Rockstar🎓
Top SchoolRafe Kettler is a software engineer with 15 years of experience building reliable, high-performance systems, currently focused on distributed data storage and payments infrastructure at Square in San Francisco. He designs and operates large-scale MySQL/Redis clusters and automates petabyte-scale OLTP storage while collaborating with application teams to scale data retrieval and durability. Previously he built core internal payments APIs that move money, navigating fragile legacy dependencies and strict correctness and fault-tolerance requirements. Comfortable across Go, Java, Python and the ops toolchain, he owns software through design, implementation and production maintenance. He also documents and clarifies complex topics—authoring a detailed guide to Python’s magic methods—bringing a teacher’s eye to developer-facing systems. Practical, curious, and hands-on, he enjoys “hacking” on hard problems that sit at the intersection of correctness, performance, and operations.
