Functional programming on the JVM, expressive enough to build a dialect of your own inside it — for better and worse.
Listed inDivide and ConquerData Structures & Algorithmson
Split, solve, combine — and the master theorem for reading off the complexity without guessing.

Ports, adapters, and pushing I/O to the edges so the core is testable without a database.
Listed inSame-Origin Policy and CORSFrontend Engineeringon
What an origin is, why the preflight happens, and the header the backend was always missing.
Listed inBackups and RecoveryDatabaseson
Point-in-time recovery, RPO and RTO, and the backup nobody tested until the outage.

Atomic cross-project changes against independent release cycles, and the tooling each demands.
Listed inHow the Browser WorksFrontend Engineeringon
Parse, DOM and CSSOM, layout, paint, composite — the pipeline every performance problem lives somewhere inside.
Listed inAccessible ComponentsAccessibilityon
Modals, menus, tabs, and comboboxes — the patterns everyone rebuilds and almost everyone gets wrong.
Listed inCQRS and Event SourcingSystem Designon
