Team Meeting Bingo held 12 players and fell over at 500. The post-mortem: one DynamoDB partition key, about 250 joins a second, and how I fixed it properly.

AWS gave Lambda a way to run your own web server and hold a connection open. I built a joke bingo app to find out what that's actually for.

I'm not a developer and I've never made a game. I gave a coding agent a 392 character goal: port the Doom engine to TypeScript, unattended. It took 3.5 hours. That was the easy bit.

I got tired of juggling YouTube, Moises and Songsterr to practise improvising, so I built my own on AWS. Here's the serverless architecture and what it actually costs.

My agent memory system was eating 50-80k tokens before I'd typed a word. Here's how Obsidian CLI, Haiku subagents, and a file deduplication hook cut that by 80%. Part 4 of the AI Memory series.

Teaching AI agents to review their own session transcripts, catch lost decisions, and consolidate memory overnight. Part 3 of the AI memory series.

CLAUDE.md instructions are advisory. Hooks are contractual. How I made AI agent memory actually work by adding deterministic enforcement to an Obsidian vault.

Why I'm using plain markdown files for AI agent memory instead of vector databases and semantic search. Sometimes the boring solution is the right one.

How a 500-line bash script evolved into an automated WAF assessment engine - and why deterministic tooling beats giving AI the wheel.

How skills transform AI assistants from context-amnesiacs into genuinely useful collaborators - and why the token savings matter more than you'd think.
