I'm a Civil Engineer, currently doing my master's in Ocean Engineering, a (La)TeX enthusiast and an old-school programmer (Fortran >> These new stuff).
I first used LaTeX to write a paper to a conference on Ocean Engineering in 2014. I absolutely hated it :P
By the end of 2015 I got the hang of it and never came back to Word (except when mandatory, in which case I curse a lot).
Recently I created the EoTeX document class, as the official thesis template for the postgraduate program I'm in, but anyone is free to use it. There are a few nice features and many, many, bugs. Check it out :)
Para os usuários Brasileiros de LaTeX, eu sugiro (e também uso) o novo site em português, mantido por Stefan Kottwitz, o LaTeX.net. São todos bem-vindos lá também :)
