Lead Staff Data Engineer at Blitz
As a problem-solving enthusiast, I’ve always been driven by curiosity and a desire to tackle technical challenges that teach me something new. My passion for data started early, and I’ve since explored it in many forms — from sequential and spatial data to images, audio, and BI systems. Now working in the exciting world of gaming, I build large-scale data systems that power analytics, in-game features, and machine learning for millions of players. With a strong R&D mindset, I enjoy combining deep technical work with creative thinking — whether it’s optimizing pipelines, experimenting with models, or enabling better decisions through data. I thrive in environments where I can learn continuously and push the boundaries of what data can do.
