About this gig
Build your AI SaaS app or MVP with Next.js, Claude Code and Supabase
Your AI SaaS idea deserves more than broken code and missed deadlines.
Stuck deploying your Next.js app on Vercel? Drowning in API errors? Built something on Lovable or Replit that's hit its limits? I've worked with founders and startup teams facing every one of those problems. You're in the right place.
I build full-stack AI SaaS apps, MVPs, CRMs, and internal tools using Next.js, Claude Code, and Supabase deployed live on Vercel.
What I deliver:
- AI SaaS apps and MVPs with Next.js + Claude Code
- Claude API, OpenAI, and custom LLM integrations
- MCP server and third-party API connections
- Supabase backend (auth, database, edge functions)
- Vercel deployment live production URL
- Migration from Lovable, Replit, or Base44
- Next.js bug fixing and code rescue
- CLAUDE.md and advanced prompt engineering
Who this is for:
- Founders building an AI MVP who need it live fast
- Startup teams with broken or stalled builds
- Non-technical individuals who need hands-on support
Clean code. Real deployment. No surprises. No disappearing acts.
Message me before ordering I'll tell you exactly what I need to bring your vision to life.

FAQ
What is Claude Code and how do you use it for AI development and vibe coding?
Claude Code is Anthropic's AI tool that writes and runs code autonomously. I use it with a vibe coding workflow to build full-stack AI SaaS apps and MVPs faster, cleaner, and at a fraction of agency cost.
My Lovable app or Replit build is broken or not production-ready. Can you fix or migrate it?
Yes, Lovable and Replit apps often have broken auth and exposed API keys. I migrate your build into a clean Next.js + Supabase codebase, fix every gap, and deploy it on Vercel so it works for real users.
Can you build AI agents or add workflow automation and AI automation to my app?
Yes, AI agent development and workflow automation are core to every build. I use Claude AI, OpenAI, and n8n automation to create agents that reason and automate real business tasks, not just respond to prompts.
I'm not technical. Can you still build my AI web app or SaaS product?
Absolutely, many clients are non-technical founders. You describe what your AI web app should do, I handle all AI development, and update you in plain language. My Basic package includes Claude Code training so you can manage your app going forward.
Will my AI SaaS app be secure and production-ready for real users?
Yes, every build includes Supabase Row Level Security, proper authentication, and no exposed API keys as a baseline. This is what most Lovable and no-code saas development builds skip, and why those apps fail with real users.
Can you integrate Claude API, OpenAI API, or build an AI chatbot for my app?
Yes, Claude API, OpenAI API, and AI chatbot development are in Standard and Premium packages. I also handle Claude MCP setup for advanced AI integration connecting your app to external data sources and live APIs.
Can you set up Claude Code for my project and train my team to use it?
Yes, my Basic package covers full Claude Code setup, a custom CLAUDE.md file, and a 30-minute vibe coding training session. Perfect for developers or startup teams who want to handle their own AI coding going forward.
Can you build n8n automation or AI automation workflows for my SaaS?
Yes, n8n automation and AI automation workflows are in my Standard and Premium packages. I design and deploy workflow automation that runs in the background and wire it directly into your Next.js AI web app.
My Next.js app or AI web application is stuck or broken. Can you rescue it?
Yes, I handle Next.js project rescue regularly. Bugs, Vercel deployment errors, broken APIs I fix them cleanly. I work with apps from Lovable, Replit, and other saas development platforms. Message me to describe the issue first.
