Caching Layers: From HTTP to the Database
Design coherent browser, CDN, application, distributed, query, and database caches without trading speed for stale data or outages.
How Type Inference Actually Works
How TypeScript gathers constraints, solves type variables, widens literals, narrows control flow, and decides when inference must stop.
Domain-Driven Design: Bounded Contexts Explained
Bounded contexts turn one overloaded business model into explicit languages, ownership boundaries, and dependable integration contracts.
Prompt Engineering as Software Engineering
Treat prompts as versioned, typed, tested production artifacts with explicit contracts, evals, observability, and security boundaries.
How a Compiler Turns Code into Machine Instructions
Follow a tiny typed compiler from tokens and ASTs through SSA-like IR, optimization, register allocation, machine code, and linking.
Bloom Filters: Probabilistic Membership at Scale
Learn how Bloom filters trade a controlled false-positive rate for compact, fast membership checks across caches and databases.
How Reactivity Works Under the Hood
Build a TypeScript reactive engine and learn how tracking, computed values, scheduling, cleanup, and batching actually work.
ACID, Isolation Levels, and the Anomalies They Prevent
A practical guide to ACID, concurrency anomalies, MVCC, locks, serializable retries, invariant tests, and database guarantee boundaries.
Browser Rendering: From HTML to Pixels
Follow the browser rendering pipeline from DOM and CSSOM construction to responsive, measurable frames, then diagnose and fix costly work.
Event-Driven Architecture Without the Hype
A practical guide to events, delivery guarantees, idempotency, schema evolution, observability, and knowing when not to use them.
Retrieval-Augmented Generation from Scratch
Build a production-minded RAG pipeline with chunking, hybrid retrieval, reranking, citations, evaluation, security, and observability.
Designing a Distributed Rate Limiter
A practical design for atomic token buckets, resilient enforcement, multi-region tradeoffs, observability, and abuse resistance.
