About

With a Master of Science in Mobile and IoT Engineering from Carnegie Mellon University, I currently contribute as a Software Engineer at TikTok, focusing on ad monetization through A/B testing platforms using Golang. Collaborating with data science and marketing teams, we optimize brand lift studies and enhance marketing strategies through robust backend infrastructure development. Previous experiences at Amazon and AWS strengthened my skills in API development, backend logic implementation, and cross-functional coordination. Passionate about leveraging expertise in automation and data-driven insights, I aim to drive impactful technological advancements in dynamic and collaborative environments.
