About Me
My Journey & Experience

I'm a 25-year-old developer with a strong drive to understand how things work and make them better.

Since I was a kid, I've been drawn to technology - not just using it, but breaking it down, asking why, and figuring out how to push it further. When someone says something can't be done, I see that as a reason to try.

I'm always exploring new tools, tech stacks, and ideas. Learning is a constant part of my routine, and I enjoy solving problems in ways that are both practical and thoughtful. I don't like vague answers. I believe the “why” matters.

I love sharing what I'm working on and learning from others. I tend to talk fast when I get into something I'm excited about, which happens a lot. For me, building things isn't just work. It's what I genuinely enjoy.
