I am 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 worked in Big Data for a while before deciding to go back to designing, implementing and scaling web backends.

I spend a lot of 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.
