Rockstar🎓
Top SchoolKeenan Brock is a seasoned software engineer based in Westford, Massachusetts with 17 years of experience building and optimizing backend systems. He specializes in squeezing large performance wins out of SQL and Ruby—moving heavy work into Postgres and routinely delivering 10x–100x speedups and significant memory reductions (for example, pages cut from minutes to seconds and request memory down by 100+MB). Keenan is an active open-source contributor to heavyweight Ruby projects including rails/rails, RubyGems.org and ancestry, where he added database-focused optimizations, case-sensitive predicates, and profiler-friendly SQL timing. His enterprise background includes roles at Red Hat and IBM helping scale cloud management platforms and improve service throughput, and earlier work delivered similar performance gains for analytics and trading systems. Off the beaten path he also contributes to keyboard firmware (Vial-QMK) and is candid about priorities—his GitHub bio sums it up: he loves his wife, his kids, and Ruby.
