I previously had a job board that wasn't targeting any area in particular. It didn't worked so i decide to rebrand it on to focus on blockchain technology because i find that it was hard to find a job in this field.

Regarding other big players, i have to agree. But i wanted to create a very simple job board, for developers by a developer. I still have a lot of work but i hope i will be able to differentiate myself from the other websites.
