I build reliable dbt data warehouses and BI products from source integration to production support.
Russian FederationWhat I'm looking for
At M Tech, I build and operate the end-to-end BI and data environment for a mining company, from source integration and layered warehouse modeling to dbt development, data quality, deployment, and production support.
I rebuilt inventory analytics into a PostgreSQL and dbt warehouse integrating two ERP systems and 39 source tables. The solution includes 50+ dbt models for 100k+ inventory items across 21 organizations, reducing BI refresh time from minutes to 12–17 seconds.
I’ve also delivered ticketing and HR analytics products, including 25+ dbt models for 320k+ tickets and 30+ HR models covering 9k+ employee records. I build traceable data-quality workflows, including 300+ automated tests that preserve invalid source data for correction while protecting reported metrics.
Before leading BI engineering, I delivered stakeholder-facing dashboards and analytics for production, inventory, operations, and equipment. I enjoy turning business problems into clear metric definitions and maintainable data products.
