Developer Experience as a Measurable Outcome

Your platform team can’t improve what it doesn’t measure. Here’s the metrics stack that separates signal from vanity.Part 7 of my series on Platform Engineering. Last time, we covered platform team topology and operating models and how to organize humans around platform ownership. This time: making developer experience a measurable outcome instead of a feeling. Follow along for more platform engin...

Amazon Bedrock Agents Orchestrating Google ADK over A2A

This article explains how to build and test a cross-cloud currency agent. An Amazon Bedrock master agent, built with Strands Agents and hosted on Amazon Bedrock AgentCore Runtime in AWS us-east-1, delegates to a Google ADK worker on GCP Cloud Run in us-central1 over A2A v1.0. The master cross-checks the worker against an MCP exchange-rate tool and measures the latency, reliability, and failure beh...

Montando um Cluster Kubernetes On-Premise — Parte 6: Deploy, Atualização e Escalabilidade de uma Aplicação Própria

🇺🇸 English version coming soon. Na Parte 5 desta série, validamos o cluster de ponta a ponta fazendo o deploy do Nginx. Agora vamos um passo além: construir a imagem Docker de uma aplicação própria, publicá-la, colocá-la para rodar no cluster e explorar operações do dia a dia — atualização de versão, rollback e escalabilidade (manual e automática). Como exemplo, foi utilizada uma API REST simple...

Validating JSON Payloads Against a Schema Before They Hit Your Service

A schema is only useful if it actually catches bad payloads before they reach your handler. Most teams write the schema, then forget it during local development, or only enforce it in CI on a handful of fixtures. That gap is where the 2 a.m. incident starts. This walkthrough is about the boring, repeatable discipline of validating JSON at the boundary — in your editor, in a pre-commit hook, and in...

AI Made Code Review the Bottleneck. Attach the UI to Your PR

You open a frontend pull request. The diff is 400 lines, an AI agent wrote most of it, and the description says "adds the checkout flow". CI is green. You read the diff. It looks reasonable. You still have no idea what the UI actually does. So you do what you always do. You pull the branch, install dependencies, start the dev server, and click through the flow yourself. Ten minutes later you ap...
