Connect to your AI
I will fix and improve your openai or claude ai integration
Chris Hellon
About this gig
Is your AI feature giving wrong answers, running slowly or costing too much?
I'm a senior .NET developer with 17 years of experience, and I build and maintain production AI features with the OpenAI and Claude APIs.
Common problems I fix:
- Inconsistent or made-up answers Broken or unreliable JSON output
- Slow responses and timeouts API bills higher than they should be
- Prompts that only work some of the time
- No handling for errors, limits or bad input
How I fix them:
- Clearer prompts, with examples and fixed output formats
- Structured outputs your code can trust
- Caching, the right model for each task, and spend limits
- Test sets, so you can see accuracy before and after
I work in C# and .NET, and in JavaScript or TypeScript. Not sure what's wrong? Start with the Health Check: you'll get a clear written list of fixes, whoever makes them.
Message me before ordering with what's going wrong and an example.

FAQ
Do you need access to my code?
For Standard and Premium, yes, through GitHub, Azure DevOps or a zip file. For the Health Check, the relevant files and some example prompts and outputs are enough.
Will you need my API key?
Only for testing, and only a limited key you can delete afterwards. Never send your main key.
Can you guarantee 100% accuracy?
No one honestly can with AI. I’ll measure accuracy before and after against real examples, so you can see the improvement.
My app is in Python. Can you help?
The Health Check works for any language. For code fixes, I work in C#/.NET and JavaScript/TypeScript.
