About this gig
Need a production-ready AI SaaS application built fast?
I'm a full-stack engineer with 4+ years shipping AI-powered web apps using Next.js, OpenAI, Claude, and Stripe.
I build complete SaaS platforms from scratch: authentication, subscription billing, AI features (chatbots, RAG systems, content generation), and a polished dashboard all in one connected codebase.
What you get:
- Full-stack Next.js app (frontend + backend API)
- OpenAI integration (GPT-4, embeddings, RAG pipelines)
- Stripe subscription billing with webhooks
- PostgreSQL/MongoDB database with clean schema design
- User authentication & multi-tenant architecture
- Docker setup + deployment on AWS, Vercel or VPS
- Full source code + setup docs, no hidden extras
Why work with me:
I don't just wire up APIs I design systems that scale. My background includes multi-tenant SaaS architecture, vector search with embeddings, and CI/CD with GitHub Actions, so your app is demo-ready and production-stable from day one.
Message me with your idea before ordering, and I'll map out the exact scope and timeline for your project.

FAQ
Do you use pre-built templates or custom code?
Everything is custom-built for your project — no generic templates. I design the architecture, database schema, and AI integration around your specific use case, so the app is unique and scalable from day one.
Can you integrate a different AI model besides OpenAI?
Yes. I also work with Claude, Gemini, and open-source models (Llama, Mistral), plus vector databases like Pinecone or pgvector for RAG pipelines. Just tell me your preferred stack before ordering.
Will I receive the full source code?
Yes, you own 100% of the code. I deliver a clean, documented repository with setup instructions, an environment variables template, and deployment steps for AWS, Vercel, or your preferred host.
How do you handle Stripe subscription billing?
I implement Stripe Checkout or Billing with webhook handling for upgrades, downgrades, cancellations, and failed payments — fully tested in Stripe's test mode before going live
What if my project needs more than the listed packages?
Message me with your requirements and I'll send a custom offer, scoped by feature complexity and timeline — fair pricing whether it's a small MVP or a full enterprise build.

Mehedi did a great job with the chatbot. He pushed all the clean code directly to my GitHub repo and handed everything over without any issues. Super easy to talk to and very helpful. Thanks again!
