Sergio G.

I’m a full-stack developer who blends AI-powered development tools with modern coding frameworks to deliver fast, scalable, and production-ready applications. I specialize in building custom web apps from idea to deployment, using both AI builders for rapid iteration and traditional code for precision and scalability. My toolkit includes: - AI Builders & Tools: Replit, Lovable, V0, Google AI Studio, Rork, n8n, Zapier - Frontend: React, Next.js, TypeScript, JavaScript - Backend / APIs: Node.js, Supabase (authentication, database, edge functions, pgvector), REST & GraphQL APIs, Firebase - Databases: PostgreSQL (via Supabase), real-time sync, secure RLS policies 🔹 What makes me different: I can bridge the gap between AI/no-code speed and custom code power. That means faster delivery, lower costs, and software that scales. 🔹 What I deliver: - Modern, responsive React / Next.js frontends - Secure Supabase backends with authentication, RLS, and serverless functions - Node.js APIs and integrations with third-party services - AI-powered workflows to ship MVPs and SaaS faster without sacrificing quality Whether you need a full-stack MVP, scalable SaaS, or AI-integrated app, I can build it with efficiency and flexibility.
