Challenge

Kering's luxury retail warehouses faced a classic inventory dilemma: minimize average stock levels to reduce carrying costs while keeping missing sales below acceptable thresholds. Static replenishment rules could not adapt to seasonal demand shifts and promotional events, leading to either excess inventory or costly stockouts.

Approach

Explored and developed a dynamic replenishment algorithm with statistical demand modeling and reinforcement learning.

Challenge

Bracco Suisse needed to improve diagnostic confidence in contrast-enhanced ultrasound examinations by automatically classifying liver lesion types from noisy, low-contrast CEUS images where temporal contrast dynamics and image artifacts make standard classification approaches unreliable.

Approach

Designed custom neural network architectures for CEUS image processing, implementing domain-specific augmentation strategies that account for ultrasound artifacts, contrast agent dynamics, and temporal perfusion patterns. Built a preprocessing pipeline tailored to the unique characteristics of contrast-enhanced ultrasound data.
