• AI Orchestration: Build robust prompt-chaining strategies and agentic workflows that integrate LLMs into our SaaS application.
• System Reliability: Monitor agent behavior and system-level metrics in Go to identify and mitigate hallucinations or performance degradation.
• Cross-Functional Leadership: Take technical ownership of AI initiatives, leading collaboration across BE/FE/SRE teams to drive system-level decisions.
• Optimization: Bridge the gap between Python-based AI research and Go-based production environments, ensuring seamless model serving and data flow.
