Summary
👤
Senior🎓
Top SchoolJan Lipmann is a CEO, founder and senior iOS engineer with over a decade of hands-on experience building consumer and fintech apps used by millions across Europe. He has led greenfield mobile builds and secure payments features for major retail superapps (Żappka, Jush/Delio) including BNPL, card flows, RSA encryption and JWT token handling. As founder of Appience and former CTO/co‑founder at a consumer app startup, he blends product intuition with pragmatic engineering and team scaling experience. Based in Warsaw, he frequently takes senior iOS contracts focused on SwiftUI migrations, fintech integrations or augmenting existing teams. His career shows a pattern of shipping high‑traffic mobile systems from small teams to large enterprise contexts, and he runs iosfreelancer.com to streamline engagements. An unusual detail: he pairs founder-level strategic oversight with day-to-day secure iOS implementation skills, not just management of engineering teams.
