Calculation Reminders System
Advanced system for calculating payment reminders for millions of records with efficient caching mechanisms.
As a Core Features Developer at Bilendo GmbH, I was responsible for developing and enhancing a sophisticated calculation reminders system that processed millions of payment records efficiently.
The system needed to handle large volumes of data while maintaining performance and reliability. To achieve this, I implemented advanced caching mechanisms using Redis and Elasticsearch, which significantly improved response times and reduced server load.
The project involved complex business logic for payment calculations, reminder scheduling, and notification delivery. I worked closely with the product team to ensure the system met all business requirements while maintaining technical excellence.
