I will integrate openai or claude API into your existing app

Want to add AI to your existing app without rewriting it?

I integrate LLM APIs (OpenAI, Claude) into Python and FastAPI applications as clean, separate modules or endpoints, so your existing code stays safe. I also connect your app to third-party APIs and webhooks.

WHAT I BUILD

- AI features: summarizer, classifier, text generation, assistant endpoint

- Prompt engineering and structured JSON outputs

- Streaming responses

- Error handling, retries, and rate-limit handling

- Third-party API and webhook integration with async handling

- README so your team can maintain it

HOW COSTS WORK

You use your own API key, so AI usage costs go straight to your provider account and stay transparent.

WHAT'S NOT INCLUDED

Frontend, model training or fine-tuning, cloud deployment, and payment gateways. Message me if you need these.

HOW IT WORKS

1. Message me with your app and the AI feature you want.

2. I confirm scope and package.

3. I build, you review, I revise within your package limit.

Please message me before ordering.
