David Kelly is a senior software engineer with 13+ years of hands-on experience designing and optimizing scalable, distributed systems across cloud platforms, VR, and big data. He earned early recognition at Oracle for horizontally scaling a full-text search engine (holding a patent) and today leads advanced LLM implementations, vector database integrations, and high-performance backend work at Couchbase. David pairs deep systems knowledge with practical DevOps and CI stability improvements—his open-source contributions include stabilizing the Couchbase Java client and improving Spring Data Couchbase compatibility for Java 11. As a former Director of Engineering, he mentors teams in test-driven development and rigorous code review while guiding architectural transitions from vertical scaling to cloud-native distributed designs. Colleagues describe him as a pragmatic problem-solver who blends research-grade physics training with production engineering discipline. Outside of work he channels the same discipline into amateur boxing and caring for his pit bull, Diesel.
