I will build an ai powered web app or saas tool with next js and python


About this gig
Have an AI idea but need a developer to actually build it?
I build AI powered web applications and SaaS tools using Next JS, Python, and Django. Whether you need an OpenAI chatbot integrated into your platform, a smart internal dashboard that automates your workflows, or a full SaaS MVP with AI at its core, I build it clean, fast, and production-ready.
What I can build for you:
- AI chatbot or assistant integrated into your web app
- Content generator or AI writing tool with OpenAI API
- Smart internal business tool or admin dashboard
- SaaS MVP with AI functionality built in from day one
- RAG application that queries your own documents or data
- Automated workflow tool powered by LLMs
Tech stack I use:
- Frontend: Next JS, React, Tailwind CSS, TypeScript
- Backend: Python, Django REST Framework, Node JS
- AI: OpenAI API, LangChain, custom prompt engineering
- Database: PostgreSQL, vector databases for RAG
- Deployment: Vercel, Railway, Docker, GitHub Actions
You get clean source code, full deployment, and a working product from day one.
Message me before ordering. Describe your idea and I will tell you exactly what is possible and give you a clear plan.

FAQ
Do I need to provide my own OpenAI API key?
Yes. You will need your own OpenAI API key which you can get from platform.openai.com. I will integrate it into the app securely so it is never exposed on the frontend. OpenAI usage costs are billed directly to your account. I can guide you through the setup if needed.
What AI models can you integrate?
I primarily work with OpenAI models (GPT-4o, GPT-4, GPT-3.5) but can also integrate Anthropic Claude, Google Gemini, or any model with a REST API. I can also use LangChain for more complex workflows like RAG, memory, and multi-step agents.
What is a RAG application and do I need one?
RAG stands for Retrieval-Augmented Generation. It lets an AI answer questions based on your own documents, database, or knowledge base rather than just general knowledge. If you want an AI that knows your specific business data, products, or documents, you need RAG. Message me and I will tell you if
I just have an idea, no technical specs. Can you still help?
Absolutely. Most of my clients come with just an idea. Message me, describe what you want to build, and I will break it down into clear technical requirements, tell you which package fits your needs, and give you a realistic timeline and scope before you order anything.
Will the app be able to handle real users after delivery?
Yes. I build for production from the start, not just demos. Every delivery includes proper error handling, loading states, API rate limit management, and deployment to a scalable platform. The Basic package is suitable for small traffic, Standard and Premium are built to scale.

It was the first project using google colab, and delivered it without any bugs and on time. Rezwoan is very accommodative to my requests. I would give Rezwoan repeat orders.
