What I'm looking for

I seek a leadership or senior engineering role building scalable data platforms and backend systems, in a collaborative Agile team focused on reliability, observability, and measurable performance improvements.

I am a Senior Software Engineer and Data Platform Lead with over 10 years of experience building high-load systems and data platforms for international markets.

I blend Data Engineering (ETL/ELT, Airbyte, Dagster, Redshift, PostgreSQL) with backend development in Python and .NET to design reliable, performant pipelines and services.

As a technical lead I have driven cross-functional teams, established architecture and coding standards, and improved delivery through Agile practices and automation.

Notable achievements include designing SellerMetrix analytics modules, building fault-tolerant ETL pipelines, reducing data sync and query times, and implementing deep monitoring that improved uptime.
