My thoughts about AI
AI made me a better builder
I started designing interfaces. Then I wanted to build them myself.
At the beginning, I had no clue how it worked. I tried learning to code several times but always got frustrated. Then I discovered WeWeb—a no-code AI builder that helped me understand logic, workflows, components, and database design. Everything started clicking.

Then tools like Cursor and Claude Code came out. I gave them a try, and now I'm all in.
It's not about replacing teams or leaving everything to AI. I'm learning more about code every day—but now in my own way, with my own products, through my own experiments.
