I joined DAERO in September 2025 as its first engineering hire, shortly after the pre-seed. DAERO is backed by and . I’ve worked on two complete redesigns of the app. The product still ships and the team carries on without me, so what follows is only the part I can account for.
What I owned
The client observability stack, end to end. The analytics contract lives in a separate repository that generates typed Swift. I wrote the consumer side: 88% of the iOS Observability package, covering the event client, the session model, and the dashboards behind it.
The design system, 68% of that package. Three interface redesigns went through it.
The feature layer, about half.
On the numbers
On the rewrite, I made 1,963 of the 2,375 non-merge commits, which is 82.7%. My share of its surviving lines is 34.1%. Both are true. The gap comes from how I work: I commit in small pieces, and a lot of what I wrote early was later replaced. I mention both because the commit figure on its own reads as a claim about code volume, and git blame would refute it in about a minute.
On the first version, which predates me, I made 91 of 342 commits.
The string catalogue at my departure carried 748 keys across English, Spanish and Portuguese. Russian and Ukrainian were added after I left.
I don’t have user or project counts to give. The dashboards I built define the panels that would show them, and I no longer have access to the data behind them.
