Documentation Portfolio

I write things down as I work: what I changed, why, how to undo it, and what someone else needs to run it without me. The documents below come from my own infrastructure and client work. They’re redacted for security, and the IAM templates use fictional data in place of any employer’s records.

Hiring teams can review the full set. Request access, and once I approve you, you’ll sign in with a one-time code sent to your email. Access lasts 14 days.
