About Core Routers
Engineering credibility should be inspectable.
Core Routers is an independent lab for studying the behavior of distributed and AI-backed systems under realistic failure and scaling conditions.
The site is intentionally organized around evidence rather than opinion. Labs state the failure scenario, instrumentation, hypotheses, competing fixes, and measurable outcomes. Field notes capture narrower architecture judgments and operating heuristics.
The commercial side follows the same pattern: bounded reviews, written findings, explicit assumptions, and implementation only when the evidence supports it.
Coverage
Distributed systems, Java/Spring production systems, Kafka, Cassandra, backend performance, observability, cloud architecture, RAG/agent reliability, and production AI infrastructure.
