In January 2026, Lena Saraba contributed to the SulePostar/finetica repository by delivering three features focused on financial data accuracy and invoice user experience. She developed an Exchange Rate data model and migration using Node.js and Sequelize ORM, enabling daily storage of currency rates with robust database structure. Lena also improved invoice workflows by enabling PDF display within the application’s DocumentDetails component, leveraging React for front end enhancements. Additionally, she automated daily currency updates through a GitHub Actions workflow written in JavaScript and YAML, incorporating error handling and environment management to ensure reliable backend operations and maintainable DevOps practices.
