(03)About
Building at the speed of curiosity.
I'm Matheus Nicolas, but you can call me TzDev. I'm 23 and I mix design and code to turn ideas into real products.
My thumbnails have driven over 500M YouTube views for top creators including Like Nastya (130M+ subscribers), Khalid Al Ameri, Corey Funk, Koreannosh, and Hudson Matter.
Right now I'm building Adventure AI and shipping web apps and mobile apps end-to-end — integrating APIs, Google Cloud and whatever the product needs — alongside thumbnails, logos and landing pages.
On the AI side, I fine-tune pre-trained models and run advanced workflows in ComfyUI — building custom pipelines for image generation, identity and style transfer.
Good product is the sum of aesthetics, performance, and story.
The dream? Build a 🦄 unicorn startup from scratch.
