Hands down, one of my seniors in my bachelor's degree. His name is Mohit.

He helped me out with course materials, gave me guidance on tech and emerging technologies, gave me books, video lectures, cheat-sheets u name it.

Guy is a massive nerd, he used to be holed up in his room for days. And oh yeah, he also wasn't shy with sharing his knowledge and internet downloaded data, which was a pretty massive deal in 2012 when internet and WiFi was crazy expensive.

Also, he would ask me what games I needed so he would download it for me and hand it out for free.

That guy is the reason I even chose tech industry to have a career in to begin with. Last I heard from him, he got fucked up by a girl and decided to move to Bangalore and start a company. That company has net-worth of $4.5 million so he's doing pretty well.
