Your whole business in one click.
We build the system your business depends on and keep it running effortlessly, month after month.
billing-cycle.ts
// billing/domain — the domain knows nothing about infrastructure
export class BillingCycle extends AggregateRoot {
private constructor(
readonly id: CycleId,
private lines: LineItem[],
private status: CycleStatus,
) { super() }
// Invariant: a closed cycle takes no new charges.
// It lives in the aggregate — not in a controller, not in a DB trigger.
addCharge(c: Charge): Result<void, DomainError> {
if (this.status === 'closed')
return err(new CycleAlreadyClosed(this.id))
this.lines.push(LineItem.from(c))
this.raise(new ChargeAdded(this.id, c.amount))
return ok()
}
}Software that's running, not pretty slides.
Three systems we built that are still in production today. Fourteen years of engineering behind each one. That's why you can open them instead of taking our word for it.

A founder runs every interview. Not a recruiter.
- 01
Live coding in your stack
90 minutesA paired session on a representative problem from your domain — not a puzzle from a list. We watch debugging instinct and how they behave when the first approach fails.
- 02
Systems design
60 minutesTrade-offs, failure modes, what breaks at 10×. The tell is whether they have carried a system in production or only read about it.
- 03
Communication & ownership
45 minutesWritten English clarity, async habits, and what they do with an ambiguous ticket. Most of the day is text, so this stage fails candidates the first two passed.
- 04
Paid probation
2 weeksReal work, paid by us, before anyone joins your team. If the signal was wrong, we absorb it — that is the point of running the screen ourselves.
