CoSkill

What Inspired Me

Traditional CVs frustrate me. You can claim anything — "5 years of React experience," "led a team of 10" — but there's no proof. Hiring managers can't verify it, and talented people get overlooked because they can't sell themselves on paper.

I wanted to build something that turns the work itself into the CV.
