Mobile Engineering

When mobile engineering support helps

Your app is in the stores, users depend on it, and the codebase shows it. Releases are nervous. Crash reports spike after OS updates. Dependencies sit several major versions behind because nobody dares touch the Gradle file.

That is normal for successful products. Mobile is unforgiving: permissions, offline behaviour, store policies and device fragmentation all land in one binary. Generic web practices do not always translate.

We help teams who need senior mobile engineers without building a large permanent squad. That includes greenfield React Native products, brownfield upgrades, and rescue work when a contractor left mid-migration.

Our delivery focus

We care about what happens after launch. Authentication flows that fail on slow networks. Push notification tokens that silently stop updating. Payment SDKs that behave differently on iOS and Android. These details decide whether users trust the app.

Architecture comes first: navigation boundaries, state management that survives refactors, and a clear split between UI and domain logic. We prefer boring, testable modules over clever abstractions that only one person understands.

Tooling matters too. CI that produces installable builds on every merge request, basic device smoke tests, and crash reporting wired before marketing campaigns go live. We have seen teams skip that step and pay for it during peak trading periods.

React Native in the real world

Most of our mobile work is React Native, including Expo where it fits. We assess whether bare workflow, prebuild or full EAS adoption matches your native modules and release cadence. There is no universal answer; there is a documented trade-off for your app.

Upgrade projects follow a sequence: stabilise builds, map native dependencies, pick a target version, upgrade JavaScript packages, then tackle Android and iOS project settings. Skipping the stabilisation step is how teams lose a month to mystery linker errors.

We occasionally work alongside native iOS or Android codebases when a product already exists in Swift or Kotlin and React Native is being introduced module by module.

Outcomes teams notice

Release frequency tends to improve because fear drops. Crash-free rates climb once observability is trustworthy. Product owners get honest estimates because the team shares a picture of technical debt instead of hiding it.

We are happy to embed with your developers, lead a workstream, or run an audit that your internal team executes. The right shape depends on capacity and how much knowledge transfer you need.

Quality signals we implement

Automated checks on pull requests: lint, typecheck, unit tests where they exist, and optional Detox or Maestro flows for checkout or login. Crash reporting with breadcrumbs so support tickets link to sessions. Feature flags for risky UI changes instead of big-bang switches.

Accessibility and performance are not polish at the end. Font scaling, screen reader labels, and list virtualization belong in definition of done. We have seen store reviews mention jank long before executives notice dashboard metrics move.

Enterprise clients sometimes need MDM deployment, VPN-aware networking, or strict data residency. We document those constraints in architecture notes so consumer-grade tutorials do not mislead the team.

When a previous agency left mid-sprint, we start with a read-only audit: build instructions, store credentials ownership, and open incidents. Only then do we estimate feature work. Guessing before that step creates false confidence.

Mobile programmes succeed when product, design and engineering share release criteria. We facilitate that conversation early so “done” means shippable, not merely merged.

Starting a conversation

Bring a one-page summary of users, platforms and the decision that hurts today. Links to crash dashboards, architecture sketches or a repo readme save time in the first call. We do not need NDAs for an initial chat, though we sign them when required for deeper audits.

Expect straight answers about fit. If another partner is better suited, we say so. When we proceed, the first deliverable is usually a scoped proposal: outcomes, assumptions, rough timeline and what we need from your team weekly.

Engagements are invoiced in GBP with clear milestones. We work with procurement teams who need purchase orders and with founders who prefer lightweight email agreements. The mechanics are flexible; the engineering standard is not.

Documentation and handover are part of delivery, not an optional extra. Your team should be able to operate the result without us in the loop for daily fixes, unless you choose retained support.

What we need from your side

Access to repositories, CI, crash reporting and someone who knows recent release history. Product input for prioritisation and a single decision maker for scope changes keeps momentum. Security reviews are normal for enterprise clients; we provide statements of work and can work with your IT contacts.

We align with your sprint cadence where possible. Fixed-date marketing launches still happen; tell us early so upgrade work does not collide with immovable deadlines. Honesty about trade-offs protects customers and staff.

Most programmes benefit from a short retrospective after the first milestone. Capture what to repeat and what to fix in tooling. That habit pays back on the next upgrade cycle.
