Worked on the janhq/jan repository to deliver a robust server startup verification mechanism for stdio services, focusing on improving backend reliability and user experience. The solution involved implementing a retry loop with controlled backoff and per-attempt timeouts, ensuring that the tools/list endpoint was reachable before emitting the ready event. This approach addressed asynchronous race conditions that previously led to frontend failures and transport errors. The changes were carefully scoped to the stdio code path, aligning verification timeouts with the health monitor and avoiding impact on other transports. The work demonstrated strong skills in Rust, asynchronous programming, and error handling.
