I am currently a software developer in a government agency in my first job out of university. I have been here 6 months. We are in a Scrum environment where each developer is assigned a set number of points to do each sprint. As we do it, they want every developer doing the same number of points each sprint. 

Normally this would screw the junior guy, but because I have the most experience with React as it is new to the agency (where 90% of the work is now), get distracted less than most, and work 1-2 more hours a day than others, I can consistently finish my entire block of sprint work in a week. This week I got to do the CSS for an entire section and was ordered not to take on more work beyond that as our mostly backend engineering team sized it enormously. The sprint started Wednesday and all my work goes to QA tomorrow on Monday. 7 days free...

Because of the "same number of points" thinking, they won't let me pull more work off the backlog, so I end up doing udemy/answer questions on StackOverflow (this is a burner account) /blogging and writing the other half of the sprint. I used to just pull work off the backlog, do it, and tell them to live with it that it was done (and it passed QA and all that), but was told to stop that too. I also enter a ton of innovation challenges and am currently onboarding as a software instructor at our local public college. 

Here is my problem. Resumes are heavily built around jobs and three positions concurrently is absurd.To an employer, you seem distracted and potentially disloyal. 

However, I want to keep the freelancing because it uses technologies I don't get to use for work (monolith vs microservice and message queue systems). The innovation stuff has the interest factor and some nice large names (NASA, Exxon, etc). The instructor job would be a giving back kind of thing. 

I can't leave my current area in USA/Canada due to family constraints and this part is a bit economically depressed right now. My mother is ill unfortunately, so I do not want to be too far away. 

I have two specific questions:

1. How can I advance my career without constantly adding outside jobs to my life? I passed a pile of proposals to several senior managers at the agency and they say they are "evaluating" them.
2. Is there a reasonable way to encapsulate experience gained from many different side things without causing resume problems?
