single word requests - What is a noun or adjective to describe somebody who juggles work, study, hobbies, family and more?

I'm trying to describe someone who burns the candle at both ends. They work full-time, they study full-time, they have creative projects on the go, they raise their family and manage their property - etc... all at the same time.

I want to use a word to sum this up but will also hang a small definition on (similar to what is above) after the word to clear up what it means.

Words like multi-tasker spring to mind but this does not convey the meaning I want to give. I also considered words like dexterous and agile - but again, these don't seem quite right.

Given that people often use the term 'juggling' to describe people that 'juggle' their work, study and private lives, I thought there might be a nice adjective to describe the skill that a good juggler has but I can't find something suitable for this either.

Any help or ideas greatly appreciated. The context is that of a reference for employment or a CV.
