Mobile performance · Releases · Full builds

Mobile apps that work properly at scale.

Most apps get built, shipped, and then quietly degrade. I build new apps too, but the work I'm unusually good at is the part after launch.

01 · The problem

Shipped is not the same as healthy.

I've spent years on exactly this inside a travel app with millions of users: startup performance, platform upgrades that don't break things, and a release process that runs without drama.

  • Launch time creeps up.
  • The release process becomes a weekly ordeal.
  • The app gets slow on the devices most of your users actually own.

02 · What I help with

From first build to every release after.

03 · Two ways to work together

Advice or hands. Every service comes either way.

$ consult

I tell you what to do.

I look at your app or process and give you a clear plan.

For an existing app, that's a Diagnose: a short engagement on why it's slow, why releases hurt, and what would fix it. It ends with a written answer you could hand to your own team.

$ implement

I do the work.

Delivered to an agreed scope.

A complete mobile solution from app to backend, a faster app, or the automation your team is still doing by hand.
