💼 What I Worked On
-
Focused primarily on the deskphone features of the product. Developed proprietary drivers for electronic-hook-switch protocols (DHSG, MSH and HSL), enabling the SWD5000 to communicate seamlessly with a diverse array of deskphones, expanding product comptability horizons.
-
Architected and implemented a sophisticted test automation solution by combining integration testing, hardware-in-loop testing and continuous integration and delivery (CI/CD). The solution was designed to run tests extensively on a daily basis, triggered by developers, as well as scheduled nightly tests.
