3 Tips for AI Code Review That Doesn't Suck
April 14, 2026
AI code review sounds great in theory. In practice, most teams just end up with more noise in their merge requests. In this article, I share 3 steps that made AI code review actually useful in my team and also reasonably priced (under $1.50 per review).
Python Development Workflow for AI era
April 8, 2026
AI made coding faster. But faster code without a fast feedback loop is just faster chaos. If we can code faster, we need everything around it to keep up: pipelines, testing, deployments, and monitoring. In this article, we break down a Python development workflow designed for shipping reliably in the AI era. Four pipelines. Three environments. Small MRs, you're willing to throw away. Deployments that are non-events. This is the first in a series where we'll dig into each step - from automated pipelines to feature flags to monitoring that catches issues before your customers do.
