Rockstar🎓
Top SchoolClifford Colvin is a pragmatic engineering leader with 7 years in senior management who now serves as Director of Engineering at Apptio (an IBM company), following his role leading Kubecost through an acquisition. He specializes in scaling cloud-native backend systems and FinOps products—driving an architectural shift from OLTP to OLAP to support 100x scale and stabilizing products by burning down hundreds of bugs across releases. Clifford combines hands-on backend contributions (notably to the open-source Opencost project’s cost modeling and allocation logic) with M&A integration and GTM-facing product leadership that grew standalone ACV tenfold. Based in Georgetown, TX, he’s equally comfortable mentoring engineers and designing scalable data architectures, and he brings a discipline for quality that repeatedly turns fragile platforms into reliable, revenue-driving services.
