Enterprise AI teams moving from proof-of-concept to production frequently search to hire a freelance LLM evaluation, Ragas, DeepEval, Arize Phoenix & LangSmith programmer to measure and eliminate hallucinations, tool-call failures, and prompt regressions. I am Aldian Fazrihady, a Senior Freelance AI Application Engineer and Full Stack Programmer available via Upwork.
Core LLM Evaluation & AI Observability Capabilities
- Automated Golden Dataset & CI/CD Evals: Building deterministic and LLM-as-a-Judge evaluation pipelines with Ragas, DeepEval, Promptfoo, and LangSmith to score faithfulness, context recall, answer relevance, and tool-selection accuracy on every pull request.
- OpenTelemetry & Production Tracing: Instrumenting LangGraph, Google ADK, and OpenAI/Anthropic SDK workflows with Arize Phoenix, Langfuse, and LangSmith to trace token latency, cost per tenant, and retrieval quality in real time.
- Red-Teaming & Prompt Injection Guardrails: Auditing AI agents against adversarial jailbreaks, indirect prompt injections, and PII leakage.
Frequently Asked Questions
How do we stop prompt or model changes from breaking existing AI features?
I curate a 100+ scenario golden evaluation dataset from real production edge cases and wire automated regression gates into GitHub Actions so any drop in faithfulness or JSON schema compliance blocks deployment.
