Matt Pocock

Teacher (formerly the TypeScript educator โ€” "you see why I stopped teaching TypeScript, cuz AI knows everything now"), now teaching AI-assisted development via AI Hero and conference workshops. His AI Engineer Europe workshop (Apr 2026, 1.6M views) lays out the archive's most complete end-to-end workflow: grilling-session โ†’ unread PRD โ†’ Kanban DAG of tracer-bullet-slices issues โ†’ Docker-sandboxed Ralph loops with TDD โ†’ human QA. Built Sandcastle, a TypeScript library for parallel AFK agent loops (planner โ†’ sandboxed worktree implementers on Sonnet โ†’ Opus reviewer with pushed standards โ†’ merger agent).

Signature positions: fundamentals-first ("20-year-old books... an absolute gold mine to throw into prompts" โ€” Brooks, Ousterhout, Pragmatic Programmer); specs-to-code is "vibe coding by another name" (vibe-coding) โ€” "the code is your battleground"; own your planning stack rather than adopt frameworks (Spec Kit etc.); feedback-loop-ceiling; clear-don't-compact; QA as taste enforcement against slop-content. Uses Claude Code while cheerfully disliking it ("democracy is the worst way to run a country apart from all the other ways"). Works on Windows, on purpose.

Same agentic-engineering territory as dhh but with opposite temperament: DHH under-specifies and iterates; Pocock front-loads alignment, then leaves the loop.
