Sobre mim
What if your web app could load 2× faster and keep users engaged longer?
I help businesses turn ideas into fast, reliable, and scalable web applications that users love. With 2 years of hands-on experience and 20+ successfully delivered projects, I specialize in modern stacks like Next.js, Nest.js, TypeScript, PostgreSQL, MongoDB, Supabase, and AWS.
My approach is simple: performance, scalability, and clean code. For example, I recently optimized a Next.js application with server-side rendering (SSR) and AWS hosting, cutting page load times by 50%, which significantly boosted user engagement
