Hello, my name is Felipe Nipper
I build native Apple experiences — from on-device AI that turns a video into a recipe, to playlists generated from a sentence. Eight apps shipped on the App Store, and counting.

About
About me
My journey in app development began in 2020, when I started studying Software Engineering at PUCRS. The program's strong curriculum and focus on agile methodologies gave me a solid foundation in programming — and sparked the passion for building apps that I still work from today.
In 2021 I joined the Apple Developer Academy, where I worked on several projects and built a deep understanding of Apple's development ecosystem. That experience shaped how I approach software. In 2022 I had the honour of winning the WWDC22 Swift Student Challenge, Apple's annual competition celebrating student developers worldwide.
I graduated from PUCRS in 2024. Throughout that time — and ever since — I've independently designed, built, and shipped the apps you'll find on this site. Today I work as an iOS engineer at a software consulting company, while continuing to ship and maintain my own apps on the App Store.
