About this gig

Full stack web app developer Claude Code AI development SaaS platform custom website React Node.js MVP


Stop waiting months for a custom app. Get it built in weeks without sacrificing quality.


I'm a Senior Full-Stack Engineer (Ex-Google) with 6 years of experience. I use Claude Code + AI tools to accelerate development, so you get a production-ready app at lightning speed without the buggy "vibe coding" mess.


What you get:

  • Fully Custom Web App SaaS, dashboards, marketplaces, or internal tools.
  • Clean, Scalable Code Enterprise-grade, not AI-generated chaos.
  • Modern Stack React, Next.js, Node.js, Python, Supabase, Firebase, or your choice.
  • Secure & Performant Best practices, optimized, error-proof.
  • Full Deployment Vercel, Render, AWS, or your preferred platform.


How we work:

  1. Share your idea (rough sketch is fine).
  2. I build a prototype in days.
  3. We iterate until perfect.
  4. I deliver a polished, deployed app ready for users.


Why me over a junior? Speed without quality is just debt. I combine AI acceleration with 6 years of senior engineering for apps that are fast, beautiful, and built to last.

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.
