Engineering as a Service

A senior full-stack engineer by the month. You bring the work; your hours are reserved, every change is reviewable, and the code lives in your own repository.

Taking new clients · two engagements at a time

Who it's for

Startups without engineers

You have an MVP to build or rescue, or a live product nobody is keeping moving. You need someone who can build it and make the technical calls.

Organizations without a dev team

You have a backlog of website, integration and internal-tool work, and no one to give it to. Hiring for it would take months.

Agencies and IT firms

Your clients need development and you don't have developers. Reserve hours and put them to work on your clients' projects.

Plans and prices

You pay for reserved time, not a guess at scope. Every plan is priced at $125 an hour, and every engagement starts with a scoping session.

Scoping session

Four hours to understand the ask and recommend a plan.

$500

Every engagement starts here

  • A call about your goals, users and constraints
  • A read through your code, or your idea if there's no code yet
  • A written plan and the tier it needs
  • Credited to your first invoice

The terms, in plain words

  • Paid monthly in advance. Change or cancel with 30 days' notice after the minimum term.
  • Unused hours don't roll over. Extra hours only with your written OK, at the hourly rate.
  • All work lives in your own repository, and you own the code.
  • Every change is a pull request you can review on a preview link before it ships.
  • A written update every week: what was done, what's next, hours used.
  • A reply within one business day.

How it works

  1. Tell me what you need

    A short call about the work, the people it's for and what's already built.

  2. Scoping session

    Four hours with your code or idea, then a written plan and the tier it needs.

  3. Reserved time

    Your hours are booked each month. You add to the backlog; I work through it in your order.

  4. Reviewable changes

    Each change is a pull request with tests, checked on a preview link before it ships.

  5. Weekly update

    Every week, in writing: what shipped, what's next and the hours used.

Questions

Why not just hire an engineer?

A senior hire costs more than half-time here, takes months to find and is hard to undo. Start part-time, and if you outgrow it I'll help you hire and hand over cleanly.

What if you're busy with another client?

Your hours are reserved, and I take two engagements at a time so that's real. The weekly update shows where the hours went.

What happens to the code if we stop?

Nothing changes hands, because it was always yours. The code, tests and documentation live in your repository from day one, so any engineer can pick it up.

Can we get a fixed price instead?

Yes, for a well-defined project: that's a proposal with a fixed scope. When the work is ongoing or still taking shape, paying for time costs less than paying for the padding in a fixed quote.

Do you work with agencies?

Yes. Agencies and IT firms without developers can reserve hours for their own clients' work.

Start with a scoping session

Four hours, $500, credited to your first invoice. You'll leave with a written plan whether or not we work together.
