About me.

To put it simply, I’m NOT a traditional developer who writes every line of code on my own. Honestly, without any help, I only know HTML, CSS, and Tailwind CSS. However, when it comes to Next.js, TypeScript, React, JavaScript, APIs… I actually rely almost entirely on AI BUT that’s precisely my advantage: I’m able to write very high quality code using the best languages and frameworks. My projects only confirm this they’re validated, generate real revenue, and cover everything from front-end design and backend development to sales and management.

IT administration is an area I’ve been developing for about a month now, teaching myself. (I distinguish between what I learned in school as an IT Technician and my own self-study and hands-on experience.) As of today, without much help, I can handle: Windows/Linux/macOS, WS, LS, AD, DNS, IPv4/IPv6, and MS365. I realize that my skills are at a basic level, and I’m aware of just how much I still have to learn.
