API backend + mobile application

We build complete digital systems combining an iOS and Android mobile application, secure API backend, database and administration panel.

  • Mobile application and backend from one team
  • Unified architecture and business logic
  • A secure foundation for future development

Who the complete solution is for

Startups with a new product idea

For developing a working MVP that includes the mobile application, server-side logic, users and administration tools.

Businesses without an existing backend

When the application must be developed from the ground up together with its database, API and required integrations.

Companies with internal workflows

For mobile management of tasks, requests, schedules, documents, employees, inventory or service operations.

Online services and platforms

For bookings, deliveries, orders, payments, subscriptions, customer profiles and notifications.

Field and service teams

For applications that send locations, photographs, signatures, reports and completed work orders to a central system.

Existing web systems

For adding a mobile application and API layer to a CRM, ERP, SaaS platform, online store or internal system.

Products with multiple interfaces

When one backend system must serve a mobile application, web interface, administration panel and external partners.

How we develop the API and mobile application

Consultation and product concept

We clarify the problem, target users, core functionality, business model and desired result.

MVP planning

We define the minimum feature set for the first working version and prioritise the remaining functionality.

Technical architecture

We design the mobile application, API resources, database, user roles, integrations and infrastructure.

UX and prototype

We prepare the structure, navigation and an interactive prototype of the main user scenarios.

UI design

We create the visual interface in accordance with the brand and mobile conventions for iOS and Android.

Backend and API development

We develop the database, authentication, business logic, administration panel and secure API endpoints.

Mobile application development

We implement the screens, API communication and required mobile device functionality.

Integrations and automation

We connect payments, couriers, CRM, ERP, notifications, storage services and other external systems.

Complete system testing

We test the application, API, permissions, data and integrations through real end-to-end scenarios.

Deployment and publication

We deploy the backend, prepare the mobile builds and assist with submission to the application stores.

Monitoring and support

After launch, we monitor errors, workload and critical processes and develop future versions.

Technology and architectural approach

  • React Native and TypeScript for iOS and Android
  • Laravel and PHP for API backend and business logic
  • REST APIs using JSON requests and responses
  • MySQL or PostgreSQL for data management
  • Laravel Sanctum, Passport or a suitable OAuth mechanism
  • Role-based access control and detailed policies
  • Administration panel for system management
  • Redis for caching and temporary data
  • Queues and background jobs for demanding operations
  • Push notifications through platform services
  • Webhooks for external system communication
  • Object storage for images, files and documents
  • Secure storage for tokens and sensitive information
  • Maps, GPS, camera and other device capabilities
  • Rate limiting and protection against excessive requests
  • Database transactions for critical operations
  • OpenAPI documentation for API resources
  • Feature, integration and mobile testing
  • Docker, Git and separate development and production environments
  • Centralised logging and error monitoring
  • Backups and a documented data recovery plan

What determines the complete solution price

The price is set individually after consultation. It typically depends on:

  • Number of screens and user scenarios
  • Number of API resources and backend modules
  • Complexity of the business logic
  • Number of user roles and access levels
  • Company accounts, teams or organisation requirements
  • Complexity of the administration panel
  • Online payments, subscriptions and purchases
  • Push notifications and automated communication
  • Camera, GPS, files and other device capabilities
  • Offline mode and data synchronisation
  • Number and complexity of external integrations
  • Large file processing and storage requirements
  • Data volume and migration requirements

  • Infrastructure and production configuration
  • Publication and ongoing technical support

Frequently asked questions

What does the API + mobile application service include?

It includes development of the mobile application, server-side business logic, database, secure API and, when required, an administration panel and external integrations.

Why does a mobile application need an API backend?

The backend stores shared data and manages users, permissions, payments and business rules. The application communicates with it through secure API requests.

Can a mobile application work without a backend?

Only very limited applications using entirely local data can operate without one. User accounts, shared content, payments, orders, notifications and administration generally require a backend.

Can one API serve both a mobile and web application?

Yes. A properly designed API backend can serve a mobile app, web interface, administration panel and external integrations.

Will the system include an administration panel?

Yes, when users, content, requests, orders, payments, settings or other business data need to be managed.

Can the application connect to an existing system?

Yes, when that system provides an API or supports the development of a suitable data exchange interface. We perform a technical assessment before development.

Can we begin with an MVP?

Yes. We generally begin with the core user scenarios and required backend functionality, then introduce additional modules based on feedback.

How is the API secured?

We use encrypted connections, token or OAuth authentication, permission checks, validation, rate limiting and logs of critical actions.

Can the application work offline?

Certain functions can use locally stored data and synchronise later. This requires predefined rules for resolving conflicts and refreshing data.

Can the application send push notifications?

Yes. The backend can send automatic notifications when a new event, status change, message, deadline or marketing campaign occurs.

Can the product include payments and subscriptions?

Yes. We can integrate a suitable payment provider and manage plans, payments, renewals and access according to the product rules.

Can a web application be added later?

Yes. When the API and backend are designed correctly, a web interface can be added without rebuilding the complete business logic.

Who owns the developed source code?

After project completion and payment, you receive the agreed rights and access to the mobile application, backend system and developed source code.

How long does development take?

The timeline depends on the mobile application, backend modules, administration panel and integrations. A smaller MVP generally takes several months, while a complex product is delivered in phases.

Do you provide support for both the application and backend?

Yes. Support can include monitoring, backups, updates, issue resolution, optimisation and development of additional functionality.
