Systems | Development | Analytics | API | Testing

Both methods have their place, but identity passthrough is the go-to for modern, secure, and compliant data access.

Self-service analytics lets SaaS operators ask a business question and get a trusted, metric-backed answer without waiting on an analyst. Here’s what that requires in practice.

For teams using CI/CD, the specs of the build machine can have a significant impact on development productivity. Faster builds mean shorter fix-and-verify cycles, which speed up the overall development process. However, it’s hard to know how fast each CI/CD service actually is without comparing them under the same conditions. In this article, I compare the iOS build speeds of GitHub Actions, Bitrise, and Codemagic using the same Flutter project, and compare them in terms of cost-performance as well.

Most teams already know a lot about production. They have dashboards. They have traces. They have alerts. They have enough telemetry to explain what happened after an incident and enough graphs to argue about it for the rest of the week. Then they go to test a change and start from scratch. The integration tests hit a hand-written mock that returns {"status": "ok"}. The load tests replay a CSV somebody exported months ago. Staging is close enough to production right up until it matters.

Automated regression testing is no longer just about rerunning test cases after every change. In modern systems, it’s about ensuring that rapid releases, distributed architectures, and constant updates don’t silently break existing functionality. As teams move faster, the real challenge is not running more tests, but running the right ones efficiently.
