## About

```text
At GRID DYNAMICS, I deliver data engineering solutions for enterprise client engagements across data pipelines, platform modernization, and distributed processing. For a HelloFresh engagement, I rewrote a Spark/MLflow workflow and reduced a processing run from approximately 22 hours to approximately 1 hour.

Since July 2026, I've worked on a Caterpillar engagement involving unstructured data processing and LLM-related workflows, and explored AI-agent workflows for code review and debugging using vector-database-backed context and memory. Earlier, I developed ground-station software and machine-vision capabilities for UAV applications at PRIDEAVIONICS.
