I will build your production saas mvp with full stack and ai integration


About this gig
You need a SaaS product or MVP built properly not a tutorial clone, not a proof of concept that breaks the moment a real user touches it.
Whether you have a validated idea, an existing codebase that needs a real engineer, or an AI feature that needs to actually work in production that is exactly what I build.
WHAT I BUILD
- Full stack SaaS: Next.js, React, Node.js, Express, REST and GraphQL APIs
- Databases: PostgreSQL, MongoDB, Supabase, Firebase, Prisma ORM
- AI and LLM integration: OpenAI, Claude, Gemini, Mistral, RAG pipelines, agents, streaming, function calling
- Auth systems: JWT, OAuth, magic links, role-based access, multi-tenancy
- Payments: Stripe subscriptions, usage-based billing, webhooks, customer portal
- Deployment: Vercel, Railway, VPS, Docker Full source code with documentation
WHAT YOU ACTUALLY GET
- Production-ready code, not demo quality
- Auth, error handling, and edge cases handled from the start
- A codebase your next developer can read, extend, and build on
WHY THIS IS DIFFERENT
- Stack chosen for your project
- No disappearing after delivery
- Problems flagged before they become blockers, not after your deadline

FAQ
What does MVP mean and what's included?
A working, deployed product with your core features built for real users not a demo. Every delivery is production-ready from day one.
Can you add AI features to an existing app I already have?
Yes. Adding OpenAI, Claude, or Gemini API integration to an existing Next.js or Node.js app is a common request. Message me with your codebase details and I'll confirm what's possible.
Do you handle design or just the code?
I can work from Figma files or build a clean professional UI using Tailwind and shadcn/ui. If you have no design, I handle it as part of the build.
What about after I launch can you maintain it?
Yes. I offer monthly maintenance retainers for bug fixes, feature additions, and dependency updates. Many clients continue working with me after delivery as their product grows.
Is the AI feature included or is it extra?
LLM API integration (OpenAI, Claude, or Gemini) is included in Standard and Premium packages. Basic package covers the app structure and can be upgraded later.
