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.

Achieving a Culture That Works: Inclusive Leadership that Drives Lasting Success

Matthew Card discusses the intersection of leadership and inclusivity at the BBC. He explains how "changing the bar" rather than just raising it can transform team dynamics. Covering trust, psychological safety, and his "C.A.P.S." and "D.O.S.E." frameworks for resilience, he shares practical strategies for engineering leaders to eliminate toxic behaviors and empower diverse talent to thrive.

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.
