Student wanting to maximise last year of study

Hi,

I'm in my final year of my BSc, major is not data analytics but my minor is. I'm learning SQL on the side, once in comfortable with that I'm going to look into python a little. What can I do to maximise my potential? I've seen people comment about portfolios, I would love any suggestions on how to wrangle that.

For context: used to live in a house truck in the woods. No smart phone or computer. Last six years I've turned life around and taught myself everything, including the tech knowledge I needed before starting university. So I am still new to some things, but I'm working really hard to make myself a decent candidate for jobs. I've got 20 years of workforce experience behind me, up to management level, so I'm not a spring chicken.
