FAQ

About hiring vs engaging in Boston

How fast can you start?

+

Most engagements begin within seven days of the first call. There's no recruiter pipeline, no notice period, no relocation timeline.

React Native or native?

+

RN by default — 90% of features are identical and you ship to both stores at once. Native if you have hard requirements (live activities, complex camera, low-level audio).

Is this a full-time replacement?

+

No — we're a senior engineer on a flat-price engagement. For most pre-seed and seed-stage products, that ships more than a salaried hire would in the same window. When you outgrow it, we hand off cleanly to the team you hire.

Who owns the code?

+

You do, from commit one. Repo in your GitHub, infra in your cloud account. When you do hire someone, they onboard onto your code, not ours.
