Grata
Advisor and Acting CTO: Scaling Engineering, Compliance and Performance
Problem
An offshore engineering team produced inconsistent quality with no shared communication or delivery standards.
The mobile apps had major issues with Bluetooth connectivity to door hardware, battery consumption and rendering performance.
Solution
Audited the codebase and team, then transitioned engineering to a local team under Speer’s leadership.
Re-architected the digital key around Bluetooth Low Energy with reconnection strategies, failover handling and real-time error feedback.
Standardized communication protocols, introduced CI/CD pipelines and led the SOC 2 and PCI compliance work.
