At Asteriosoft, I develop backend and data-processing components for a real-time AdTech analytics platform. I redesigned reporting around pre-analyzed ClickHouse and PostgreSQL data, bringing full-day report generation to about two minutes.
At Eastmining Corp, I was the sole Senior Engineer and architecture owner for a real-time monitoring platform handling about 1K RPS. I integrated LLM agents into workflows and helped scale infrastructure through traffic growth without SLA degradation.
At EPAM Systems, I led backend development for American Stock Transfer & Trust, including a monolith-to-microservices transition that reduced build and deployment time for key modules by about 40%. I also built a personal LLM-driven resume screening service using LangGraph4j, PostgreSQL, and human-in-the-loop review.
