Hey, I'm Nikolas. I'm a product engineer who's always curious about how we build things – and how AI is making us rethink it all. I believe good products come from understanding the whole picture, from the big idea to the final code.

This is where I share my journey and ideas, hoping to find other folks passionate about building what's next.
