Turning production chaos into seamless flow.
I'm a Production Planning & Inventory Control specialist with over five years of hands-on experience keeping manufacturing operations balanced, efficient, and responsive. My career journey has taken me across several manufacturing companies where I've owned the full planning cycle — from demand forecasting and master scheduling to material planning and inventory optimization.
My work philosophy is simple: let the data decide. I believe every stockout, bottleneck, and delay tells a story, and the numbers point the way to the fix. I focus relentlessly on efficiency, waste reduction, and building processes that scale.
