eDreams ODIGEO | Jun 2022 - Present

Data Scientist

We drive advanced analytics and machine learning solutions to optimize pricing, enhance customer experiences, and power data-driven decision- making. Our projects span hotels and flights, fueling dynamic pricing and maximizing profitability. Key Contributions & Achievements* Dynamic Pricing Rollouts Built and deployed proprietary models for hotels, improving elasticity analysis, segment competitiveness, and boosting markups via feature engineering. Designed an alert system to track deployments, traffic patterns, and differences between theoretical and production models, mitigating misconfigurations in real time. Conversion & Regression Models Tackled imbalanced classification in conversion models, boosting accuracy by **5–8%** and driving a **€5M** business impact. Improved regression outputs by **3–5%** through strategic transformations and outlier reduction. Led a **3–5%** improvement in meta/non-meta performance, enabling rollouts on prime.com with a new architecture. Flight & Hotel Integrations Devised markup cross-check scripts for flights, ensuring deployment consistency. Developed ‘MapHolidays’ for holiday insights, enriching multiple models. Rolled out 9 new markups in August 2024, supporting dynamic, responsive pricing strategies. Core Responsibilities Conduct predictive analytics to understand behavior and anticipate user needs. Collaborate with cross-functional teams to align data science projects with business goals. Stay current with ML trends and communicate findings effectively. Technical Highlights Python, SQL, Spark, TensorFlow, scikit-learn, Bayesian optimization Elasticity analysis, segmentation, outlier management, distributed computing Why We Love What We Do By fusing data science and innovation, we revolutionize the travel experience for millions. We thrive in eDreams diverse, fast-paced environment, where impactful collaboration, continuous learning, and cutting-edge experimentation define our work
