About
Hello, I'm Jakub Florek, a second-year Honours BSc Computer Science and Engineering student at the Delft University of Technology.
I'm actively contributing to the Swift Programming Language's swift-syntax repository, particularly to the SwiftLexicalLookup library, which I initially developed during Google Summer of Code 2024. The library's main focus is to provide modern APIs to interact with lexical scopes in Swift code.
I'm a three-time Apple Swift Student Challenge winner, having won in 2021, 2022, and 2024. As an iOS developer, I've created apps such as the local public transport schedule app TarBUS, the internal enterprise kitchen plan editor JPK, and an open-source Welcome Sheet package with APIs to create native-like iOS onboarding screens.
Personally, I'm an avid guitar player with a passion for hiking, traveling, and photography.
Projects
tarBUS
From 2021 to 2024, tarBUS served thousands of passengers in Tarnów, becoming the most popular local transport app on the App Store and Android. As a co-creator, I was responsible for the iOS app, developed in partnership with Michalus transport. With over 5000 downloads, it became a regional success. This project taught me valuable lessons in mobile development, teamwork, and app deployment. One of my favorite features was customizable widgets displaying live bus departures from selected stops.
