Message

At Wildberries, I led the team responsible for a product-search platform serving 50M+ SKUs at around 150k RPS peak. I re-architected the search read path to handle sale-event traffic at roughly five times the daily baseline while keeping p99 under 90 ms, and designed an indexing pipeline that cut update-to-searchable lag from minutes to seconds.

I also built production AI systems at Wildberries, including agent workflows, MCP servers, and RAG pipelines, and helped standardize AI development across teams. At Quadcode, I built internal developer-platform products for deployment and infrastructure governance, and led a team of seven engineers.
