• Implemented first learning to rank model in the company that lead to 4.3% rise in booking conversions.• Led a cross-functional team of engineers to develop GenAI platform to allow anyone including non-technical people to create chatbots. In less than ten months, developed the product from scratch and scaled across the TUI Group achieving 25%+ enterprise-wide adoption within six months six months after the launch of initial PoC.• Led company wide group (with Engineers from five teams) about resiliency of machine learning models. Developed specific recommendations. Practically demonstrated those recommendations in two ML projects. Created a dashboard to track projects across the company. • Led a cross-disciplinary team to develop integrated machine learning platform based on different AWS services. Project delivered on time with demonstrated application on a product recommendation feature that led to €2.3 annual margin uplift.• Led the initiative to make MLOps platform multi-tenant. Worked with teams across TUI to build a consensus on design that support all machine learning projects (including both the customer facing and internal operational models).• Delivered GenAI powered feature to enhance discoverability of data assets to accelerate the development of AI capabilities.
