Summary
I am a data scientist and AI product builder with 6+ years of experience across marketplaces, banking, and e-commerce.
My work sits at the intersection of analytics, experimentation, machine learning, and software engineering. I partner closely with product and engineering teams to define metrics, design experiments, ship AI-powered tools, and turn data work into practical product outcomes.
Current Focus
At SMG Swiss Marketplace Group, I lead the real estate data science roadmap from both product and technical angles.
Current areas of work:
- cross-functional data science initiatives for B2B and B2C marketplace products
- multilingual generative AI applications, automation tools, and chatbot services
- performance prediction and recommendation systems
- A/B testing and simulation-based decision support
- mentoring junior teammates and supporting AI adoption
