ALFONSO CERRATO Senior Frontend Engineer

< About />

Hey folks! 👋 I'm a web frontend engineer with around 8 years under my belt. I've been on the grind, making products shine and boosting conversion rates through A/B testing. Acting as a growth engineer, I thrive on experimentation and a data-driven approach to drive impactful results. I speak JavaScript fluently, and my go-to framework is Next.js. Also, I've dipped my toes into the mobile world using React Native.

I'm all about getting down to the nitty-gritty of our products, trying to make every website visit a win-win for users and the company.
