Top SchoolJoseph Lawson is a senior software engineer with over two decades of technology experience and 13 years in hands-on engineering roles, currently advancing cloud-native systems at NetSpeek. He has led cross-functional teams to productionize regulated medical software—driving Dexcom’s first therapeutic product, closed-loop insulin research platforms, and 510(k)/CE transition efforts—combining clinical collaboration with rigorous verification and security practices. A pragmatic architect and individual contributor, he designs scalable AWS and GCP backends, high-throughput simulation pipelines, and PWA solutions that balance privacy (envelope encryption for PHI) with offline capabilities. Joseph is an active open-source contributor with notable backend work on GoReplay (traffic capture/replay) and enhancements to moto’s AWS mocking for EC2 and CloudFormation testing. He excels at turning greenfield research concepts into auditable, compliant systems and mentoring scientists and engineers to adopt production-grade software and testing practices. Based in Virginia, he pairs systems-level thinking with a people-first approach—“I write software. I love people.”—that drives pragmatic innovation.
