May: AI on both sides of the diff, browser tests as state guardrails, MCP as production integrations
Three threads from the month. The honest tension of using one AI vendor for both codegen and review, browser-test-as-code (Playwright at PR time plus Checkly and Datadog as synthetic monitoring) becoming the practical guardrail against AI-introduced regressions in stateful systems, and MCP servers maturing into the agent runtime's SDK layer without the operational discipline that usually carries.

April: Agentic engineering in production, AWS wired in Terraform, benchmarking SCA tools
Three threads from the month. The agentic workflow stack moving from sketch to production (gh-aw source/lock split, MCP versioning, network firewall), AWS dev environments wired end-to-end in Terraform with Fargate Spot pulling most of the cost out, and a tour through the SCA tool market that turned into a complaint about how vendors run technical evaluations.

March: PKI before the mid-2026 deadline, an agentic engineering setup, and infra hygiene at scale
Three threads from the month. The Chrome root program splitting serverAuth from clientAuth and what that means for internal authentication, formalizing how I run multiple coding agents in parallel without them stepping on each other, and a sweep through the boring infra hygiene that quietly stops working at scale.
