  • I had the opportunity to lead a fantastic team of 6 engineers, and together, we achieved a 20% reduction in testing cycle time by optimizing our test plans and implementing automation frameworks.• One of the important activity we worked on was enhancing a Python-based Automated Test Framework (ATF), which boosted LTE and NB-IoT module testing efficiency by 25%.• I also automated the integration of the Saleae Logic Analyzer with our test workflows using Python APIs, making our debugging process much faster and more efficient.• Another significant project was conducting power profiling tests with the Otii Arc Pro analyzer, where I identified several optimizations that improved device power consumption.• I had the chance to work on climatic chamber tests ensuring our devices performed under extreme temperature conditions including both +85°C and -40°C.• Using Qualcomm tools (like QXDM, QUTS, PCAT and QPST), I helped test Qualcomm chipset based devices and ensure they met the highest performance standards.• A big part of my role also involved collaborating with cross-site teams to manage project activities, including task allocation, resource training, weekly status meetings, and providing support in ongoing activities including MNO certifications.• Reviewed code with teammates to ensure quality and compliance, while mentoring and training new team members to help them grow and excel in their roles.• Took full ownership of completing all tests within a suite, while designing, developing, and executing system tests for various UART configurations (4/6/8 wire, including RI, DCD, DSR, DTR, TX, RX, RTS, CTS lines) and different MUX scenarios.• Integrated and tested LTE Cat M1 and NB-IoT modules using Nutaq PicoLTE, ensuring seamless functionality and reliable performance. Show less • I developed and executed several key test suites, such as the Data Calls and Internet Suite, which helped us improve testing speed and reliability by 10%.• I worked on enhancing libraries for the CMW290/CMW500 signaling testers, which helped streamline our test processes and increase their accuracy.• I focused on validating USB drivers, using tools like USBCV to ensure flawless performance across various device configurations.• One of the highlights was performing remote testing with international MNOs like Verizon, AT&T, and Vodafone to ensure that everything was compliant with 3GPP standards. Show less • A major part of my work involved conducting drive tests to evaluate cellular module connectivity in real-world environments, ensuring that our devices could handle various network conditions.• I also worked on integrating power supplies into our test frameworks, allowing for better real-time power monitoring and control, which improved testing efficiency by 25%.• Another achievement was enhancing libraries for the Anritsu Signaling Tester, which helped reduce manual testing time and improved overall testing accuracy. Show less • In this role, I focused on improving Voice Calls and SMS test suites, which helped enhance the reliability of our cellular modems by 10%.• I also created a Python-based GUI using the Qt framework, which simplified the testing process for our team, enabling us to run complex workflows with just a few clicks.• I worked closely with the team to diagnose and resolve issues that arose during testing, ensuring the highest quality for our products.• Additionally, I optimized the testing framework libraries, which improved maintainability and speed, resulting in more efficient test cycles.
