Meet Gerrit

I'm Gerrit. I build launch-ready iOS apps for founders who need to ship fast.
Every app is native SwiftUI, built by me personally, and delivered to TestFlight in 7 or 14 days. You work directly with the person writing your code. No handoffs, no account managers, no surprises.
When a project needs deeper design or backend support, I bring in trusted specialists. Still one point of contact. Still fixed scope. Still fast.
