Gee, thanks. (I think.) No, seriously, I'm a real-life code slinger and have been doing it for over 20 years.
Am I an expert in every topic I write about? Sadly not. But if the topic is in the enterprise arena, there's a good chance I've got some hands-on experience there.
I always try to call 'em like I see 'em, whether I've been working with the tech stack 15 years or 15 days.
