Published April 10, 2026. Documents how I ship cross-platform apps for organizations that need one codebase with a real deployment process.

London mobile app work is usually internal tooling rather than consumer apps — scheduling, inspection, patient-facing content apps. Expo Managed workflow handles almost all of it, and EAS Update lets small teams ship fixes without a review cycle.
London, Ontario's tech community is small but active, anchored by Western University and a growing base of healthtech, agtech, and software companies. Projects here tend to have long-term horizons — founders building locally want partners they can work with over years, not sprints.

Expo-based architecture with EAS Build and Update for fast iteration
Navigation, state management, and offline-first data layer
Native module integration where the JS side cannot reach (audio, background, BLE)
Authentication, push notifications, analytics, and crash reporting
Store submission: App Store Connect, Google Play Console, review prep
Post-launch OTA update flow so fixes reach users without a new binary
How engagements run
- 01
Scoping and architecture
Pin the core user flows, offline requirements, and integration points before any build. Pick the right Expo config (managed vs. bare) for the actual needs.
- 02
MVP build
Ship the core flows on TestFlight and Play internal testing fast. Early feedback drives scope decisions before money goes into polish.
- 03
Native integration
Add native modules, background tasks, streaming, or device APIs where required. Keep the codebase managed wherever possible.
- 04
Store submission
Assets, privacy disclosures, review notes, and response loops with App Store and Play reviewers until both builds are live.
- 05
OTA and iteration
EAS Update pipelines so bugfixes and content changes reach users in hours, not days. Analytics review loops to guide next iteration.
FAQs — Mobile App Development in London
Do you work with London-based businesses?
Yes. I take on mobile app development engagements with clients in London and across the Southwestern Ontario. Most work runs remote-first with in-person touchpoints where useful, and I'm used to the Ontario business environment.
What London teams usually hire you for mobile app development?
London work in this service area usually comes from healthtech, agtech, insurance teams that need a senior partner to scope the work clearly and ship it without adding process overhead.
Do you only cover London, or the wider Southwestern Ontario?
The work is scoped around London, but delivery usually extends across the wider Southwestern Ontario, including Kitchener-Waterloo, Hamilton and remote-first teams that need the same service.
Expo or bare React Native?
Expo managed workflow for almost every project — it is faster, has better tooling, and now supports custom native modules through config plugins. Bare workflow only when a hard native requirement forces it.
Can you take over an existing React Native app?
Yes. I regularly take over apps with technical debt, outdated dependencies, broken upgrade paths, or failing store submissions. The first step is always a short audit and a prioritised fix plan.
