László Tuss

Hi 👋🏻 I'm László.

An iOS developer with more than 10 years of experience designing, building and maintaining mobile apps for startups, international companies and my own indie projects. I work in Swift, SwiftUI and Objective-C with deep knowledge of the iOS frameworks and app architecture — system optimization, modularization and product lifecycle. I enjoy mentoring junior developers, working with cross-functional teams, and translating technical solutions for technical and non-technical audiences alike.
