A back-end developer builds and maintains the server-side of a web application. This includes writing the application logic, managing the database, building APIs, and ensuring the entire system is secure, fast, and scalable. They are the architects of the application's "engine".

The front-end is the part of the application the user sees and interacts with (the user interface). The back-end is the server, database, and application logic that works behind the scenes to power the front-end. The back-end handles tasks like user authentication, data storage, and business calculations.

There is no single "best" language. The right choice depends on the specific needs of the project. PHP is great for content-heavy sites, Python is excellent for data science and rapid development, Java is a powerhouse for large enterprise applications, and Node.js is fantastic for real-time applications and speed. Our experts can help you choose the right tool for your job.

An API (Application Programming Interface) is a set of rules and tools that allows different software applications to communicate with each other. In web development, the back-end API is what allows the front-end (e.g., a mobile app) to get data from and send data to the server.

 architectural style where a large, complex application is broken down into a collection of smaller, independent services. Each service is responsible for a single piece of business functionality. This approach can make applications easier to scale, maintain, and update.
