We build iPhone and Android products around notifications, camera, location, connectivity, accounts, payments and the backend systems that make the application useful.
Notifications, camera, location, payments and account state only work well when the mobile experience and backend share clear contracts. We choose native or cross-platform engineering around the product's device needs and operating model.
A user may be moving, intermittently connected, responding to a notification, taking a photograph or completing a task in a few seconds. Those conditions affect information density, state, error handling and interaction design.
We assess performance, device capabilities, team constraints, release cadence, expected lifetime and the value of shared code before choosing an implementation approach. The right answer depends on the product, not ideology.
Authentication, token lifecycle, multiple devices, permissions, notification tokens and account recovery all affect both mobile security and the user experience.
Image quality, compression, metadata, upload reliability, privacy and synchronisation all matter when captured media becomes business data rather than a decorative attachment.
Products that need to remain useful with unreliable connectivity require clear decisions about local data, queued actions, conflicts and what happens when the network returns.
Mobile should not become a second backend with different rules. Where practical, the app, web experience and administrative tools use the same business services and data contracts.
App Store and Google Play review, staged rollout, crash reporting, device variation and network behaviour all affect delivery. Mobile engineering therefore continues well beyond producing an installable build.
Connectivity changes, apps are suspended, permissions can be denied and users expect work to survive interruption. A mobile product designed like a continuous desktop session will eventually lose state or create confusing recovery behaviour.
We model local state, retries, caching and synchronisation according to the task. The goal is not universal offline support; it is predictable behaviour when the device environment is less reliable than a development workstation.
A notification may begin a business process, request approval, report a failed action or return a user to a time-sensitive task. Treating push only as a marketing channel misses the need for identity, deep-link context and expired-action handling.
Notification content and destinations should respect what the user is allowed to see when they open them. Sensitive information can stay inside the authenticated app instead of appearing on the lock screen.
Mobile devices can capture documents, scan codes, record media, identify location and authenticate with biometrics. Those capabilities are useful precisely because they are sensitive, so permission requests need context and a fallback path.
We request access when the user reaches the feature that needs it, explain why it is needed and handle denial without trapping the user in a broken flow.
Sessions can expire while an app is in the background, tokens can be revoked and a device can change ownership. Session renewal, logout, secure storage and re-authentication therefore depend on the sensitivity of the product.
Biometric authentication can improve convenience but does not replace server-side identity and authorisation. It is treated as a device-level access mechanism within a broader security model.
Unlike a web deployment, an app release can remain installed on user devices for months and may be reviewed by an app store before distribution. Backend changes therefore need to account for older app versions still in use.
API and release sequencing should preserve compatibility where needed, with staged rollout or feature controls when the product justifies them. A forced upgrade should be a deliberate product decision, not the only recovery mechanism.
Mobile failures can depend on device model, operating-system version, network state or user journey. Diagnostic tools help reproduce those conditions, but telemetry should not collect personal information indiscriminately.
We favour crash and performance evidence tied to a specific release and relevant technical context. The purpose is to shorten diagnosis while keeping data collection proportionate to the problem.
Web, iOS and Android can share accounts, business rules and APIs while still using interaction patterns appropriate to each platform. Forcing every device into pixel-level parity can ignore navigation conventions, input methods and accessibility behaviour users already understand.
We separate product capability from presentation so platform-specific experience does not create platform-specific business logic. The same permission, order or account rule remains authoritative even when each platform presents it differently.
Touch targets, dynamic text, screen readers, contrast, motion preferences and platform navigation all affect whether an app remains usable outside the ideal demonstration. These concerns are easier to address when component and navigation choices respect the platform from the outset.
We treat accessibility as part of interface engineering rather than a final visual check, while recognising that some products may require additional specialist testing.
A device can be lost, backed up, shared or inspected outside the application. Tokens, documents and cached business data therefore need different treatment from harmless interface state.
We minimise sensitive local storage, use platform security facilities where appropriate and avoid keeping information on the device simply because it is convenient for the application.
The product still needs consistent rules and data even when the interface moves across devices and contexts.
Persistent user context and progress should survive changes of channel and session where the product depends on them.
Booking has to preserve service expectations before the customer reaches the physical appointment.
Customer actions need to stay connected to the order state staff are actually fulfilling.
You do not need to turn the problem into a technical brief first. Our job is to understand the business reality and define the right technical direction before it becomes code.
