Rockstar🎓
Top SchoolJason Cheatham is a Senior Software Engineer in Calgary with 13 years of experience building secure, full-stack web and mobile applications for clients and open-source projects. He combines deep security research roots from work at the Air Force Research Laboratory and Riverside Research with practical engineering at SitePen, contributing to projects like the Intern testing system and Dojo extras. His open-source contributions show a rare blend of security, backend systems, and test automation—refactoring cryptographic code, implementing a DynamoDB store, and hardening JavaScript test tooling including Istanbul and Intern. Jason is comfortable across modern stacks (React, Angular, Node.js, TypeScript, React Native) and native platforms (Java, Swift), and he frequently bridges client-facing delivery with low-level debugging and analysis. As a former co-founder of a cybersecurity R&D startup, he brings entrepreneurial initiative and a habit of shipping robust, testable solutions. Colleagues rely on him for solving intermittent, hard-to-reproduce issues and for improving long-lived open-source libraries.
