What information and data types were processed on your services in the previous project?

In previous projects, the following information was usually processed on services:

• User data: names, email, passwords (stored with hashing), settings.
• Transaction data: orders, payments, operation statuses.
• Logging and metrics: service operation events, errors, response times.
• Temporary data: sessions, cached results.

Data types included strings, numbers, dates, boolean values, as well as complex structures (JSON, protobuf) for data transfer and storage.

For example, an authentication service might process email (string), password (string, hashed), tokens (string), last login time (timestamp).
