I will integrate ai into your saas app using openai, anthropic, or gemini apis


About this gig
You've probably tried pasting your OpenAI key somewhere and watching it break. Or maybe you got a basic chat working but it has no memory, no context, and no real use to your actual users. That's where I come in.
I've spent the last two years integrating LLMs into real products not demos. I know where the token limits bite, how to structure prompts so they don't drift, and how to build streaming UIs that feel snappy instead of frozen.
Tell me what your app does and what you want AI to do inside it. I'll figure out the right approach whether that's a RAG setup connecting to your own data, a multi-turn assistant with proper memory, or a smart feature like auto-summarization or classification built into your existing workflow.
What I'll build for you
- Full LLM API integration OpenAI GPT-4o, Anthropic Claude, or Google Gemini
- Streaming responses with real-time UI (no frozen spinners)
- Prompt engineering with context management so the AI stays on topic
- RAG pipeline connect AI to your database, docs, or knowledge base
- Conversation memory and session handling
- Clean API layer between your frontend and the LLM
- Unit tests and documentation so you can maintain it after delivery

FAQ
Do I need to already have a backend?
For Basic, yes — I'll integrate into an existing Node.js, Python, or similar backend. For Standard and Premium I can build the integration layer from scratch if needed.
Which AI model do you recommend?
Depends on your use case. GPT-4o is the most versatile. Claude is better for long documents and reasoning. Gemini has strong multimodal support. We'll figure out the right fit during our first conversation.
