The local read

Why hiring a mobile app developer in Boston is hard

Boston founders have access to the best deep-tech talent in the country and almost none of it is hireable at seed stage. Biotechs pay above market for ML engineers. Cambridge robotics shops pay close to that for ROS 2 specialists. The local agency option is mostly enterprise consulting with multi-quarter contracts.

We're not enterprise consulting. One senior engineer owns the build, Eastern Time, overlap with your MIT advisors and Boston-based investors. FHIR or HL7 for healthtech. PyTorch and Hugging Face for ML features. Next.js for the SaaS layer. Flat-price quote in 24 hours. Code in your GitHub from commit one.

A senior mobile app developer here is a ~$336K year-one outlay after benefits, payroll tax, and the 60–90 day search. We're a $10,000+ flat engagement that starts inside seven days.

The work, concretely

What we'd own day to day

The same scope you'd hand to a salaried mobile app developer, owned end to end on a flat-price engagement. No coordination overhead, no junior-on-the-bench, no estimation theatre.

  • Cross-platform RN with Expo prebuild for native modules when needed
  • Push notifications, deep links, OTA updates via Expo Updates
  • Store submission (Apple Developer + Play Console) handled end to end
  • Offline-first storage where it matters (TanStack Query persist or RxDB)
  • Crash reporting, analytics, performance instrumentation wired correctly

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.
