South KoreaWhat I'm looking for
I’m a data and analytics professional with 8+ years of experience turning complex datasets into insights that drive revenue, efficiency, and strategy.
Currently at Criteo, I specialize in Supply Side Platform (SSP) analytics—optimizing publisher monetization, leading supply path optimization, and building automated reporting workflows. My work has delivered measurable impact, from 10%+ revenue growth through floor price optimization to 12% performance gains via supply path analysis.
Previously at Bigin, I developed ML-based customer analytics for e-commerce clients, including RFM segmentation, LTV forecasting, and recommendation engines served via API—contributing to $5M+ in revenue and securing long-term client retention.
Earlier roles at SAP Korea and Seagate Technology gave me strong foundations in marketing data automation, CRM optimization, and large-scale process improvement.
I thrive at the intersection of data, business, and technology—using SQL, Python, and BI tools (Tableau, Power BI, Redash, Dash) to bridge teams and turn analytics into actionable strategies. I’m passionate about solving problems, building scalable solutions, and helping organizations unlock value from their data.
