Jann Driessen
Software Engineer

I love building exceptional mobile and web apps with user-friendly interfaces, minimalist designs, and subtle animations.

15+ years experience. Led app teams, founded startups, shipped apps used by millions. Early to iOS, early to fitness, early to DeFi and blockchain. I know what it takes to build well at every stage: early-stage, scaling a team from 0 to 20, and enterprise-level delivery.

Selected work includes growing the mobile engineering team at Freeletics (100k+ MAUs), supporting Bloom in building their iOS mental health app and hiring the app team, supporting the initial development of HUK-COBURG's telematics app (1M+ downloads), shipping the first version of Vorwerk's Thermomix iPad app, and contributing to Index Coop — a DeFi protocol with $500M+ TVL.

I work with startups and established companies on fullstack and mobile app development. Get in touch — let's build something together.
