Why learn COBOL ?

COBOL is often seen as a language of the past… and yet, it remains at the heart of critical systems used by banks, insurance companies, and government agencies worldwide. A huge portion of financial flows still relies on COBOL code, sometimes written decades ago.

The problem? Very few developers still know how to read, maintain, or evolve it.

For a junior developer, this is a rare opportunity. While most profiles compete for the same modern stacks (JavaScript, React…), COBOL positions you in a much less competitive market, yet an extremely strategic one.

Learning COBOL isn't just about learning a language: it's about understanding how robust, stable, and critical systems work, designed to last over time.

And above all, it's a skill that can open the door to well-paid assignments, in environments where companies struggle to recruit.

By the end of this course

You will be able to understand and write COBOL, and above all, position yourself in a market where these skills are rare and sought after.
