I'm Victor Felder and
vhf are the initials I usually use on the Internet.
I'm a university trained computer scientist. As a software engineer, I have been working in the Big Data field for a while before deciding to go back to designing, implementing and scaling web backends.
I spend time contributing to the open-source ecosystem by authoring open-source tools and software, creating open-source projects, writing technical articles, filing issues and fixing bugs in interesting projects.
