Services · Enterprise mobility · MDM · Field ops

The Mobility practice at SHRAS builds apps that have to clear procurement, security review and a 12-hour shift in the field. Native and cross-platform engineering, MDM and MAM that the security team will sign, and offline-first architectures that earn the trust of users who cannot depend on a signal.

Native vs cross-platform

The honest decision matrix. No religious wars.

We have shipped both, on the same client, in the same year. The choice depends on the platform-fidelity demands, the lifetime of the app and the team that will own it after we hand over.

Path A

Pick native (Swift / Kotlin)

  • Camera, ARKit, sensor fusion or low-level Bluetooth pipelines drive the experience
  • App lifetime is five-plus years and platform fidelity matters more than ship date
  • Accessibility, regional input methods or right-to-left layouts are first-order requirements
  • The team owns the app long-term and can sustain two codebases without thrash

Trade-off: Two codebases. Two release trains. Two sets of platform expertise on payroll. Worth it when the app is the product.

Path B

Pick cross-platform (React Native / Flutter)

  • Time-to-market is the constraint, and feature parity across iOS and Android is non-negotiable
  • The shape of the app is forms, lists, charts and API calls, not GPU or sensor work
  • A single product team owns the roadmap, with native bridges only where the OS demands them
  • You expect to fold in a web companion and want to share types, validation and design tokens

Trade-off: Native bridges still exist. Upgrade cycles are real. Performance cliffs near complex animations need design pushback, not engineering heroics.

The MDM & MAM stack

Five layers your CISO will recognise.

Mobility security is not a single tool. It is a stack, from device hardware up through identity. We engineer each layer with the vendors already in your tenancy, and we test the seams.

Layer 05

OS & hardware

iOS, iPadOS, Android Enterprise and Wear OS targets. Minimum-OS contracts, device classes and the supplied-vs-BYOD split written into the engagement.

  • iOS 16+
  • Android 12+
  • Zebra TC-series
  • Apple Business Manager

Layer 04

Device policy (MDM)

Enrolment, configuration, posture and remote wipe. Enforced over Apple DEP / Android Zero-Touch with conditional access tied to Entra ID or Okta.

  • Microsoft Intune
  • VMware Workspace ONE
  • Jamf
  • Hexnode

Layer 03

App management (MAM)

Per-app policies for copy-paste, save-as and Open-In. Managed app config delivers tenant URLs, certificates and feature flags without rebuilds.

  • App-protection policies
  • Managed AppConfig
  • Container apps
  • Per-app VPN

Layer 02

Identity & access

OIDC and SAML brokered through corporate IdP. Conditional access binds the device posture to the session, biometric step-up at sensitive boundaries.

  • Microsoft Entra ID
  • Okta
  • Auth0
  • FIDO2 / Passkeys

Layer 01

Backend & data

Mobile-aware APIs sized for unreliable links. Token rotation, request signing, payload minimisation, and audit trails on every privileged call.

  • Node / .NET / Java APIs
  • GraphQL gateways
  • API Gateway + WAF
  • OpenTelemetry

Offline-first architecture

The signal is optional. The work is not.

Field operations is where most enterprise apps fail. Our default architecture assumes the network will be unreliable, the device will be killed mid-shift, and two technicians will edit the same record at the same time.

  1. 01

    Local-first cache

    Every screen reads from a local SQLite or Realm store first. The network is an enhancement, not a dependency.

  2. 02

    Operation queue

    Writes go to a durable queue with optimistic UI and a stable client-generated id. Survives kills, crashes and 12-hour shifts.

  3. 03

    Background sync

    Workers drain the queue when connectivity returns, with exponential backoff, partial-batch resume and bandwidth-aware payloads.

  4. 04

    Conflict resolution

    Last-writer-wins is rarely what the business wants. We model conflict explicitly: per-field merge, server-authoritative fields and human-in-the-loop where needed.

  5. 05

    Audit & replay

    Every sync is logged with a tamper-evident trail so auditors, ops and engineering can replay what happened at 3am in the field.

Enterprise integration

Mobile apps live or die on the integration plumbing behind them.

A great app is a thin glass over a system of record. We build the glass and the gateway both, with the same team that runs our SAP, Oracle, Dynamics and Salesforce practices.

  • ERP
    • SAP S/4HANA
    • SAP NetWeaver Gateway
    • Oracle E-Business Suite
    • Microsoft Dynamics 365

    OData, BAPI, REST and SOAP wrappers; offline-tolerant write-back patterns.

  • CRM
    • Salesforce
    • Microsoft Dynamics CE
    • SugarCRM
    • SuiteCRM

    Mobile SDKs where they help; thin REST and GraphQL gateways where they do not.

  • Service & assets
    • EnFieldo
    • IBM Maximo Real Estate & Facilities
    • Archibus
    • ServiceNow
    • ManageEngine

    Field-tech apps wired into work-orders, permits, isolations and asset history.

  • Identity & collab
    • Microsoft Entra ID
    • Okta
    • Auth0
    • Microsoft 365 Graph

    Single sign-on, conditional access, calendar and document deep-links.

  • Custom
    • REST
    • GraphQL
    • gRPC
    • MQTT / WebSocket

    Where systems-of-record sit behind a custom estate, we build the gateway too.

Field-ops case patterns

Three shapes we keep delivering, in the kinds of environments that don’t forgive shortcuts.

  • Oil & Gas

    Oilfield permits-to-work

    Problem
    Permits, isolations and JSAs were paper, double-keyed at shift end, with multi-day delays before HSE could see a violation pattern.
    Build
    Hardened Android tablets on a Zebra fleet, Intune-managed, with an offline permit workflow wired into Maximo. Photos, signatures and gas-test readings captured in the field, queued, and reconciled on reconnect.
    Outcome shape
    Permit cycle-time compressed from hours to minutes. HSE dashboards trend in near-real-time. Outcome shape: meaningful reduction in lost-time incidents and audit-finding repeats.
  • Healthcare

    Hospital nurse rounds

    Problem
    Vitals, intake-output and pain scores were captured on paper, transcribed at the nurses station, and frequently lost between shifts.
    Build
    iOS bedside app under Workspace ONE, biometric-guarded, with HL7 / FHIR sync into our HIS. Offline rounding, barcode patient-ID, structured notes that respect CBAHI and JCIA documentation rules.
    Outcome shape
    Charting time per round dropped sharply. Documentation completeness improved against accreditation rubrics. Outcome shape: better ratios of patient-time to chart-time, fewer transcription incidents.
  • Retail

    Retail store ops

    Problem
    Store managers juggled three apps for stock counts, planogram audits and shrink reporting, with no view of compliance across the chain.
    Build
    React Native app on a managed Android fleet, single sign-on through Entra ID, offline-tolerant tasking, photo evidence and signature capture, integrated with the WMS and a Power BI dashboard for ops leadership.
    Outcome shape
    Tasking compliance visible per-store, per-day. Manager admin time fell. Outcome shape: faster shrink response, cleaner stock accuracy, less app-switching on the shop floor.

Security defaults

What every SHRAS mobile build ships with, before anyone asks.

These are not options. They are the baseline. Anything tighter, regulated banking, MoH-grade health, or government accreditation, layers on top.

Certificate pinning

Pinned roots and intermediates with a documented rotation runbook, not a one-time hardcode that breaks at the worst moment.

Biometric & step-up

Face ID, Touch ID and Android BiometricPrompt for session unlock and sensitive actions, with PIN fallback and replay protection.

Secrets management

No long-lived secrets in the binary. Tokens minted server-side, rotated, scoped and bound to device posture.

MASVS-aligned testing

OWASP MASVS-L2 controls baked into the test plan: storage, crypto, network, platform interaction and code-quality categories.

Regular pen tests

Annual third-party penetration tests on flagship apps and a continuous in-house program for the rest, with remediation SLAs.

Frequently asked

The questions that come up before every mobility engagement.

  • When should we choose cross-platform over native?

    Cross-platform earns its keep when feature-parity across iOS and Android is non-negotiable, when the app is mostly forms, lists and charts, and when one product team owns the roadmap. Pick native when the experience leans on platform-specific sensors, when accessibility and localisation are first-order, or when the app is the product and lifetime exceeds five years.

  • React Native or Flutter?

    Both ship production-grade apps. We default to React Native when the client already has React on the web and wants to share types, validation and design tokens. We default to Flutter when the design language calls for tightly-controlled rendering, or when the team wants a single language end-to-end. Either way, we plan for native bridges from day one.

  • Do you have a preferred MDM vendor?

    We are vendor-neutral. In practice, Microsoft Intune wins where the rest of the estate is on Microsoft 365 and Entra ID. Workspace ONE wins for mixed fleets and rugged Android. Jamf wins for Apple-heavy environments. We will integrate against whichever is already in your tenancy, and we will tell you when the choice is going to hurt.

  • How do we distribute enterprise apps without going through the public stores?

    Three patterns: Apple Business Manager with custom app distribution to known organisations, Android Enterprise private apps via Google Play, or fully self-hosted MDM-pushed binaries. We map the right mix to your audience, audit posture and update cadence, and we own the signing, provisioning and release pipeline.

  • How is offline data kept private and compliant?

    Encrypted at rest with iOS Data Protection or Android EncryptedSharedPreferences. Sensitive payloads scoped to the smallest practical retention window. Wipe-on-unenrol, wipe-on-jailbreak and wipe-on-policy-violation, with audit trails tied to the user, device and tenant. Compliance posture mapped to GDPR, PDPL, HIPAA or sector-specific rules at design time, not after a finding.
