Senior Full Stack Engineer at iSeatz who modernized a white-label platform, improving LCP by 50%.
ArgentinaWhat I'm looking for
At iSeatz, I evolved a legacy React SPA into a Next.js and TypeScript white-label monorepo adopted by multiple enterprise clients. The work improved LCP by 50% and reduced new Checkout calls by 30%.
I streamlined CI/CD and cloud delivery, reducing review build times by 40–70%. I also added more than 155 accessibility tests toward WCAG 2.1 compliance and strengthened production observability.
Before iSeatz, I worked on travel Checkout experiences and reusable enterprise UI components, then developed payment and billing platforms at DonWeb. I’m currently seeking opportunities in global, remote-first teams.
