Hey there! I'm a Senior Quantitative Engineer with 9+ years of experience in financial services. I love working with mathematical modeling, building scalable applications in Python, and leading teams to create innovative solutions for complex financial challenges. When I'm not diving deep into code, I enjoy exploring new technologies and solving interesting problems. You'll find me at Pilates, on the sports field, or at a new restaurant!
