Worked on the yaap/ota-info repository to implement a certified fingerprint version update for the Cancunf application, focusing on configuration management and version control using JSON. The update involved bumping the cert.json fingerprint from version 29.0 to 30.0, ensuring alignment between the Cancunf and Sunny components. This process was managed through two traceable commits, enhancing auditability for over-the-air deployment and device certification workflows. The work strengthened the integrity of OTA processes and supported ongoing certification cycles. By coordinating changes across modules and maintaining clear version history, the developer contributed to robust configuration practices and reliable deployment pipelines within the project.
