With over 15 years of experience in software development, I am passionate about automation, innovation, and breaking through paradigms to create streamlined solutions, improving efficiency and lowering costs. My expertise lies in developing robust applications and processes that meet and exceed client expectations. I enjoy collaborating with local, cross-site, and cross-functional teams, leveraging my communication skills to synchronize efforts and drive projects forward. My most recent accomplishment at BlackBerry was the development of a web application that reduced weekly test result triaging time from 2 days to 2 hours, enabling efficient processing of over 1 million test results each week.
