Serhii Savin: Applying Data Science for Fairness, Efficiency, and Social Impact

Serhii Savin is a data scientist whose work demonstrates how advanced analytics and machine learning can be applied responsibly to create measurable economic and societal value. Currently serving as a Data Scientist at Lyft, Savin operates at the intersection of artificial intelligence, large-scale data systems, and ethical technology deployment—an alignment that closely reflects the mission of the International Institute of Computer Science Professional Association (IICSPA).

With a strong academic foundation that includes a Master of Arts in Economics with a minor in Data Science, Savin brings rigorous training in advanced statistics, supervised and unsupervised machine learning, and quantitative modeling to real-world challenges. His technical expertise spans Python, PySpark, R, SQL, and Tableau, enabling him to design scalable analytical solutions across complex data ecosystems.

At Lyft, Savin has played a key role in improving fairness and operational efficiency within ride-sharing systems. He spearheaded a highly complex toll cost reconciliation initiative that reduced annual toll discrepancies by millions of dollars. This effort not only optimized internal cost controls but also ensured more accurate rider pricing and fairer driver compensation—demonstrating how data science can directly support ethical outcomes in large consumer platforms.

Beyond cost optimization, Savin develops advanced predictive models that enhance ride-matching efficiency and customer satisfaction. His prior work at Appflame further illustrates his ability to translate analytics into business impact. There, he designed unit-economics models for the company’s “streams” feature, achieving a 15 percent cost reduction and accelerating the feature’s break-even timeline to just four months. The initiative contributed to a measurable five percent increase in overall application revenue, underscoring his capacity to align technical rigor with strategic business goals.

Equally significant is Savin’s commitment to strengthening the global technology community. He actively mentors early-career data scientists and analysts through the Ampersand Community and supports onboarding and professional development for new engineers at Lyft. Through this sustained mentorship, he contributes to building a more capable, ethical, and resilient STEM workforce.

Savin’s impact extends well beyond the private sector. In collaboration with Ukraine’s Ministry of Digital Transformation, he co-developed two foundational courses in data analytics covering Excel, SQL, and Power BI. These courses—among the first of their kind available in the Ukrainian language—were offered entirely free of charge, removing both financial and linguistic barriers to entry. The programs have reached thousands of learners and received hundreds of positive reviews, marking a significant contribution to accessible data science education during a critical period of digital transformation.

Through a career defined by technical excellence, ethical application of data, and sustained community engagement, Serhii Savin exemplifies the role of a modern computing professional: one who advances innovation while ensuring technology serves society in a fair and inclusive manner. His work reflects the values IICSPA seeks to promote—responsible innovation, professional integrity, and positive global impact.
