Model the product
Terms, roles, data and states need a consistent meaning. A clear model connects the interface, services and existing systems.
DEEPBURG / MULTI-PLATFORM APP DEVELOPMENTOne product.
One product.
Four contexts.
We develop apps that work together across devices. Business rules and data form their shared foundation. Views, input methods and device capabilities follow how people actually use the product.

ONE SYSTEM / DISTINCT EXPERIENCESCOREWEBiOSANDROIDDESKTOP
THE ARCHITECTURE QUESTION
What should be shared, and what deserves its own design?
Shared components help keep changes coherent across platforms. Distinct implementations make sense where interaction, device capabilities or operation require them. Requirements, the team and maintenance needs determine the boundary.
Design for the platform
Documenting work on a phone calls for different input from reviewing it at a desk. Navigation, offline behavior and system integration follow that context.
Record the decision
We compare technical approaches against requirements and dependencies. Shared components, separate implementations and the reasons for each choice are documented.
FOUR USAGE CONTEXTS
Interaction starts with context.
Web
Overview, collaboration and directly accessible workspaces. Keyboard interaction, different screen sizes and supported browsers belong in the design.
iOS
Focused tasks on the move. Navigation, touch input and useful capabilities such as the camera form one understandable flow.
Android
Mobile use on the agreed devices and system versions. Layout, navigation and behavior with changing connectivity are planned for that selection.
Desktop
Comparing, editing and spending longer with the product. Keyboard input, windows, file exchange and appropriate information density support those tasks.
ILLUSTRATIVE DECISION RECORD
Shared rules. Distinct implementations.
An app needs sign-in, offline work and several release paths. This example shows possible boundaries between shared planning and platform-specific implementation.
| TOPIC | SHARED | PLATFORM-SPECIFIC |
|---|---|---|
| Identity | Roles, access rules and authorization by connected services | Sign-in flow, device storage and local authentication |
| Offline | Data meaning, pending changes and conflict rules | Local storage and permitted background execution |
| Release | Quality goals, supported versions and acceptance criteria | Web publication, store review and desktop distribution |
A concept study with hypothetical requirements. Actual system boundaries are determined for the project.
ENGINEERING DECISIONS IN EVERYDAY USE
Built for everyday conditions.
People still need the product when a connection drops, several colleagues edit the same data or a connected system changes. Those situations belong in the design. The project agreement defines their implementation.
When the connection drops
Reading, saving locally and transferring changes are distinct tasks. We establish which must work offline, how pending changes stay visible and who resolves conflicts after synchronization.
When people work together
A role model defines who can read or change which data. The interface shows permitted actions; connected services check authorization for each request. Collaborative editing also needs rules for outdated data.
When existing systems are connected
Data contracts describe meaning, format and permitted changes. Reliable integration also needs defined error handling, version transitions and ownership. Migration and service outages belong in the plan.
When a release is due
The web, app stores and desktop distribution have distinct release paths. We define supported versions, signing and store accounts, acceptance criteria and the response to faulty releases. The timing and outcome of external store reviews remain outside our control.
FROM IDEA TO RELEASE
Critical decisions happen early.
We define key tasks, users and platforms. The result is a prioritized first scope with explicit open questions.
Data flows, interfaces and security boundaries are established. Critical technical assumptions get a focused investigation.
Reviewable versions show progress and outstanding work. Agreed use cases and failure scenarios provide the basis for acceptance.
Release paths, source code, accounts and operational responsibilities have clear owners. Further development and maintenance are prepared within the agreed scope.
What a useful proposal makes clear.
It names target platforms and supported versions, functional scope, acceptance criteria, release path, source and account ownership, maintenance and updates. The actual deliverables are agreed individually.
Choosing an implementation
Multi-platform or native?
Shared code is one architectural option. The choice depends on what the product must do, how it uses each device and who will maintain it.
What we compare
- Required device functions and supported versions
- Offline behaviour, responsiveness and data volume
- Accessibility and platform conventions
- Release processes, team experience and long-term maintenance
The outcome can be a mixed architecture: shared product rules and services, with native components where the task benefits. We record the boundaries before implementation.
