Sobre mim
Hi, I'm Marvellous – Your Senior Engineer for AI-Built Projects with 6 years of full-stack experience (including 2 years at Google). My specialty? Taking "vibe-coded" apps (Lovable, Replit, Bolt, etc.) and turning them into secure, scalable, production-ready software. I use Claude Code to ship faster with architecture that's robust, maintainable, and bug-free. I audit, refactor, and deploy it properly. I create custom n8n workflows and AI agents that automate your business. Enterprise-grade code, security best practices, built for millions. Send me a message, I'll audit your project for free....
