<li>Develop high-performance Python backends (FastAPI or Flask) to serve AI features to our global user base.</li>
<li>Build robust evaluation frameworks to measure LLM accuracy, reduce hallucinations, and monitor production performance using tools like&nbsp;LangSmith&nbsp;or&nbsp;Arize Phoenix.</li>
