I joined a company 6 months ago.
No CTO.
No development process.
Spagetti code.
Takes loads of new requirements on top.

Later
I advised the software head and managing director on how to improve our software development process.
New tools
Less requirement good quality software
New products and micro services.

Both of them agreed but they said they are waiting for new CTO to confim as an authority and responsibility.

Well I cant do much just to do my work.

1 month ago new CTO joined
Revised whatever I advised and implementing it right. I like it.

Got my confirmation after 6 months instead of 3 months.

CTO called me in for review and gave me 2/5. And said you need to improve more.

I asked him, in what do I need to improve.
He replies in technologies and development process.
And he takes credit for all changes and implementation.

I argued about it. I already suggested what you did but was ignore because we didnt have CTO.
Hes like ignored me.
Fucking you CTO.
