Vinny Carpenter has spent more than thirty years building software and leading engineering work across platforms, systems, and the long handoff between idea and production.He writes at vinny.dev about software, AI, platform engineering, engineering leadership, and the operating models that make teams better after the tool demo ends. His recent work focuses on agentic software development, spec-first delivery, and the human bargain behind automation.The Bottleneck Is Never the Stack grew out of that public writing practice: a year of essays sharpened into one argument about intent, judgment, standards, and trust.
