I'm a Civil Engineer, doing my master's in Ocean Engineering, a TeX enthusiast and expl3
advocate.
I first used LaTeX to write a paper to a conference on Ocean Engineering in 2014. I absolutely hated it. However, by the end of 2015 I got the hang of it and never came back to Word (except when forced to, 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 :)
