Summary
🤩
Rockstar🎓
Top SchoolTommy Reilly is a senior software engineer with nine years of recent experience and over two decades in systems and memory-focused engineering, currently building observability tooling at Polar Signals. He has deep expertise in memory management, garbage collectors, and highly concurrent distributed SQL systems from roles at Adobe/Tamarin, NuoDB, and Cockroach Labs, and he enjoys tackling hard problems with a mix of brute-force perseverance and occasional elegant insight. Tommy combines low-level C++ systems work with practical production experience across startups and large teams, including founding a startup focused on educational software. Based in Stowe, Vermont, he brings a pragmatic motto-driven approach—“it’s software; we can do anything” tempered by a healthy respect for what computers actually do—which keeps designs both ambitious and realistic. An unusual strength is his long-term track record of shipping foundational runtime tooling (heap profilers, GC implementations) that quietly enable higher-level product features.
