Perspectives on software quality, performance engineering, and AI-driven development.
A comprehensive testing guide for Model Context Protocol servers: JSON-schema validation, JSON-RPC contracts, SDK behaviour tests, and security boundaries.
A practitioner's guide to testing WAF rules, OWASP CRS anomaly scoring, and rate limits in CI: attack matrices, false-positive safety, and k6 verification.
A practitioner's guide to testing RAG systems: measuring Recall@k, MRR, and nDCG with NumPy, hybrid search validation, grounding verification, and CI regression gates.
A practitioner's guide to testing non-deterministic LLM applications: parameter pinning, structured schema invariants, calibrated rubrics, and binomial confidence intervals in CI.
A practitioner's guide to automated WCAG 2.1 AA auditing in CI: @axe-core/playwright stateful scans, baseline debt suppression, impact triage, and manual audit boundaries.
Why 100% line coverage still lets critical defects escape into production. A practical deep dive into mutation testing, property-based invariants, API fuzzing, and consumer-driven contracts with Pact.
A comprehensive guide to high-velocity test automation: Boehm's cost law, flaky test mathematics, ephemeral container orchestration with Docker/WireMock, and matrix sharding for sub-5-minute CI feedback.
A first-principles guide to enterprise performance engineering: queueing theory, Little's Law, Gunther's Universal Scalability Law, multi-tier saturation modeling, and k6 threshold automation.
