Summary
👤
Senior🎓
Top SchoolJoshua Milas is a pragmatic software engineer with 12 years of experience building reliable backend systems, deployment automation, and embedded infrastructure from prototype to fleet-scale. Based in Newtown, CT, he designs reproducible deployments—using Singularity, Ansible, Docker, and CI—to shrink update windows from hours to minutes and has led QA efforts from zero to a staffed, automated team. He’s contributed meaningful fixes to high-profile open-source projects like Locust and JupyterHub, improving load-testing behavior and token-based auth/metrics integration. Comfortable working across hardware and software, he has resolved driver issues with partners and created build servers and spawners that connect users to GPUs and other resources. A former adjunct professor, he also builds tooling to make teaching and testing repeatable (markdown-to-notebook converters, automated grading scripts). His early curiosity for taking things apart shows in a consistent knack for automating tedious workflows and improving system observability and reliability.
