SUMMARY
Data Analyst with 4 years of experience analyzing large volumes of seller data on a marketplace. I have experience in business process automation; in particular, I developed an AI assistant (LLM, vector search, semantic analysis) for ad classification, which significantly reduced manual processing time and increased operational efficiency.
I regularly participate in training camps and mentoring programs, demonstrating my commitment to continuous professional development in the field of data analytics. I am eager to apply my expertise in data analysis, AI-powered solutions, and process automation to deliver impactful, data-driven solutions that directly enhance business outcomes.
