The Economics of CI/CD: What Slow Pipelines Are Really Costing You

DevOps

Slow CI/CD pipelines are rarely treated as a financial problem—they're dismissed as "technical debt" or a developer experience issue. However, this outline reframes pipeline speed as a capital allocation question: every minute engineers spend waiting for builds, tests, or deployments is measurable cost.

CICD

Common CI/CD Anti-Patterns (and How to Fix Them)

DevOps

Most engineering teams claim to practice CI/CD but have instead automated the form without adopting the discipline. This article names the most common structural anti-patterns that corrupt CI/CD pipelines — turning them into slow, untrustworthy, or cosmetic processes — and provides evidence-backed remedies for each. The target reader is a mid-to-senior engineer or engineering lead who has inherited or built a pipeline they suspect is lying to them.

JSON Schema Evolution with Spring Kafka and Confluent Schema Registry

Data Engineering

Schemas and schema registries are the governance tools that ensure vitality of data communications through configurable compatibility guardrails as patterns and rules to evolve schemas in a controlled fashion. In this article I will demonstrate how Confluent Schema Registry can be used in conjunction with JSON Schema to govern and enforce rules for schema evolution in the default backwards compatibility mode.

Todos REST API with MuleSoft and AWS DynamoDB

MuleSoft

In this article I present a walk through of the connonical Todos REST API which utilizes AWS DynamoDB to store todos and exposes Create, Read, Update, and Delete (CRUD) interfaces to manage todos implemented with MuleSoft's Anypoint Platform. DynamoDB is a fully managed No SQL document database provided by AWS with millisecond latency at any scale with proper data modeling. MuleSoft is the complete platform for integration and APIs.
