Introduction
As a dedicated Manager of Marketing Mix Modelling with over 7 years of experience in the market research industry, I thrive on transforming data into actionable insights that drive strategic decisions. My expertise lies in leveraging advanced analytics to optimize marketing strategies and enhance business performance. I bring a strong technical foundation to my role, with proficiency in R and Python that allows me to deep into data and uncover trends that might otherwise go unnoticed. My background also includes experience as a Teaching Assistant and Researcher at the university level, where I improved my analytical skills and developed a passion for data science. In my current role, I am not only focused on delivering marketing mix analyses but also on nurturing and developing the analytical talent within my team. I am committed to fostering a collaborative environment where creativity and precision go hand in hand, ensuring that we continuously push the boundaries of what data can achieve. Passionate of data science and business strategy, I am always open to connect with fellow professionals and explore new opportunities to advance the field of marketing analytics.
