Summary
👤
SeniorGabriel Hernandez is a Staff Software Engineer and iOS Tech Lead with a decade of experience building mobile and web products, currently shaping the flagship Square POS experience in Toronto. He specializes in iOS architecture and platform leadership, having driven large refactors (removing 25k+ lines of legacy code), raised test coverage dramatically, and reduced crash rates through pragmatic, testable designs. Gabriel excels in startup and scale-up environments, bridging product, design, and cross-functional teams to deliver unified, multi-mode point-of-sale systems used across verticals. He’s shipped greenfield apps and resilient real-time systems earlier in his career—from VoIP and blockchain features to an agricultural forecasting platform that outperformed mainstream providers in rural Mexico. Known for building “safe rails” that empower junior engineers, he combines hands-on coding with operational rigor (oncall runbooks and incident automation) to improve developer velocity and reliability.
