• Integrate applications with Azure OpenAI and other LLM-based services.
• Design effective prompts and reusable prompt patterns using advanced prompt engineering techniques.
• Build scalable backend services and REST APIs using Python and FastAPI.
• Develop evaluation and observability mechanisms for measuring AI response quality, latency, reliability, and retrieval effectiveness.
• Use LangSmith for tracing, evaluation, debugging, and observability of LLM/agent workflows.
• Containerize and deploy AI services to Azure Kubernetes Service (AKS).
• Design solutions using appropriate Azure services for identity, security, networking, storage, monitoring, and application integration.
• Implement production-ready practices including exception handling, logging, retries, API security, configuration management, and observability.
• Work closely with product owners, architects, and engineering teams to convert business requirements into scalable AI product capabilities.
• Participate in architecture/design reviews, code reviews, testing, deployment, troubleshooting, and ongoing product enhancement.
• Evaluate emerging LLM, retrieval, agentic AI, and AI engineering techniques and apply them where they provide measurable product value.
