They asked if you have a tech team.

I'm Jeremy Callahan. I do the build myself. You can tell them yes: the website or the app, from the Figma your team approved, under your agency's name. $8,200 a month. Pause it when the project ends.

See the work

The question after the design

They like the work. Then they ask who is going to build it.

That question is the account. If the answer is no, or "we'll find someone," they start looking for a team that can build what you designed. The next round of design often goes with them. If the answer is a quick yes, the build goes to whoever can start.

  • Handed to someone else. The yes gets passed to a junior, or to an offshore team. You see what they did to the file in the review.
  • Thinner than the file. Type, spacing, and motion come back simplified. Your team can see it. So will the client.
  • Fine until the next ask. Accounts, payments, the parts the prototype skipped. The demo never included them, and the person who built the demo often can't.
  • Your people, in the tickets. Whoever sold the work spends the week answering for code they didn't write.

You stay in the room and answer yes. I write the code in your repo.

How a month runs

The terms, before anyone gets on a call

Fee
$8,200. Pause or stop when the project ends. A long week doesn't change it.
Who
I write the code. Senior work, and it stays with me. A junior doesn't take the ticket. An offshore team doesn't take the nights.
Pace
One project during the month. I put work up for you to review two or three times a week, so you see it before a pile of changes lands at the end.
Access
Your Slack, your GitHub, your Linear. You write to me. There is no account manager on my side.
Client
I work under your name, including an email on your domain, or I stay off the client entirely. You choose before we start.
Handoff
You get the repo, notes a new engineer can actually read, and the IP.
Changes
New work replaces something already in this month, or it waits. A separate build is a separate month. This month stays $8,200.

What I build

The jobs that stall after the design is approved

Web and apps

Website, iOS, or Android

  • Web
  • iOS in Swift and SwiftUI
  • Android in Kotlin
  • React Native when one codebase is the point, and the design still holds

The file you designed

If a screen can't be built as drawn, I say so first

  • Type, spacing, and components from the Figma file
  • Motion that's specced in the file
  • Empty, error, and loading states called out before I invent them

Prototypes and MVPs

When they need to see it work before they commit

  • A prototype that behaves like the product, not another clickable file
  • An MVP limited to the path the client has to try
  • The same build continues if they say yes to the rest

The backend

Accounts and data

  • Node and Python
  • Firebase or Supabase
  • AWS when the job calls for it

The fee

One number your producer can put in the estimate

Per month

$8,200 / month

The client never gets a bill from me.

Work a client would notice

A product, a design, a date, and someone who will see if it's wrong
