I wish I could pair program more. I have so much knowledge to give other members of my team. Domain knowledge, programming knowledge, common pitfalls, etc. You get a code review pass at the time of writing the code, and it means you have more opportunity to change things for the better. Once it's written there's not much appetite for drastically changing working code during code review unless there's a really good reason.
But it's usually contained to someone like a junior calling me up and saying "can you help me?". The answer is always "yes of course!" and I share as much as I possibly can. But it ends there.
I just want to sit down and show them things. Teach them in a way that makes things "click" the way I found they clicked with me. But I don't think management really values this approach. We get siloes of knowledge and then when someone leaves it's all hands on deck to transfer that knowledge.
I'm often brought onto projects as a firefighter because I'm seen as productive. But I think the more important thing for the team would be to have me upskill everyone else below me. But for whatever reason, it's hard to get that point across to management. I can see myself in a few people and that they have potential, they just need encouragement.
