Our expertise

Server-side programming for robust web and mobile applicationsdata management and API creation.

THE backend development is the invisible but essential engine of any dynamic web or mobile application. It manages the business logic, data processing, communication with databases, security and the creation of APIs that feed the user interfaces (frontend). Geekworkers, a tailor-made development in Lausanne, has a team of experienced backend developers capable of building robust, high-performance and secure server systems using leading languages and frameworks such as PHP (Laravel, Symfony), Node.js and Python (Django, Flask).

Business Logic and Data Processing

We code the application logic specific to your projectThis ensures that data is processed correctly, inputs are validated and business rules are executed.

Creation of RESTful and GraphQL APIs

Development ofHigh-performance, secure APIs (RESTful or GraphQL) to enable your front-end applications (web or mobile) or third-party services to communicate with your back-end.

Integration with databases

Effective connection and interaction with different types of databases (SQL such as MySQL/PostgreSQL, NoSQL such as MongoDB) to store and retrieve information. See our expertise in Database Management.

Backend Security and Performance

We apply the good practice in secure development (OWASP), optimising requests and server logic for fast response times and high reliability.

FAQs

The backend is the "engine room" of your application. Without a solid backend, your application cannot function properly, store data securely or offer dynamic functionality. It is the the technical core that ensures reliability, performance and scalability of your digital solution. Our full stack developers in Lausanne are experts in this field.

The choice depends on a number of factors: the nature of the project, the performance requirements, the existing ecosystem and the skills of the team. PHP with Laravel or Symfony is very robust, mature and excellent for complex web applications and APIs. Node.js is very efficient for real-time applications, microservices and APIs thanks to its non-blocking model. We recommend the best option.

An API (Application Programming Interface) enables different applications to communicate with each other. Developing an API for your backend is essential if you have a a separate front-end application (e.g. a React SPA or mobile app), or if you want third-party services to be able to interact with your data or functionalities in a controlled manner. See ourAPI integration.

We implement several layers of security: strict validation of input data, protection against injections (SQL, XSS), secure authentication and session management (JWT tokens, OAuth), encryption of sensitive data, regular dependency updatesand we follow the OWASP recommendations.

YesIf you have an existing backend that requires maintenance, performance optimisation, security fixes or the addition of new functionalities, our backend developers in Lausanne can analyse your code (PHP, Node.js, etc.) and propose an intervention plan. Contact us for a backend development quote.
