Our expertise

Design and programming of server logic and APIs for your high-performance web and mobile applications.

THE backend development is the backbone of any complex digital application. It is the "submerged part of the iceberg" that manages business logic, data processing and storage, security, and communication with user interfaces (frontend) via APIs. Geekworkers, a tailor-made development in Lausanne, has a team of experienced backend developers, capable of building robust, high-performance, secure and scalable server systems for your web and mobile projects in Switzerland. We use cutting-edge languages and frameworks such as PHP (with Laravel or Symfony), Node.js, or Python (with Django or Flask).

Scalable Backend Architecture

We design backend architectures (monolithic, microservices) adapted to your current and future needs, prioritizing performance, maintainability and scalability.

Development of high-performance APIs (REST, GraphQL)

Creation ofWell-structured, documented and secure APIs to enable your frontend applications or third-party services to interact efficiently with your business logic and data.

Optimized Database Management

Effective interaction with various types of databases (MySQL, PostgreSQL, MongoDB, Firebase), including schema design, query optimization, and data integrity management. See our expertise in Database Management.

Security Built-in by Design

We apply the secure development best practices (OWASP Top 10) at every step: input validation, protection against common attacks, authentication and authorization management. This service is a component of Web & Mobile Development.

FAQs

A solid backend ensures that your application is reliable (it works as expected), efficient (it responds quickly), secure (your data and that of your users is protected), and scalable (it can support an increase in the number of users or data)This is the driving force behind your digital solution. Our experts in Lausanne attach vital importance to it.

We have strong expertise in PHP with Laravel and Symfony frameworks, which are excellent for complex web applications and robust APIs. We also use Node.js (with Express.js or NestJS) for its real-time performance and JavaScript ecosystem. Python (with Django/Flask) is also an option for some projects.

An architecture microservices consists of dividing a complex application into several small independent services that communicate with each other (often via APIs). This is relevant for very large applications, those that require high independent scalability for each service, or when different teams work on different parts. It is more complex to implement than a monolithic architecture.

We use strong authentication mechanisms like OAuth 2.0, JSON Web Tokens (JWT), or secure session-based systems. For permissions, we implement role and permission systems (RBAC) to finely control what each user can do or see.

Yes. Our backend developers in Lausanne can carry out a audit of your current backend, identify performance bottlenecks, security vulnerabilities, or architectural issues, and propose an optimization or refactoring plan. Contact us for a backend development quote.
