Andrew Yousef is a senior software engineer in the San Francisco Bay Area with 11+ years building production-grade mobile and backend systems, currently focusing on Android/iOS contracting and consulting. He was an early engineer at Crittercism/Apteligent, where he led Android SDK development, raised test coverage above 80%, and designed systems that processed tens of thousands of requests per second for 100M+ devices. At Heap and prior roles he combines runtime instrumentation, professional SDK design, and backend work—able to both “put out fires” in operations and invest in long-term architectures and automated testing. His background as a physical chemist gives him a disciplined, experimental approach to problem-solving and a knack for measurable, data-driven improvements. He favors simple, well-tested code over unnecessary complexity and has hands-on experience with crash symbolication, network instrumentation, and distributed caching at scale.
