About Alexandr

I design and build data pipelines for financial analytics, with a focus on portfolio and ESG data.

My work typically involves integrating complex datasets (holdings, benchmarks, ESG providers), transforming them into reliable, analysis-ready outputs, and ensuring consistency between underlying data and reported figures.

I have a strong background in systematic investing and understand the full data-to-decision chain — from raw data ingestion and signal generation to portfolio construction and reporting.

I am particularly comfortable working in imperfect data environments, debugging inconsistencies, and aligning business logic with actual outputs.

Tech stack includes Python, SQL, Databricks and PySpark.
