Engineer at heart, found working on products, projects, microservices & APIs in Node.js, familiar with databases, templating, testing & devops.

Reference documents on things I've learned, use regularly, or keep having to look up. Focused on CLI tooling, Git, AWS, and TypeScript/Node - but anything goes.

If something tripped me up, cost me an afternoon, or turned out to be simpler than I expected, it probably ended up here.

What's in here

Most documents follow the same pattern: quick examples first, explanation second. This is a cheat sheet, not a tutorial - if you need deep background, the upstream references are usually linked at the top of each document.

Topics lean towards:

• CLI & Terminal — one-liners, shell tricks, tools I reach for daily
• Git & version control — workflows, commands, conventions, etc
• AWS & cloud infrastructure — services, patterns, tradeoffs I've worked through
• TypeScript & Node — syntax references, gotchas, setup decisions

Why a public wiki

Partly so I can find things again. Partly because if I had to figure it out, someone else probably does too.

Everything here reflects how I actually work - opinionated in places, incomplete in others. If something's wrong or out of date, please open an issue.

The information in this repository is public-knowledge or AI-generated, there are no private knowledge or company-specific details.

Archived

Some items are archived - typically because I've not needed them in a very long time.
