I’m Kerry Racz, a full-stack developer with 6+ years of experience building and shipping B2B SaaS products using TypeScript, Node.js, and React. I’ve founded and scaled a SaaS product from scratch, and I’ve also led engineering work from the ground up—taking ownership of architecture and delivering end-to-end features with a strong focus on production quality. My background includes working with serverless and cloud environments (GCP and Azure), implementing CI/CD and automated testing (unit, integration, and end-to-end), and improving observability to speed up debugging and performance. I enjoy combining hands-on engineering with team leadership—hiring, coaching, and setting technical direction—and I’m available for remote, fixed-term contract missions.
