Hi, I'm Emir Bernal

I'm an

Crafting high-impact AI and machine learning solutions with 7+ years of experience.

About Me

I began as a self-taught tech enthusiast 14+ years ago, giving me a unique perspective on learning. My passion lies in optimization - I thrive on challenges where the destination is clear, but the path is unknown. This drive, combined with my technical expertise and adaptability, enables me to tackle complex problems and consistently find the most efficient solutions.

"I love optimizing anything, especially when we know the goal but not how to get there."
