PROFILE
Swarnava Sengupta
Worked on the vercel/vercel repository to deliver features and fixes that improved deployment reliability and developer experience. Built enhancements to the CLI, including support for bulk redirects in both files and directories for prebuilt deployments, and introduced stricter client-side validation for deployment flags to prevent misconfigurations. Developed an auto-selection mechanism for monorepo projects using repo.json, streamlining the linking process. Later, implemented a dedicated rolling-release start endpoint, replacing the previous promote-based flow to ensure idempotent and reliable canary deployments. Leveraged TypeScript, Node.js, and robust unit testing practices throughout, coordinating closely with API changes to maintain compatibility and test coverage.

Jun 1, 2026June 2026: Delivered a dedicated rolling-release start endpoint for vercel, enabling more reliable and faster canary deployments. Replaced the previous promote-based flow for the rolling-release start, addressing auto-assign edge cases and ensuring idempotent restarts. Added focused unit tests and coordinated companion API changes to support the new endpoint. The work improves deployment reliability, reduces manual intervention, and enhances customer confidence in automated rollouts. Commit e8333304a2607adedc57cfc06c07da966a94d4ca implemented the CLI change to call POST /v1/projects/:idOrName/rolling-release/start with { canaryDeploymentId }.
