Rockstar🎓
Top SchoolSam Jewell is a Staff Software Engineer and pragmatic tech leader with 11 years’ experience building scalable data and web platforms, currently driving SQL Expressions and cost-attribution work at Grafana Labs. He blends hands-on engineering—strong Ruby/Rails, SQL/Postgres, Python, Apache Beam and Go—with product-minded data work, having led BridgeU’s Data team to reimplement recommendation engines and double recommendation speed. At Grafana he shipped a Go-only SQL engine reimplementation that unlocked major performance gains and influenced multi-million dollar ARR opportunities, and contributes to the popular open-source Grafana backend for SQL expression features. Sam pairs technical depth with people-first leadership: mentoring engineers, shaping SLOs to reduce toil, and fostering a culture of feedback and continual learning. His background in mechanical engineering and UX-informed product design gives him a unique cross-disciplinary perspective that helps turn complex data problems into usable, business-driving features.
