This workshop offers a deep dive into Gemini CLI/GCA’s capabilities, integrations, and real-world applications across diverse engineering environments. Participants will explore how AI can augment developer workflows, streamline testing, and accelerate delivery — all within a secure, collaborative framework. This session will help developers, architects, and DevOps engineers understand how to leverage GCA in real-world projects, from brownfield modernization to greenfield builds driven by Test-Driven Development (TDD).
