Unfortunately, you may need to let go of your tech work, or shunt it over to "nights and weekends."
I was a manager for 25 years, and one thing that I learned, was to never put myself into the critical path. I could do tech projects, but they needed to be "nice to have on the side" projects.
Management requires that we work on interrupt. We can't have that sweet "fugue," that makes us productive developers.
What I did, was work on a lot of open-source stuff, on the side. I didn't have deadlines, and it allowed me to keep my "tech chops" up.
Since leaving that job, I tossed the management stuff into the skip, and have concentrated 100% on tech work. I love it.
I'm a damn good engineer. I get a hell of a lot done, at awesome quality levels, in very little time, but I also don't particularly care whether or not anyone co-signs my work.
Also, I'm not a jargonaut. Lots of folks like to sneer at people like me, because we suck at Buzzword Bingo.
