Building Effective Agentic AI Systems: Lessons from the Field

This repository will contain the presentation and python jupyter notebooks for my DataHack Summit 2025 conference talk, Building Effective Agentic AI Systems: Lessons from the Field. Drawing from my experience building deploying Agentic AI systems, we’ll focus on three pillars: Architecting, Optimizing, and Observability for Agentic AI Systems.

Session Details

---

Everyone is building AI agents, but how do you design Agentic AI Systems that are truly reliable in the real world?

Agentic AI systems can plan tasks, use tools, reflect on results, and even collaborate with other agents.
But building them at scale brings challenges:

• ⚙️ Choosing the right agent architecture
• 🧠 Handling memory & context efficiently
• ⚡ Reducing latency
• 📊 Monitoring and evaluating agents effectively

This session draws from my personal experience building and deploying Agentic AI systems over the past year.
We’ll focus on three pillars: Architecting, Optimizing, and Observability for Agentic AI Systems.
