OUR APPROACH

From first conversation to delivered results.

01 / 04

Understand the product

Map customer workflows, existing code, devices, data and release goals.

02 / 04

Design the app and API contracts

Define client state, sessions, navigation, backend responsibilities and failure recovery.

03 / 04

Build and test

Implement features with device-level, accessibility, network and negative-path coverage.

04 / 04

Release and improve

Prepare signing, staged rollout, crash monitoring, handoff and follow-up improvements.

TECHNICAL EXAMPLE / SYSTEM BOUNDARIES

Mobile sessions across interruptions and recovery

Native mobile code owns navigation and local state. The backend owns permissions. The integration must behave safely when requests time out, sessions expire or the user changes accounts.

TECHNICAL WALKTHROUGH

Mobile security: the device is not the authority

An original visual walkthrough of authentication signals, sensitive data, and server-owned authorization decisions.

Read the walkthrough transcript
  1. A native mobile client can store a session and collect an integrity signal, but those signals cannot grant unlimited access.
  2. The backend authenticates the user and checks the resource and requested operation for every protected API call.
  3. A malicious client can replay or modify a request. Protected operations must be enforced on the server.
  4. Validate revoked sessions, retries, offline sync and user switching before release.

Frequently asked questions

Can you take over an existing iOS or Android app?

Yes. We can investigate inherited code, stabilize build and lifecycle issues, or deliver an incremental modernization plan.

Do you cover backend APIs as well?

Yes. Client/server authentication, authorization, API integration and failure recovery are part of our engineering practice.
