What I'm looking for

I’m looking to build production web applications with React/Next.js and Node.js, where I can improve SEO, Core Web Vitals, and UX while shipping scalable, reusable components and measurable performance gains.

I’m a software engineer with 2+ years of experience building and shipping scalable production web applications. I deliver measurable improvements in development velocity, client-side memory usage, SEO, page performance, and mobile listing experiences across multiple client products.

At Concetto Labs, I built reusable Next.js + TypeScript components across three products and reduced new-feature development time by 30%. I architected TanStack Query integration to reduce client-side memory usage by 25%, improved SEO with JSON-LD schema and dynamic category-based sitemaps (70% faster sitemap load), and strengthened performance through Next.js image optimization, virtualized pagination, and an SSR migration that improved a PageSpeed score from 22 to 78.
