businesses across the globe.

I've worked both on SDKs used by companies such as Uber and Samsung, and on apps featured by Apple. Over the past six years, my code has run on millions of devices.

I served as a squad leader and also had to conduct international clients' support calls. I interviewed dozens of candidates and coordinated the work among the different iOS developers.

SQLite

This is a personal app that I made entirely with Flutter. I co-founded it with a designer and we conducted market and UX research. I was responsible for laying out the technical architecture and the database. Serica is available on both Android and iOS

I was the only iOS developer working on the app and had to implement new features while reducing the existing technical debts. With millions of monthly users, I aimed to produce high-quality code that could easily adapt to changes.

What

I do

iOS Development

I have over six years of experience in making iOS apps. I worked on UI-heavy-focused apps as well as SDK-only projects. I focus heavily on the stability and maintainability of a codebase. I had the opportunity to work on large projects involving millions of users and prototypes for early-stage startups.

Flutter Development

I recently got into Flutter and Dart, which allowed me to target iOS and Android using the same code base. I currently have an app released on the App Store and Google Play Store and will continue to improve my Flutter skills in the future.

Who

I am

Originally from Brazil, I grew up in Belgium and worked in Japan. I now live in beautiful Taiwan where I work remotely for different clients around the world. I love creating my own apps, which I treat like business ventures. This has led me to gain a better understanding of design, marketing, and sales. I believe having this holistic view of products is particularly helpful in smaller teams.
