Logic that
connects the whole product.

We connect business rules, permissions and integrations in one coherent system.

A white rules engine: the order passes through data and permission checks, and the approved result is saved to the database.
Order#1024
Business rules
ValidationData and rules
PermissionsAccess to operations
Approved#1024
Data in the system
  1. Order #1024Request from the user
  2. Business rulesData validation + permissions
  3. Approved writeResult in the database
Example process · request → checks → storage

Rules first,
then code.

A good backend starts with understanding your business processes. First we model business rules, permissions and integrations, then we select the technology and write the code to implement them.

  • We understand processes and requirements

  • We design logic and permissions

  • We select the technologies

  • We build and develop the backend

One process from input to result

Example order flow in a backend system.

  1. 1. The customer places an order

    Order
    #1024

    Request from the application

  2. 2. The system processes it

    • Data validation
    • Permission checks
    • Applying business rules
  3. 3. The data reaches the database

    Order
    approved

    Store in PostgreSQL or MongoDB

Example solution

An API communication excerpt and an example permissions table.

Request / response (JSON)

POST /api/orders
{ "productId": 123, "quantity": 2, "note": "Urgent fulfilment" }

// 201 Created
{
  "orderId": 1024,
  "status": "confirmed"
}

We define roles and access scope for your system.

Simple logic.
Big possibilities.

Use cases

  • Order flow

    From validation to database storage and notifications to other systems.

  • Dashboard with permissions

    Roles, permissions and access to application data and features.

  • Systems integration

    Connections to payments, ERP and the tools used by your team.

Technology decisions

  • Product API

    A clear API tailored to its users: web applications, mobile applications and integrations.

  • Background processes and tasks

    Queues, asynchronous tasks and scheduled processes.

  • Connecting to an existing system

    Integration with the current environment, taking its limitations into account.

Security in the architecture

  • Access control

    Authentication, authorisation and server-side permission checks.

  • Data protection

    Restricted access, encrypted communications and secure storage.

  • Audit and logs

    Recording important operations, diagnostics and responses to problems.

How we deliver a backend

A clear process. A defined scope at every stage.

  1. 1

    Analysis and design

    We gather requirements. We design the architecture and API.

  2. 2

    Implementation

    We write code, integrate systems and configure environments.

  3. 3

    Testing and deployment

    We check rules, errors and permissions before launch.

  4. 4

    Development and support

    We agree on monitoring, maintenance and subsequent stages.

Frequently asked questions.

How do you choose backend technologies for my project?

We start with the product's processes, data, integrations and requirements. We consider the existing system, team skills and maintenance. We do not assume one technology fits every project.

Can you integrate with our existing system?

First we check APIs, data access, limitations and providers' responsibilities. We then define the integration scope, error handling and how to verify the complete flow.

How do you design a system with complex permissions?

We define roles, resources and permitted operations. Checks run on the server, not just in the interface. We also test access denial and revocation of previously granted permissions.
