About me

I'm a full-stack data scientist with a passion for turning complex data into actionable insights that drive business impact. With a solid foundation in both technical and business disciplines, I’ve designed and deployed end-to-end data solutions—from integrating multi-source datasets and building predictive models to developing interactive dashboards that support real-time decision-making. Turning complex problems into simple, beautiful and intuitive designs.

My background spans roles in marketing analytics, customer segmentation, and financial forecasting, and I’ve led projects ranging from a churn prediction model at Alexander Tutoring to an LLM-enabled job application tracker. I thrive on solving challenging problems with innovative techniques and continually strive to expand my expertise across the entire data workflow, ensuring that every insight I uncover not only informs strategy but also creates tangible value.
