Lisbon, Portugal
Summary
👤
Senior🎓
Top SchoolJavier Adell is a Machine Learning Engineer specializing in reinforcement learning with nine years of experience building and deploying production-grade ML systems across startups and scale-ups. He has led data teams and designed cloud-native, Kubernetes-backed infrastructures that integrate ClickHouse, S3, Dagster, dbt and Postgres to power analytics, forecasting and microservices. At Glovo he owned courier forecasting pipelines combining ML, Bayesian models and linear programming; more recently he directs RL efforts at SIXT. Comfortable across the full data stack—Python-first modelling, SQL ecosystems, CI/CD and orchestration tools—he balances research rigor (PNAS-published work on satellite imagery) with pragmatic engineering practices like automated testing and observability. Based in Lisbon, he brings a hybrid background in political science and data science, which helps him frame technical solutions around real-world decision-making and product impact.
