Glad you liked it! I took this course (link at bottom) to learn the basics of Optical remote sensing and how to access and process the data :)
To move from processed images to services would take you partnering with someone with some developing skills though, but learning to access to use images is not to difficult.

The course looks quite interesting, but if I devote time to learning some coding skills, I think I would actually start from something less complex and with wider practical application before I move on to more specialized and complex stuff. Which doesn't make this any less fascinating of course :)
