Build a company's entire delivery platform from the first commit, own it outright, and never carry a pager. Both halves of that sentence are deliberate.

In Your First Few Months You Will
Build the platform from code. Hosts, networking, ingress, access, environments — committed, parameterised, reviewable. It is the cheapest moment this will ever be done, and you get to do it properly instead of retrofitting it. Make deployment self-serve. Today, shipping an existing app is a git push; standing up a new one needs admin rights and two undocumented footguns.

Commit to production, an automated test gate, per-branch preview URLs a stakeholder can open from their phone, and a rollback that everyone on the team has rehearsed before they need it. Then keep it all running — and keep making it duller. Observability, cost caps, dependency hygiene, the unglamorous work that decides whether a small team can own a lot of products.
