What I'm looking for

I’m looking for a role where I can build and optimize high-performance frontend systems, own design-system quality, and lead roadmap decisions—collaborating with product/design/backend while using AI tools to raise reliability and developer velocity.

I feel the dopamine hit of knowledge is the harmless and free sources of addiction anyone can have. Curiosity is my best friend and I am lucky to have him to transform complex challenges into elegant solutions in my career.
