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.
HTTP, 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.
