During February 2025, Vrelk focused on stabilizing the DeepGram speech-to-text file upload workflow within the abeiro/HerikaServer repository. Addressing a persistent 400 Bad Request error, Vrelk refactored the backend API integration to use cURL in PHP, improving error handling and file upload reliability. The work included targeted code cleanup, enhancing readability and maintainability of the upload logic. By resolving this bug, Vrelk reduced user-facing errors and support tickets, laying a stronger foundation for future DeepGram integrations. The project demonstrated depth in backend development, API integration, and file handling, with a clear emphasis on robust, maintainable engineering solutions.
