I have led end-to-end annotation projects, developed SOPs to improve accuracy, and mentored teams to consistently achieve 98%+ quality standards. My background in computer science and data analysis allows me to optimize workflows, collaborate effectively with data scientists, and provide actionable insights to enhance model performance. I am passionate about maintaining high data quality, streamlining processes, and contributing to impactful AI solutions.
