A personal engineering journal — long-form, first-principles explanations of the systems I'm learning to build. Backend engineering, cloud computing, AI/ML, electronics, and the strange territory between them.
Offence and defence in equal measure, from networking foundations to securing LLM applications. Built for developers who ship code and now have to secure it.
Backend EngineeringHTTP, routing, databases, caching, security — every primitive understood from the ground up. Framework-agnostic, concept-first.
DevOps & CloudLinux, CI/CD, Docker, Kubernetes, AWS, GCP, Terraform, observability — the full DevOps lifecycle, end-to-end.
JavaThe language, the JVM, the gotchas. From "what is a class" to garbage collection internals — the way I wish someone had taught me.
High-Level System DesignHow big systems are designed — CAP, consistency, sharding, queues, microservices, classic interview designs. Pattern-by-pattern from first principles.
Transformers, embeddings, agents, RAG, evals — what's actually happening under the API call, and how to build with it.
Voltage, current, op-amps, microcontrollers, PCB design. Bridging the gap between software and the physical world.
