Christopher Diaz, senior engineering leader at RVO Health, explores how platform engineering can thrive in a large-scale, multi-business-unit organization. Drawing from his experience supporting over ten distinct business units, Diaz demonstrates how to drive value through foundational capabilities without requiring a fully mature internal developer platform from day one. The talk highlights how documenting existing tools, assessing current capabilities, and leveraging feedback loops can help align platform engineering efforts across varied teams. Diaz also shares practical strategies for getting started in environments with heterogeneous tech stacks and evolving requirements. Tools like Backstage are featured as examples of how to unify developer experiences across business units. Attendees will leave with actionable insights on incrementally introducing platform engineering practices within complex organizations, while aligning with both team-level and company-wide goals.
