Top SchoolMatthew Jarjoura is a mobile application developer with 15 years of experience building high-performance, user-focused products across startups and large tech firms. He has shipped major iOS and cross-platform features at Apple, Foodspotting, OpenTable, and Meta, including custom camera systems, offline photo workflows, Maps integrations, and a Maps-first Events experience used by millions. Comfortable in Swift, Rust, C++, Kotlin and backend languages, he blends low-level systems thinking with polished front-end UX to optimize reliability and real-time performance. At Meta he delivered carrier-compliant RTT telephony, a discreet personal safety product, and low-powered WebRTC interfaces, demonstrating skill in constrained environments and regulatory requirements. A pragmatic mentor and early team builder, he has led small teams, hired engineers, and created onboarding tools to bridge technical and non-technical users. He pairs deep platform experience with an appetite for performance engineering and elegant product design.
