I will build a provider agnostic ai agent gateway for any llm API
John A
About this gig
Locked into one AI provider? One price change or outage and your product breaks.
I build a provider-agnostic gateway: ONE model name in your code, many providers behind it. OpenAI, Anthropic, Google, or a local Ollama model - swapped by config, never by rewriting code. If a provider fails or rate-limits, traffic falls over to the next one automatically.
WHAT YOU GET
- A working gateway you own and run, not a hosted black box
- Automatic fallback across providers, so an outage is not your outage
- Your workflows wired end to end and tested before handover
- Clean source code, config file, and a README a developer can follow
- Vector RAG and request logging on Standard and above
WHY ME
I ship production Python: typed, tested, documented. I do not hand over a demo notebook. Every build is verified running before I deliver it.
Message me with what you are automating and I will tell you straight whether this is the right fit, free.

FAQ
Which LLM providers can you connect?
OpenAI, Anthropic, Google Gemini, Groq, Mistral, and local models via Ollama - plus most OpenAI-compatible endpoints. You can add more later by editing one config file, no code changes needed.
Do I need to give you my API keys?
No. I build and test against my own test keys, then hand over a config file with placeholders. You add your keys yourself, so they never touch my machine.
What happens if one provider goes down?
The gateway retries and then falls over to the next provider you configured, automatically. Your app keeps working. This fallback is set up and tested as part of every package.
Can you run models locally instead of paying per token?
Yes. I can route some or all traffic to a local Ollama model on your own hardware, and keep cloud providers only as fallback. Good for privacy-sensitive data and for cutting token cost.
What do I actually receive?
Source code, a config file, a README with setup steps, and a short walkthrough. It runs on your machine or server - you own it outright, with no subscription to me.
