So I onboard this guy on the project. One week in we worked on a task. There was a socket hang-up error. After a lot of debugging, I realized the issue was the value being sent over RPC to the API. Resolved in a huddle with the guy to show him how I debugged and found out.

2 weeks later, the client uses the API elsewhere, and runs into the same error, opens ticket. The new guy picks it up. After spending a day, says he can't find the issue, let alone reproduce it.

I have to jump in.

My guy, we just went through this recently. How much did he accumulate in 2 weeks since we did that, that he can't recall the fix
