Oh hey. I thought you were going to scroll past. But you decided to stop here. Hi!

After working for (a few) years in technology, and getting the chance to work on some amazing projects, travel to some very interesting places, and work with some very talented people, I decided to start this blog. I wanted to teach what I know and give a hand to people trying to break into the industry!

There no other place like I.T.: constant learning, problem-solving, learning those weird acronyms, and building stuff! When it's great, it's basically like playtime for grown-ups.

But it's not always easy to figure out your own path, what the hell all the technologies mean, or to find the motivation to learn. That's what this site is here for.

I hope you find the content here useful! If you like what you see here, then sign up to the newsletter, so that I can tell you about our new and updated guides, so you can keep your skills f-r-e-s-h.
