Top SchoolRaymond Mattingly is a Staff Engineering Lead at HubSpot with nine years of experience building and operating large-scale distributed data platforms, specializing in HBase, Spark, and Iceberg.

A hands-on engineering leader and Apache HBase committer, he’s implemented server-side improvements to HBase core behavior (slow logs, RPC throttling, read quotas) and developed a cluster autoscaler that cut daily costs by over 15%. He pairs system-level technical depth with people leadership, routinely automating alerting, testing, and upgrade workflows to enable safer, prod-like experiments. Based in Boston, he brings a pragmatic focus on measurable impact: throughput at trillions of row operations per day and tangible cost savings for business-critical infrastructure.
