I've gotten feedback that I could be more of an expert and provide insights more smoothly on past projects I've delivered. However, I've been at the company for many years, so there's a lot of stuff attributed to me. How can I be an expert on all these things without being overwhelmed?
Where are you currently writing down the FAQ and "runbook" for each project? That'd be my first instinct here -- how can you get as much of the knowledge in your head (which will decay over time) into an easily accessible wiki or resource?
