Help with ideation

hi there,
I need some help to narrow down my ideation process.
My priorities would be:

• being able to start asap
• getting sense of progress
• fast validation and knowing I am not losing my time
• my role should be coding/managing, not so much content creation and audience building (not because I am not interested in other tasks, but right now I want a feeling of productivity and accomplishment)

My expertise is javascript, react and some web3/ethereum.
I am looking into starting a small project fast. But this probably should also open more project oportunities for the future

I am interested in Sports, Nutrition, Biohacking and Movement subjects but I my priority would be to find something which is quickly validated and profitable than to try to match my hobbies
