Summary
👤
Senior🎓
Top SchoolGonçalo Arsénio is a Senior Machine Learning Engineer based in Lisbon with eight years of experience building data-driven systems from research prototypes to production. He has progressed through roles in data science, data engineering, and ML engineering at companies like Feedzai, OutSystems and Mollie, developing a pragmatic view that ML is one part of large, complex systems. Gonçalo’s strength is bridging the gap between academic models and reliable production pipelines, informed by deep knowledge of the end-to-end data lifecycle. He prefers solving operational challenges—scalability, monitoring, and integration—alongside model development so solutions actually run in production. Trained in electrical and computer engineering at NOVA, he combines rigorous technical foundations with hands-on experience shipping ML features in payments and fintech contexts. Colleagues describe him as someone who translates experimental ideas into maintainable systems rather than just polished research artifacts.
