You can’t be your team’s bottleneck. You need to coach and mentor your team members to be able to tackle all technical challenges without your help. You should never be needed to write production code. A great use of your coding time is the non-feature dirty work. Make the build faster, extract some shared behavior into a nice library. Look for things that will make things more productive or more fun for the team. You can also keep your technical skills by focusing on coding Proofs Of Concepts, explore new technologies for your team to use, or work on side projects within the company or on your own.
I try to separate my schedules with natural interruptions like lunchtime break. Grouping all my meetings back-to-back in the morning, while exhausting mentally, leaves my afternoon free to wear my Maker hat and concentrate in tough programming problems. I try doing so at least twice a week.
