// About Greg

GK
Greg Kowalczyk

Oakville, Ontario

I'm an engineer who builds things. I graduated in 1997 and started as a draftsman, then designer, then design team leader, and finally Manager of Engineering for a 70-person department at PRO-ECO / SMS-Siemag — fourteen years on global-scale industrial projects.

In 2011 I left the corporate job and spent the next eight years as a consulting engineer, working across a lot of different companies. In 2014 I started building e-commerce brands with my daughter — two of them, running ever since. I learned SEO, ads, and marketing by doing it rather than reading about it, and spent $2M+ on advertising across Google, Amazon, and Meta. From 2019 the consulting shifted to e-commerce.

I started using AI in production in 2022 — Jarvis first, then Jasper, well before most people had heard of any of it. When ChatGPT and Claude arrived I went deep. Since then: custom tools that replaced $75K+ in agency costs, two iOS apps shipped without a coding background, and a lot of other businesses helped to do the same.

Now I build AI systems for businesses that want working solutions, not strategy decks. Everything I recommend, I've tested on my own businesses first. With my own money.
