This review cycle reflects what we’ve learned from a recently delivered project and a broader re-check of our direction. We’re promoting a few technologies that proved themselves in practice, adding several tools we actively used, and tightening recommendations where our experience showed clearer “default” choices. In parallel, we revisited our infrastructure approach, which led to updates around orchestration, IaC, and deployment patterns.
