Our expertise

Robust backend design and programming (Laravel, Python FastAPI, Node.js) for high-performance web and mobile applications.

The backend is the invisible engine that ensures security, business logic, data management, and communication between your various systems. Geekworkers designs custom backends and APIs tailored to your business requirements. We primarily use Laravel (PHP) for complete business architectures, FastAPI (Python) for microservices and AI integration, and Node.js for asynchronous and real-time streams.

Our engineers ensure OWASP compliance, optimization of database queries (PostgreSQL, MySQL) and scalability of your infrastructure hosted in Switzerland.

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.
