♾️ Continuous Delivery & CI/CD

Shipping software isn’t the finish line; it’s the starting point of a feedback loop. I advocate for trunk‑based development with small, frequent commits so that changes are easy to review and integrate. Every commit triggers an automated pipeline that compiles the code, runs the test suite, and builds a single deployable artifact. We keep the build green; if a failure occurs the entire team stops to fix it, ensuring a stable baseline.

Our test strategy is layered. Fast unit tests run first to catch obvious regressions, followed by integration tests and end‑to‑end tests that exercise the system as a whole. Tests are run in parallel to minimise feedback time, and long‑running tests are isolated so they don’t block the pipeline. Wherever possible, we automate deployments so that the same artifact flows through staging and production, eliminating environment drift and manual error.

Reproducibility and security are fundamental. We use containerisation and infrastructure‑as‑code to ensure that development, test, and production environments are consistent. Access to the pipeline and secrets is tightly controlled; dependencies and container images are scanned for vulnerabilities, and our pipelines are versioned and peer‑reviewed. Build once, deploy many times is the mantra.

Continuous delivery is as much about culture as tooling. Teams must embrace quick feedback, collective ownership, and a bias for automation. Over time, this approach shortens lead times, reduces mean time to recovery, and improves quality by making releases routine rather than risky. High performers are proof that speed and stability rise together: the more often we deploy, the better we get at doing it safely.
