Senior🎓
Top SchoolTommy Chheng is a seasoned engineering leader with 16 years of experience building teams and production systems across startups and large enterprises, currently serving as Head of Engineering at Speak in San Francisco. He combines deep expertise in AI, information retrieval, and search systems with a pragmatic track record of shipping customer-facing products—from booking platforms on Ethereum to subscription and identity systems at WeWork. Known for hiring and scaling distributed organizations (50+ engineers) while maintaining low attrition and high eNPS, he also led major migrations to SaaS solutions like Auth0 to simplify stacks and cut costs. Tommy’s background spans low-level research (satellite image detection using OpenCV) to data-intensive pipelines and search (Quid, Qwiki, Yahoo), giving him rare fluency across ML, big data, and full-stack engineering. He favors measurable engineering excellence initiatives—quarterly “excellence days” and targeted optimizations that reduced outages and improved performance by orders of magnitude.
