She owns end-to-end forecasting processes—from data cleansing and outlier detection to model optimization and KPI-driven performance analysis—while closely integrating local market insights to improve accuracy. Her background in biological sciences and advanced statistics gives her a strong grounding in experimental rigor and applied analytics across R, Python, Databricks, SQL and Snowflake. She has built practical tools including an R Shiny app for standardized product strategy decisions and an image-detection prototype for packaging logo recognition. A regular mentor and communicator, she presents findings to stakeholders and even spoke at Mobile World Congress, underscoring her ability to translate technical work into business impact.
