During April 2026, contributed to the webitel/engine repository by delivering a feature that enhanced appointment data visibility and reliability. Developed and implemented a default sorting mechanism for appointment records, ensuring that the most recent entries appear first in both API responses and UI listings. This involved adjusting API routes and modifying backend appointment handling logic using Go, with a focus on API and backend development best practices. The changes improved data freshness for end users and were validated through a pull request and commit-based workflow, demonstrating disciplined version control and clear traceability throughout the development and deployment process.
