PROFILE

Adrian Cooney

Over four months, contributed to backend and CLI development across the ClickHouse/terraform-provider-clickhouse and vercel/vercel repositories, focusing on security, observability, and developer experience. Introduced a write-only password attribute in Go for ClickHouse, enhancing Terraform state security by preventing sensitive data exposure. In TypeScript, overhauled Vercel CLI log management, adding advanced filtering, live streaming with --follow, and improved error reporting for permission issues, which streamlined debugging and reduced support overhead. Extended deployment log retry windows to improve CI reliability, supported by comprehensive unit testing and documentation updates. Demonstrated expertise in API development, asynchronous programming, and robust error handling throughout these projects.

May 2026: Implemented streaming live logs in the Vercel CLI with --follow, introducing a breaking behavior that requires explicit --follow and treats other deployment arguments as historical log filters. Also extended the deployment log retry window to ~15 seconds to reduce CI integration probe failures and improve startup log availability. Both initiatives included unit tests, documentation updates, and a changeset. These changes enhance observability, reliability, and developer experience, with positive business impact on deployment monitoring and CI stability.

In 2026-04, shipped a focused enhancement to CLI error reporting for permission issues in vercel/vercel. The change surfaces action and resource details from 403 responses in the AgentErrorPayload, updates the error model, and improves downstream debugging and automation workflows. This delivers clearer guidance for users and agents when ACLs block access, enabling faster remediation and reducing support overhead.
