I’m a Senior Systems and Hardware Test Automation Engineer with 7+ years of experience bridging complex physical hardware, firmware, and scalable software architectures. I focus on building Python-based test automation and Hardware-in-the-Loop (HIL) environments that make real systems easier to validate, safer to operate, and faster to improve.

At NPK VIP Ekaterinburg, I architected and led the SDLC for end-to-end HIL automation pipelines. I deployed multithreaded backend systems using Python, C#, and PostgreSQL, replacing manual operational workflows and reducing testing cycle times by 55%.

I also led cross-functional efforts to ingest and integrate continuous high-frequency data streams from CAN, J1939, MQTT, Modbus, and Serial into a unified backend. Beyond integration, I designed robust PostgreSQL/SQLite database architectures and secure, high-availability backend services to store and query telemetry for enterprise software environments, supporting seamless hardware telemetry integration.

To strengthen confidence without relying on live production systems, I developed custom virtual ECUs and automated plant-model emulators to simulate edge cases and inject hardware faults. I engineered a high-capacity data analysis platform to process and query 100M+ telemetry records and implemented real-time UI rendering for 3.5M+ data points per view, which secured major client contracts through demonstrated scalability; I also built a high-throughput aggregation service that cut processing and reporting from 3 days to 1 day (66% faster). Earlier, I performed Root Cause Analysis (RCA) on automated production lines at Unilever to implement long-term technical fixes and improve uptime, and I completed protocol analysis, reverse-engineering, and diagnostics work at Super Truck—reducing fault-identification and system debugging time by ~40% while performing hands-on hardware integration and data acquisition.
