Tech stack may be wrong starting point here. Companies want answers, so if you can get a model that you could pull an insight like “X increase in metric results in Y% increased revenue.”, that’s one path to take.

You could present that in PowerPoint, PowerBI, in a whitepaper, or as a video presentation. The modality only really matters insofar as you think it’s the correct medium for your audience.

As far as stacks its basically whatever your company uses so Azure, AWS, or GCP generally and the tools w/in those.
