Executive Summary
Driven frontend engineer who doesn’t back down from challenges. I have thrived at small startups where I had to figure things
out independently and deliver results without much guidance. I take ownership of my work, from translating designs into
polished, production-ready components to ensuring accessibility and performance standards. Looking for a team that values
someone who puts in the work and wants to grow alongside the company.
