Agentic AI Engineering in Practice: How AI Engineers and Forward-Deployed Engineers Build with Claude Code, Codex, and Gemini

A practical, three-tool guide to the AI-native software development life cycle (SDLC): Plan, Design, Build, Test, Deploy, Maintain, reimagined for agentic coding. In March 2025, a small nonprofit research group called METR published a chart that made many engineering leaders sit up straighter than usual. Working backward through six years of model releases, METR measured […]

Claude Code Observability with OpenTelemetry

Agentic coding tools like Claude Code, OpenAI Codex, Google Antigravity, and Cursor have become ubiquitous for everyday software development. As agentic systems mature, much of the work developers have them do is delegated, one subagent at a time. Many teams are also exploring and using a shared, multi-tenant Agentic Infrastructure, where cost isn’t tied to […]

How to Build AI Systems That Know When They Don’t Know: A Practical Guide

Large Language Models (LLMs) have fundamentally changed how we build internal business applications. They allow developers to create intelligent software that can synthesize complex corporate data, answer internal queries, and automate repetitive workflows. But moving an LLM application from a local prototype to a production enterprise system can reveal a critical reliability issue: overconfidence. Standard […]

How AI Chips Are Made

We just published a comprehensive, first-principles course on the semiconductor supply chain on the freeCodeCamp.org YouTube channel. Taught by hardware specialist Kian Kyars, this deep dive explains the complex journey of an AI accelerator from raw silicon all the way to modern data center deployment. As capital expenditure on AI infrastructure increases into the hundreds […]

How OpenTelemetry Works: A Complete Guide

If you’re a software developer or DevOps engineer, you’ve probably come across OpenTelemetry. It comes up a lot, especially when talking about observability, monitoring, or debugging distributed systems. You might even know the basic definition, but knowing what OpenTelemetry is vs how it actually works are two different things. By the end of this guide, you’ll […]
