Half the feature is the lesson: how Kieran Klaassen runs Cora without touching the code
Blog post from Render
Kieran Klaassen, running Cora at Every without needing to write or review code, has created an AI-driven email client trusted by thousands of paying customers. His approach, termed compound engineering, leverages AI agents to handle most of the implementation work, allowing him to focus on ideation and review. Kieran's system runs on a loop of ideation, brainstorming, planning, implementation, review, and polishing, with a compounding step ensuring lessons learned are captured for future use, thereby improving efficiency and reducing costs. By spending equal time on building features and capturing insights, Kieran has developed a robust framework where agents manage heavy lifting, while he ensures that each iteration improves upon the last. This system was exemplified when a deployment failure, involving a 500-million-row table, led to an updated lesson that prevented future errors, showcasing the adaptability and learning capability of his agents. Kieran's preference for technologies like Rails, React, and Render facilitates streamlined operations, enabling a platform that remains unobtrusive during normal conditions but fully inspectable during failures, enhancing both productivity and reliability.
