About the channel
The Hot Path — system design, explained in depth. How real systems are actually built and scaled: the architecture, the trade-offs, and the decisions that matter. Each video reasons through a problem from first principles to production reality — the parts most explainers skip — with a recurring focus on AI / LLM systems (RAG, agents, inference infrastructure) alongside the classic distributed-systems foundations (caching, queues, consistency, scaling). If you build backends, distributed systems, or AI infrastructure and you want depth over hand-waving, subscribe. New videos weekly.
