Raw Data Trainer - Phase 2
Klein delivered Phase 2 of a Unity mobile app involving a complex weather simulation system, haptic feedback, and UI implementation. He handled intricate code integration reliably, was transparent about time estimates, and communicated proactively when he had concerns about the scope. When bugs came up, he was responsive with debug logging and quick to implement fixes. Would recommend and looking forward to continuing work on Phase 3.

Unity Mobile App for Flight Simulation
Klein delivered a complex Unity mobile app involving custom flight physics, instrument displays, ILS navigation, and touch controls. The quality of both the code and the communication was outstanding. He understood the requirements quickly, asked the right questions when clarification was needed, and consistently delivered builds that worked as specified.
What stood out most was his reliability and his willingness to go the extra mile — offering to cover bugs even after the contract ends says a lot about how he works. Looking forward to continuing with Phase 2.
