Senior🎓
Top SchoolDavid Ellis is a pragmatic Senior Software Engineer with over a decade of professional experience and a 17-year passion for software, fluent in Ruby, Crystal, Go and JVM languages. He has led end-to-end projects across backend and frontend work—designing scalable ingestion pipelines, extracting legacy services into Go microservices, and building internal security tooling for privilege reviews. At Shopify he simplified OAuth flows to enable serverless apps in the App Store, and at PagerDuty and Rackspace he drove high-throughput, horizontally scalable systems foundational to product offerings. With an MS in Computer Science and a habit of shipping side projects to learn new tools, he pairs clear communication and domain-focused problem solving with a practical, ownership-minded approach. Based in San Antonio, he’s collaborative, quick to learn, and deliberately avoids ego while fixing hard engineering and business problems.
