Hello, Witold1 is here! You might recognize me from my involvement in various analytical projects, insightful blog comments, and captivating DataViz products. Below, you'll find a selection of open projects that I believe are worth sharing from my previous experiences.
If you're interested in collaborating on projects that require joint expertise or need recommendations regarding data sources and data processing, don't hesitate to reach out.
Currently, I am excelling in Sales, Strategy, Operations, and Business Intelligence practices at a local automotive business across American Midwest, where I optimize sales of niche cars with data-driven strategies and maintain analytical infrastructure. Prior to this, I held a position in Advanced Business Intelligence team at RouteOne, the leading North America Automotive FinTech Platform headquartered in Detroit metro. Prior, I have gained valuable experience in Advanced Analytics and Data Science team while working for prominent R&D Intelligence consulting firm in Europe.
