How I Got Into Building Things That Actually Work

Age 4 to 16: Early Signs of "Yup, This Kid's Different"

I was 4 when I got hooked on computers. Not just playing on them... I was genuinely curious about how the whole thing worked. While other kids were outside, I was inside messing with whatever tech I could get my hands on.

In grade school, I found out I could copy reference images almost perfectly. Teachers would throw me into art contests like, "This kid's got something." Cool, but I still preferred screens over sketchpads.

Then came Minecraft. For most people, it was just a game. For me, it was an unofficial engineering tool. I'd build full-on systems, use command blocks like mini scripts, and push the game way past what it was designed for. By 10, I was already messing with logic and code inside a sandbox game.

Same age, we had a circuit project at school. While classmates were trying to figure out which wire goes where, I was already testing extra setups just for fun. None of it felt hard... it just clicked.

Now: Solving Actual Problems, Not Just Building Random Stuff

These days, I work on a mix of tech and design projects. Full-stack dev, PC building, custom LED systems, AI tools, automation, even interior planning for businesses.

I don't just build what people ask for... I figure out why they need it and make something that actually solves the root of the problem.

Like turning a bloated 487MB website into a fast 157MB one. Not for bragging rights, but because slow sites cost people sales. Or getting 100% WCAG compliance for legal websites... not for points, but because people shouldn't be locked out of basic info just because of bad design.

I've also built OCR systems that save hours of manual work, cashless vending machines, and other weird builds most people wouldn't bother trying.

I like making things that actually help people... not just look cool on paper.

Next: Practical Tech That Makes Sense

I'm not too interested in titles like "Full-Stack Dev" or "Hardware Engineer." I just want to keep building stuff that works, solves problems, and makes things faster or easier.

I care about how AI can save time, how IoT can remove pointless tasks, and how smart systems can support real people doing real work.

I want to create tools that other devs can use, keep helping clients build smart setups, and maybe pass on some of this thinking to others who are still figuring it out.

Same Mindset, Just Upgraded Tools

I've always been the guy who asks, "How does this work?" and then figures out how to make it better. That's still how I approach everything... from soldering parts together to coding full systems.

Not here to hype trends. Not trying to impress with buzzwords. Just solving problems with whatever tool fits best.
