Wrangling data around is highly sought after - don't undersell it! One idea would be to write about your experiences learning and implementing data transformation in your industry niche, and advertise a consultancy service to help other companies with similar requirements.

You specified you want to earn the money on the side and you allude to not wanting to trade time for money, so it's a perfect arbitrage opportunity to get client work and outsource it, positioning yourself as the manager/architect.

Consultancy was something that I thought about too. But I’m not sure if I feel „ready“ for it. Maybe there is a slight imposter syndrome here. I could see myself do consultant work for a week a month or so, never thought about arbitrage something like this. How difficult is the bureaucracy here? Having employees / paying them + their insurance seems like a lot of overhead to me.

Do you have more information how you would tackle that problem?

You are ready - if you stick to your niche, you'll be competing with consultancies who might not even have a niche and don't have a deep understanding of all the nuances with the data that you do.

Re: bureaucracy - it depends a lot on where you're based, how regulated the industry is, and how sensitive the data is. I wasn't really suggesting hiring employees, you can find remote contract workers on freelancing boards as well (just be careful to filter out all the noise).
