I developed an end-to-end test automation architecture from scratch for an ECR application on a physical POS device, SmartPeak. I used Katalon, Appium, and Groovy, and designed dynamic XPath locators and modular custom keywords.
I also built a Linux-based home security system with Raspberry Pi, C++, and TCP/IP sockets, and created a media-company database with a responsive web interface and an MS SQL Server backend.
