Senior🎓
Top SchoolColin Dellow is a founder and seasoned software engineer with 14 years of experience building high-performance, data-driven systems and large-scale integrations. He led engineering at Sortable, architecting petabyte-scale warehousing, real-time ad ops integrations, and algorithmic shopping platforms using Scala, Python, Clojure, Postgres, Redis and Elasticsearch. Earlier work at Microsoft focused on protocol-correct identity and federation (SAML, WS-*)—giving him deep expertise in security, interoperability and threat modeling. As founder of SyncWith since 2021 he combines product leadership with hands-on backend development; his open-source contributions to the Go-based carbonapi project show a practical knack for extending time-series tooling with features like movingMin/movingMax and compatibility-preserving flags. Based in Waterloo, he blends startup grit, enterprise-grade engineering, and a preference for clean, backward-compatible solutions.
