Zack Robinson

Summary

Technical program lead with 8+ years delivering mobile platforms in regulated, high-reliability environments: healthcare (Dexcom G6/G7, CVS/Aetna), crash detection (CCC), logistics (JJ Keller), streaming (STARZ), and quick-service retail (McDonald's). Senior engineer by background (native Android, now also iOS), which means estimates, risk calls, and release decisions grounded in how the system actually works. Strong in release readiness, incident triage and root cause analysis, cross-functional coordination across engineering, product, QA, and design, and turning recurring delivery failures into durable process and automation.
