About
My work spans fraud detection (I built a dropper-detection model with LightGBM/XGBoost that improved F1 from ~0.49 to ~0.66 by adding behavioral session features), customer segmentation (KMeans/DBSCAN clustering across millions of retail clients, deployed as a Dash service), and personalized deposit pricing with A/B testing. Before ML, I spent four years at SLB (Schlumberger) as a Field Engineer and later as Product Owner of an internal operational platform — so I've seen both the operational and technical sides of building something that actually gets used. I studied Mechanical Engineering (BEng) at the University of Bristol, and I'm trilingual in Kazakh, Russian, and English.
