Summary

I am a Demand Planner with several years of experience in sales forecasting, inventory management, and supply chain process optimisation. I combine a strong analytical mindset with a practical understanding of business — delivering forecasts that not only match the numbers but support strategic decision-making.

I have worked across local and international structures, including e-commerce, export, and traditional retail channels. I am well-acquainted with the S&OP environment and collaborate effectively with sales, production, and marketing teams.

Currently, I am responsible for forecast accuracy analysis and participate in implementation projects (NPD, rebranding). I increasingly take ownership of decisions that influence the strategic direction of the business. I continuously broaden my scope — both operationally and cross-functionally.

I enjoy improving processes, identifying inefficiencies, and asking the right questions that lead to better solutions. I am seeking a role where I can further develop my strategic capabilities and make an impact across the value chain.
