Spec Driven Development: When Architecture Becomes Executable

Spec-Driven Development inverts traditional architecture by making specifications executable and authoritative. It transforms declared intent into validated code through AI generation and provides architectural determinism. It eliminates drift through continuous enforcement, but demands new engineering discipline in schema design and contract-first reasoning.

Holistic Engineering: Organic Problem Solving for Complex Evolving Systems

Vanessa Formicola discusses how "invisible" forces shape our code and architecture. She shares patterns like "Cirque du Soleil coding" and "Shared Kitchen Sinks," explaining why technical problems often have social roots. Architects and leaders will learn how to use Social Decision Records (SDRs) and holistic modeling to make the implicit explicit and drive success.

Platform-as-a-Product: Declarative Infrastructure for Developer Velocity

Declarative infrastructure config hides complexity, enabling developers to focus on application code. Unified YAML per service allows early cost validation, while independent CI with centralized CD balances team autonomy and deployment consistency. This standardized approach scales across organizations, making infrastructure invisible and operations automatic.
