Mercy
About this gig
HELLO AMAZING BUYER,
AI applications can look good in testing but fail with real users. If your LLM app, AI agent, chatbot, or RAG system gives inconsistent answers, fails edge cases, uses tools incorrectly, or has no reliable way to measure performance, I can help.
I will set up, test, debug, fix, and improve your AI evaluation workflow. I can work with existing AI applications or evaluation systems to identify failures, create meaningful test cases, improve grading logic, and help you measure results across prompts, models, agents, tools, and RAG pipelines.
Services include AI eval setup, LLM testing, agent evaluation, regression testing, prompt comparison, dataset creation, automated scoring, LLM-as-a-judge workflows, RAG evaluation, debugging failed evals, fixing unreliable evaluation logic, and performance reporting.
I work with Python, TypeScript, Node.js, Next.js, APIs, PostgreSQL/Supabase, Cursor, Claude Code, Replit and modern AI development tools.
Whether you need to fix existing AI evals or improve your AI application's reliability, send me your requirements before ordering and I'll recommend the right solution. CONTACT ME NOW!!!

FAQ
What are AI evals?
AI evals are structured tests used to measure how well an AI system performs. They can test answer quality, accuracy, tool use, RAG retrieval, agent behavior, prompt performance, and other expected behaviors
Can you fix my existing AI evaluation system?
Yes. I can review your existing eval code or workflow, identify unreliable tests, grading problems, broken logic, or inconsistent results, and improve the system where technically feasible.
Do you only work on new AI applications?
No. I can work on existing AI agents, chatbots, LLM apps, RAG systems, and evaluation pipelines that need testing, debugging, fixing, or improvement.
What do you need to get started?
Please provide your source code or repository access where appropriate, a description of the AI system, your current eval setup, sample inputs/outputs, known problems, and your expected behavior or success criteria.
Can you compare different prompts or AI models?
Yes. I can help create structured test cases and evaluation criteria to compare prompts, models, or versions of your AI system and identify measurable differences in performance.
