Summary
🤩
RockstarEvert Pot is a seasoned staff software engineer with 25 years of experience designing and modernizing backend systems, currently based in Old Toronto. He blends deep expertise in software architecture, APIs and JavaScript package management with hands-on contributions to notable open-source projects like sabre-io's CalDAV/CardDAV stack and michelf/php-markdown. Evert has founded and led engineering teams and companies—running a successful agency, co-founding fruux, and serving as CTO—so he comfortably spans coding, product architecture and operational leadership. His work often focuses on protocol-level interoperability and data integrity, from VObject date-time fixes to unified DAV endpoints and Composer-based dependency modernizations. He pairs startup pragmatism (bootstrapping SOC2-compliant systems and secure secret handling) with enterprise-scale thinking gained at companies like Yelp and Filemobile. Not obvious at first glance: he’s repeatedly driven projects that translate protocol standards into reliable, production-grade services used by large platforms and integrators.
