Rockstar🎓
Top SchoolJonathon Shallow is an experienced full-stack engineer and DevOps leader with a decade-plus passion for software that began writing JavaScript from a tent in Afghanistan. He blends hands-on engineering—spanning frontend, backend, databases, CI/CD, cloud architecture, embedded/IoT, and DevSecOps—with leadership as DevOps Team Lead at BAE Systems and as an adjunct professor teaching practical CS. A former Black Hawk pilot who now serves as a 255A Information Systems Technician in the New Hampshire Army National Guard, he uniquely pairs operational discipline with production-grade software delivery. His open-source work includes substantive protocol-level improvements to libcoap and esp-idf (DTLS and multicast support), reflecting deep systems-level and embedded networking expertise. Fluent in translating RFC-level requirements into robust implementations, he excels at bridging military, academic, and commercial tech environments.
