The local read
Why hiring a mobile app developer in London is hard
London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.
Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.
A senior mobile app developer here is a ~$232K 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.

Why this beats a hire
One AI-native engineer.
The output of a team.
One senior mobile app developer plus AI agents now ships what four engineers used to. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.

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
Stack we use
Defaults — we deviate when the project demands it, not because something is fashionable.
