LLC CARDSMILE (Moscow, Analytic Service Provider) 2014– 2015 Customer Analyst

Worked as an analyst in a start-up that provides customer analytics for Retail clients.

  • Implemented a BI reporting system for a retail chain (~280 stores/~2 million clients per year/~1 million transactions per

    year). I drove an entire project myself (DWH architecture, ETL, reports) with a help from external BI consultants. New BI system consolidated data from multiple sources (CRM, sales and online store), in multiple formats (SQL database, json, xml) and used SAP Business Objects + Pentaho+ PostgreSQL.
    Impact: the implementation of a BI system solved data inconsistency problems and reduced time spent on reporting.

  • Built data mining models for clients. Developed Next-Product-To-Buy models for multiple clients: a grocery chain (~8 million of active customers per year), toys stores, jewelry stores.
    Impact: switching from non-targeted campaigns to personal offers increased marketing campaigns response rates by 5%.
