I started my career in international logistics and developed a strong foundation in multimodal transportation, rail operations, carrier coordination, and cross-border supply chain management. Over time, I became increasingly focused not only on how operations run, but on how they can be improved through analytics, automation, and better decision-making. Today, I combine logistics expertise with analytical thinking and hands-on work in Excel, Python, reporting, and AI-assisted problem solving. I enjoy building practical solutions that help teams see clearer, work faster, and make better operational and management decisions. What motivates me most is solving complex business problems. I like diving into current operational challenges, understanding what is really happening beneath the surface, and finding solutions that are both practical and strategically right for the future. Whether it is improving visibility, automating repetitive work, structuring reporting logic, or supporting planning with data, I aim to bring clarity and value. I see technology not as a separate field, but as a tool that can make operations smarter. That is why I am actively developing my skills in Python, automation, and data analysis while building on my core experience in logistics and transportation.
