Mentors go there from all aspects. From engineering to marketing to design. I come from a technical background, and on the first instance I did a presentation but found that it was not as useful as I had hoped. But I noticed a lack of fundamental knowledge around concepts and tech that we use on a daily basis (e.g no monitoring and a lot of manual work being done). Second time I went, I held a 3 day continuous delivery workshop introducing them to concepts like CI, CD and testing. This enabled them to deploy a simple hellow world server through a pipeline with monitoring. The feedback was that the workshop was what they needed.

If you are interested to find out more, I would suggest that you reach out to them and ask them. They have a number of initiatives (e.g coding bootcamps) and its best to understand what they have coming up and where your skills could fit in. Money no doubt would help the GSG organisation but honestly, if you can, I would go there and help on the ground. They need technical mentors more than ever.
