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

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.

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.

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

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.

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.
