About this gig
Cut your OpenAI and Claude API costs without losing quality.
Is your AI feature live, but the monthly API bill is growing faster than your revenue? I audit your LLM usage, find exactly where the money goes, and fix it.
Common cost problems I find and fix:
- Using expensive models for simple tasks
- Sending the same long prompts again and again (no caching)
- Unlimited output tokens and bloated prompts
- Hidden retry loops that multiply your costs
- Real-time calls for jobs that could run in cheaper batches
What you get:
- A clear report showing cost per feature and model
- Model routing: cheap models for simple tasks, strong ones where it matters
- Prompt caching and batch processing where they fit
- Before and after cost comparison, with quality checked
Why me: I build production LLM systems where I select models for cost and latency, and design validation and retry logic, for clients in the USA, Europe and the Middle East.
Works with: OpenAI, Claude, Azure OpenAI, Gemini, DeepSeek, Mistral, LangChain
Message me with your monthly AI spend and I'll tell you where savings are likely.

FAQ
How much can I save?
It depends on your app, so I don't promise fixed numbers. The Basic audit shows you exactly where the savings are before you invest in changes. Apps using one expensive model for everything usually have the most room to save.
What access do you need?
Your usage data (an export from the OpenAI or Anthropic dashboard, or your logs) and read access to the code that makes AI calls. I never need your API keys pasted in messages.
Will cheaper models make my AI answers worse?
Not if it's done carefully. I only move tasks where a cheaper model performs just as well, and I test quality before and after. Important tasks stay on strong models.
Which providers and frameworks do you support?
OpenAI, Claude, Azure OpenAI, Gemini, DeepSeek, Mistral and open-source models, in Python or Node.js apps, including apps built with LangChain.
What's the difference between the packages?
Basic is an audit and savings plan. Standard adds me implementing the top savings with before/after proof. Premium adds a gateway with cost tracking per feature, budget caps and automatic fallbacks.
Will you break my app while making changes?
No. I work on a separate branch, test every change, and you review before anything goes live.
Can you also make my AI app faster?
Often, yes. Smaller models, caching and shorter prompts usually reduce response time as well as cost. I'll note speed improvements in the report.
What happens after delivery?
You get 7 days of support for my changes. As usage grows, the Monthly review extra keeps your costs in check for 30 days.
