About

Senior .NET developer based in Krasnodar with 4+ years building production-grade systems. I work with the full stack: .NET Core, Vue.js, Blazor, MAUI Hybrid.

Deep experience in microservice architecture, event-driven systems on RabbitMQ, and performance optimisation — reduced memory consumption by 40%, SQL query speed by 70%.

Recently implemented LLM/RAG for an intelligent knowledge base and integrated OpenCV for medical document processing. Currently studying Go for high-load systems.
