Here is a different answer, No it's not ok to drop out of university to work on the tech field. It's ok if you want to be ordinary "Negade" but for the above things you mentioned it's a big NO. Here is why; You leave in Ethiopia, like it or not you are judged by your papers (people won't trust to work on big projects). If you are planning to work on very small local projects it might be okay but i think would want to grow and for that you have to bid for bigger projects and guess what they ask before giving you any project currently ? masters degree. So don't be a fool, having at least one degree won't hurt you.
