Why End-to-End Testing Fails in Microservice Architectures (Fri, 20 Feb 2026)
End-to-end testing is often described as the ultimate safety net for modern software systems. In theory, it validates real user workflows across all components and ensures that the system behaves correctly as a whole. In practice, however, end-to-end testing frequently fails to deliver reliable value in microservice architectures. Teams invest heavily in E2E suites, only to face slow pipelines, flaky tests, and low confidence in test results.

Queueing Theory for LLM Inference (Fri, 20 Feb 2026)
If you are deploying LLM inference in production, you are no longer just doing machine learning. You are doing applied mathematics plus systems engineering. Most teams tune prompts, choose a model, then wonder why latency explodes at peak traffic. The root cause is usually not the model. It is load, variability, and the queue that forms when the arrival rate approaches the service capacity.

From Prompts to Platforms: Scaling Agentic AI (Part 2) (Thu, 19 Feb 2026)
The tenets I introduced in Part 1 covered the functional mechanics — the core features that power an AI platform. But in production, functionality is only half the battle. These next six Operational Tenets are about how the platform survives the chaos of the real world and scales without breaking under its own complexity. Here are the pillars critical to operating an AI platform at scale:
