Tell about the business vertical you are in.

I work in the business vertical of financial technologies (FinTech). The main focus is on developing systems for online payments and transaction management. This includes integration with banking APIs, ensuring data security, and compliance with regulatory requirements such as PCI DSS.

Within this vertical, high reliability and scalability of services are important, as they handle a large number of operations in real-time. It is also necessary to consider the specifics of working with different currencies and international payment systems.

Experience in this field helps to better understand security requirements, error handling, and monitoring, which are critical for financial applications.
