Rockstar🎓
Top SchoolJeff Lett is a senior mobile engineering leader with 15+ years in iOS development and over a decade of team leadership, currently heading engineering at CNN after recent roles at Raya and Meta. He combines hands-on iOS expertise—contributing to notable open-source tooling for network stubbing—with product-grade delivery across high-scale consumer apps at Pandora, Amazon Music, and WhatsApp. At Meta and WhatsApp he drove performance, reliability, and app-size budgeting frameworks that prevented regressions and kept growth under control, and at Pandora he led watchOS offline playback to market ahead of competitors. Known for translating complex performance telemetry into actionable release decisions, he builds processes and tooling as reliably as features. Based in Atlanta, he pairs advanced academic training from Georgia Tech with pragmatic release discipline that scales across multinational teams.
