I'm looking for a frontend or full-stack role on a product team, where I can own features end to end with React, Next.js, TypeScript and Node.js. I'm especially interested in products built around AI, and in teams that review code and ship often. Remote, full-time or long-term contract. Available immediately.

@valeraanfer
Frontend & full-stack developer: React, Next.js, Node.js. 25+ high-traffic sites, a ride-hailing app in production, 10+ client projects.
VenezuelaWhat I'm looking for
I'm a Frontend Engineer with nearly 5 years of experience building with TypeScript, React, Next.js and Tailwind CSS.
At Futbol Sites – Better Collective, I worked for 4 years on a network of more than 25 sports media sites in LATAM, some with more than 5M daily users. I optimized Core Web Vitals and brought all three metrics into the green, reducing LCP from 3.5 s to 1 s. I also migrated the multi-site architecture to Next.js 15 with App Router and React Server Components, and built reusable, configurable components that cut a new site's front-end setup from 3–5 weeks to one day.
As a freelancer, I keep One Rides, a ride-hailing and delivery app in production, stable by fixing production issues, and I implemented a Node.js webhook that automatically validates bank transfer payments, plus abuse-prevention features. I've also delivered more than 10 client websites, online stores and web apps, from Figma designs to pixel-perfect, mobile-first code.
I use Claude Code daily, and I'm looking for frontend or full-stack roles on product teams.
