Software Architecture, Security, and Delivery Systems
Reliable software depends on clear architectural reasoning, automated security, continuous context across tools, and delivery practices that scale beyond one platform.
Summary
An architecture narrative turns diagrams into a business-centered story covering constraints, decisions, trade-offs, alternatives, risks, and a three-act structure of setup, confrontation, and resolution. Security requires automated coverage across hardware, dependencies, platforms, governance, cryptography, and agent identities, with CHERI, software bills of materials, AI-assisted testing, and post-quantum migration addressing different layers. Development work now crosses IDEs, CLIs, pipelines, cloud machines, and communication tools, making context preservation and coordinated automation central challenges. Heroku established one-command deployment, buildpacks, disposable dynos, free hosting, and Twelve-Factor practices, while its move to sustaining engineering in February 2026 shows how its ideas outlasted its closed platform model.
