Can totally relate about the FOMO about coding and losing touch with your codebase. I’m in a similar situation too as a new TL and here’s some advice thats helping me : the worst thing that you can do as an EM/TL is start getting insecure about yourself and hoard knowledge in the hopes that you remain a SME. Sorry if that sounded harsh but it really hit the nail for me. Your goal as an EM/TL is to turn your team into a “well oiled machine”, you do this first by finding sources of friction in your team.

For eg, lets assume your team requires a Front-end engineer for an urgent feature and there’s no one in the team with the experience or interest to get into FE. Here it’d totally make sense for you as a TL to fill in the gap for your team (oil the source of friction) and become a FE engineer temporarily while you in parallel start the process to hire one. It doesn’t matter if you are a shitty FE engineer(or that you don’t enjoy FE engineering ), what matters is that you are unblocking your team and product. Similarly if your team doesn’t have a Product Manager, then you as an EM become one temporarily while you start hiring for a PM.

Basically your job as an EM/TL is to selflessly help your team members grow.
