Constantin Kozin

I’m a Reporting & Data Analyst with 6+ years of experience in financial operations, reporting, and process automation within a large enterprise environment. I build Excel- and Python-based reporting workflows that analyze operational performance and support management decision-making with data-driven insights.

In my current role, I developed automated reporting and Excel workflow solutions using Python, SQL, and openpyxl to reduce manual workload and streamline repetitive data-processing tasks. I extract and validate data using SQL and large Excel datasets, then prepare dashboards and executive reports under tight deadlines—even within restricted technical infrastructure and legacy system limitations. I also mentor colleagues and share automation and reporting best practices across departments, and was promoted to Expert for contributions in analytics, process automation, and operational improvements.

Before that, I transitioned from front-line support into training and quality, building onboarding and upskilling programs for customer support agents. I analyzed training effectiveness, maintained green performance metrics, and helped develop a high-performing team from scratch through coaching, feedback, and performance reviews.
