Design enterprise AI solutions and agentic architectures, including RAG capabilities, voice-based agents, intelligent automation, multi-agent systems, orchestration patterns, and Human-in-the-Loop processes.

Guide architecture decisions across Microsoft AI technologies such as Copilot Studio, Azure AI Foundry, Azure OpenAI, and modern AI development frameworks.

Remain hands-on through prototyping, proof-of-concepts, technical reviews, and key implementation decisions, defining approaches for MVP delivery, production deployment, and solution scaling.

Define AI testing, evaluation, monitoring, quality assurance, and success measurement approaches.

Collaborate with governance, security, and risk teams to ensure compliance with enterprise standards and responsible AI requirements.

Support solution shaping, technology selection, effort estimation, and technology adoption decisions, including evaluation of emerging AI capabilities and platforms.
