Introduction

Hi, my name is Stan. And I moved here with my family just about 2 months ago from Russia.

And I'm very nervous now. Because it's my first talk in English. I hope it goes well. But. Anyway. Let's start.

When I started getting into web development a while ago, I was doing mostly PHP. And do you know what I loved the most about PHP? It's how easy it was to start actually doing something.
