Like you, I'm super protective of my inbox, so don't worry about getting spammed. You can expect a few emails per month (at most), and you can 1-click unsubscribe at any time.
Nick has become an invaluable mentor for me. In fact, he emailed me with a job opportunity, which I successfully applied for. Without Nick, I wouldn't have landed my new job as a back-end web developer!
Your courses are paying off in spades. They've help taken my skill level from hobby-level enthusiast to getting asked to interview for developer positions. I sincerely thank you for helping me better understand programming.
