Hi, I’m Sahana Sarangapani. I’m a Software QA Engineer with over 7.5 years of end-to-end testing experience across embedded systems, IoT products, and networking technologies. I validate hardware–software integrated solutions, including Web GUI, wireless modules, RS232/485, Bluetooth/BLE, Modbus, QoS, SNMP, NTP, HTTPS, and networking protocols like TCP/IP, UDP, TLS, and TLS cipher compliance. I design scalable automation frameworks in Python, build Selenium-based UI tests, and run CI/CD pipelines with GitLab CI/CD and Kubernetes runners. I enjoy turning complex test scenarios into reliable automation, collaborating cross-functionally to improve release quality, and improving security and performance of devices. My focus areas include firmware and image validation, boot verification, OTA behavior, bootloader testing, and security checks (TLS, certificates).…Hi, I’m Sahana Sarangapani.
