• I am working with Trendyol on the HCM project with the followings technologies. This project, with more than 10,000 users, manages personal data related to:
• Payroll and premium calculations for users,
• Leave usage and entitlements,
• The status of purchased training programs.

Workflows are utilized for scenarios requiring user approval or rejection. RabbitMQ is employed for sending messages, emails, and Slack notifications to users.

Background services handle situations requiring daily or monthly calculations.

Due to the high number of users, LINQ queries and methods are designed to operate efficiently. Data is retrieved from Redis instead of the database when it is not strictly necessary.
