Hello, I’m a full stack developer with hands-on experience building with variety of tools including Nextjs, nodejs, nestjs, React, Typescript and more

I focus on writing clear, maintainable code and making sure features work as expected end to end, not just in isolation. I communicate progress regularly and keep things transparent as I work. I’m confident I can complete this task within an ETA of 4 HOURS

Hello Maintainers,

I'd like to work on this issue. I'll implement a unique request ID for every request, ensure it is propagated through logs and error responses, and add the "X-Request-ID" header to all responses. I'll also update middleware and tests to ensure everything works correctly and passes.

Thank you!
