Summary

  • I am an automation developer and QA engineer specializing in Python-based systems for data processing and quality assurance. With hands-on experience across diverse environments, I have built robust automation frameworks and backend services that enhance testing efficiency and product reliability.
    I have independently set up Robot Framework environments and developed web crawling and AWS CloudWatch log collection modules using Selenium and boto3. These projects laid the foundation for data-driven quality validation, allowing me to move beyond manual testing and implement automated data collection and processing pipelines.
    My backend development experience includes building web services using Django, Flask, and FastAPI. Notably, I developed a GNSS accuracy verification tool using pynmea2, Flask, and FastAPI, which involved parsing and visualizing NMEA data—strengthening my real-time data handling and analytical capabilities.
    In the field of software testing, I spent three years conducting automated validation for WW’s OCU devices, gaining deep insight into industrial testing challenges and issue analysis. I also utilized ALM tools such as Jira and Codebeamer to manage issues systematically and improve development and QA workflows.
    To reinforce my expertise, I earned the ISTQB CTFL certification and the ADsP (Advanced Data Analytics Specialist) credential. I also completed the KDT Big Data Expert Training Program, equipping me with the skills to integrate data analytics with quality assurance.
    Looking ahead, I aim to build systems that quantify and predict product quality using processed data—moving beyond defect detection to proactive quality improvement. As a developer who understands data and a QA engineer who protects product integrity, I am committed to contributing to the delivery of trustworthy, high-quality solutions.
