Hello, I'm
Miguel Marinho
Senior AI Engineer & Data Scientist at Nokia
Senior AI Engineer driven by curiosity & real-world impact, building AI systems that turn complex ideas into practical, production-ready products. More about Miguel Marinho.
About me
I began my journey in the ever so small country of Luxembourg — European School, three languages, a multilingual upbringing — and moved to Portugal at 17 to pursue my studies. Since then, I've built my lane at the intersection of AI engineering, data science, and data engineering, turning messy business problems into production systems on Azure Databricks. Currently a Senior AI Engineer at Nokia, focused on turning complex business requests into production AI agents: knowledge agents that reason over internal documents, data agents that act on live databases, and reporting agents that transform plain language into governed business outputs.
I've always been a guy of odd interests. When I was younger I was really passionate about martial arts and computers. This inherently led me to building my own computer and joining my first boxing gym.
Fast forward some years and I box on an amateur level with aspirations of becoming national champion in 2027, and also ... play chess. Chess is my go-to chill activity. It's kind of like the calm, strategic counterpoint to the adrenaline rush of boxing. Some people find it odd, I find it complementary.
Something that also defines me is my passion for meeting new & different people. Probably because I was born in Luxembourg and always surrounded by different cultures and languages. Regardless, this type of passion has made me pretty open-minded and really incited my passion for travelling.

My experience
Leading production AI agent development on Azure Databricks, translating ambiguous business needs into governed agentic systems that people can use in daily operations. Specialized in building agents that reason over enterprise knowledge, retrieve and cite internal documents, query live databases from plain-English requests, and turn business intent into deterministic, shareable reports. Owns the full path from architecture and orchestration to evaluation, deployment, feedback loops, and continuous improvement across production environments.

Data Scientist / Data Engineer
NOKIA
Translated supply-chain reporting needs into scalable Spark SQL and PySpark data products used for operational and executive decision-making. Designed critical KPI milestones, strengthened dashboard data models, scaled a cross-server table comparator for UAT mismatch diagnostics, integrated delivery with Azure DevOps CI/CD, and built a stacked Azure ML model to improve on-time delivery prediction.
Data Science Trainee in Rotational Program
NOKIA
Rotated across Supply Chain Analytics, Process Mining, Data Semantics, and Financial Planning, building a broad foundation in data engineering, ML, process automation, SAP reporting, Celonis, and cloud migration. Migrated pipelines to Azure SQL DB with Azure Data Factory, led SQL-based UAT validation, automated Celonis audit-log ingestion, modeled star schemas, shipped dashboards, and optimized SAP reporting on a centralized data platform.
