Architecture documentation
In-depth technical guides based on production systems we have built. Each playbook documents the architecture decisions, tradeoffs, operational constraints, and deployment patterns from real engineering work — written for senior engineers, architects, and technical decision makers.
AWS Lambda Production Playbook
How we design, deploy, and operate Lambda-based systems in production: the workloads where it earns its keep, the limits we have actually hit, the architecture pattern that keeps code portable, and the decisions we make before committing to the runtime.
Playwright Automated Testing Playbook
How we design, structure, and maintain Playwright test suites in production: what to test, how to keep tests independent and fast, how to manage auth state at scale, when to use synthetic data, and how to think about automated testing as a systems problem rather than a scripting exercise.
