ETL pipeline development
For a PHP developer, ETL pipeline development involves creating the systems and processes that Extract, Transform, and Load data from various sources into a centralized repository, such as a data warehouse or another database. This is a crucial function in data-driven organizations, enabling business intelligence, analytics, and reporting.

The primary responsibility is to build and maintain robust, efficient, and reliable data pipelines. This includes writing PHP scripts to extract data from sources like third-party APIs, databases, flat files (CSV, XML), or message queues.

Finally, the developer is responsible for loading the transformed data into its target destination, ensuring performance and data integrity throughout the process.

Success in this specialization requires strong backend development skills, including:
- Advanced proficiency in PHP and SQL.
- Experience with different data formats such as JSON, XML, and CSV.
- Knowledge of job queues (e.g., RabbitMQ, Redis) and schedulers (e.g., cron) for automating pipelines.
- Familiarity with database design and data modeling principles.
- Experience working with RESTful APIs and other data sources.
