I build email sending and deliverability infrastructure end to end: self-hosted MTA fleets, automated domain warmup, live reputation monitoring, and the Rust and Python tooling to run all of it. Getting email delivered is a systems problem, and I own every layer, from the metal that sends to the signals that say whether it landed. That platform is PostmasterOps.

I mail one provider, Gmail, and mail it well: focused, measurable, deliverability first. This site is my open notebook. It leans toward email and deliverability, but anything I set up, break, or figure out can end up here, mistakes and all. The code behind the write-ups is on GitHub.
