Why Backend Development Matters

Backend development is the engine behind all the web apps and websites you interact with daily. It deals with data storage, server management, and ensuring that everything works smoothly behind the scenes.

According to the Bureau of Labor Statistics, computer and IT occupations are expected to grow by about 11 per cent over the next decade.

This growth means there’s a strong demand for people who understand how to build and maintain the backend of digital systems.

Learning backend development not only enhances your technical skills but also opens up career opportunities.

Whether you’re interested in starting your own business, joining a tech startup, or working for a large company, the ability to create efficient and secure backend systems is a valuable asset.
