Welcome to Steem. I am sure you will get a feel for it fairly quick with your experience in QA and app dev.
If you contribute to open source repos on GitHub please check out https://utopian.io. You will earn massive amounts if you are a good dev with high motivation.
Also check out https://d.tube. The point of using the particular platforms above (they are both built on Steem) is for curation. They support content creators like yourself with increased visibility and payout.
I'll keep an eye on your blog. Good luck
