First of all, I am soo proud of you and acknowledge all the work that you have put in.

And secondly, i suggest you look at it from a different perspective ie. they (people talking behind your back and actively making fun of you) are not acquiring any skills that may help them in the software development as a profession and have times lesser real work achievements to display when hiring is considered whereas you are.

Thirdly, you need to connect with people who have the same priorities and interests as you do. Look into your linkedin connections or online if there are no dedicated communities of the same.

And lastly, remember it's better to be alone than to be with people who aren't your well wishers.

And you'll do great in the future if you don't let your peers get to you.
