The era of manual refactoring is ending. As we move toward the 2026 technical landscape, the role of the developer is shifting from code author to orchestrator of agentic AI systems. This session aims to provide a comprehensive roadmap for transforming legacy .NET Framework and Java Spring monoliths into secure, cloud-native architectures.

We begin by demonstrating how to use LLMs as "Architectural Partners" with agentic coding solutions like CoPilot, AWS Transform to identify bounded contexts and automate the heavy lifting of refactoring. Next, we dive into AI-first API design patterns, exploring how to manage the token math, streaming protocols, and observability required for modern backend services. We then explore the synergy between AI and Event-Driven Architecture, showing how reactive intelligence can lead to massive cost savings and unprecedented scalability. Finally, we harden our application against the OWASP Top 10 for LLMs, addressing risks like Prompt Injection and Excessive Agency through defensive design and human-in-the-loop strategies.

This session delivers the blueprint for the next generation of software engineering.
