I have experience building large-scale batch and real-time data platforms that process terabytes of data daily. Beyond implementing pipelines, I focus on improving reliability, performance, and engineering practices by leading large-scale migrations, optimizing compute costs, establishing coding standards, and mentoring engineers.

In addition to data engineering, I build backend services in Python (FastAPI) and Go (Gin), and develop AI agents and MCP servers to automate workflows across data platforms.

I enjoy solving complex infrastructure challenges end-to-end, from architecture and implementation to observability, data quality, and developer productivity. I'm looking for a role where I can design scalable data platforms, drive technical decisions, and contribute to a strong engineering culture.

Employment History

Senior Data Engineer at VK 2026 - 2026
- Built end-to-end resource monitoring for team YTSaurus pool (CPU, RAM, calculation durations): metric collection, data marts and aggregation across time, users, operations and tables. Created dashboard (BI) for ongoing control and investigations. - Ran a consumption audit and drove optimizations for the most CPU-intensive recurring jobs; achieved a sustained ~ 1.5% CPU reduction at the pool level (about a thousand cores), with individual pipelines improved about 15%. - Executed a large-scale migration to new target path layout: moved ~ 2000 directories and ~ 200k nodes (~ 20 PB) with no data loss and no required to stop regular ETL.
Senior Data Engineer at Yandex 2023 - 2026
- Designed, developed, and maintained data supply pipelines (batch processing up to 1TB daily increments and real-time delivery). Using query optimizations, reduced the average SLA for the group’s data marts by approximately 3 hours (daily scale). - Gathered requirements, designed architecture, implemented solutions, set up monitoring and testing, ensured data quality and increase data mart usage by 70%. - Examined the accuracy, completeness and coherence of more then 20 dataset using data analysis and data profiling approaches. - Conducted comprehensive code reviews, raising code quality in the data warehouse. - Authored SQL code style guide and company-wide recommendations for query optimization to boost performance and maintainability (Guide was using by 5 business units in the company). - Developed and implemented AI-tool for creating table’s metadata using LLM. - Conducted technical interviews (focused on SQL) and mentored junior engineers and trainees. - Collaborated with more then 6 cross-functional teams to deliver and support highly available data infrastructure. - Provided a full pipeline cycles (data ingestion, data transformation, integration across multiple platforms)
