What I'm looking for

I am seeking senior data engineering or architecture roles focused on designing and optimizing data warehouses, tackling R&D and high-load ETL challenges, and contributing as a technical lead or consultant within collaborative, engineering-driven teams.

I am a professional data warehouse developer with seven years focused on data warehouses and eight additional years developing Oracle PL/SQL for the banking sector. I excel at both architecture design and hands-on development across cloud and on-prem environments.

I have built data warehouses from scratch and developed storage and ETL architectures at companies including Tripledot Studios, Wargaming and S7 Airlines. Key achievements include creating a software package for a complex ETL dispatcher, developing a Data Quality module and universal IDMAP fabric, and optimizing high-load processes and queries across large-scale systems.

Currently I work as a self-employed consultant and developer, delivering data engineering, architecture and Scala development in outsource/outstaff formats. I enjoy R&D tasks, performance optimization, and taking ownership of end-to-end data solutions.
