About
I’m a Data and Analytics Engineer with a focus on Big Data and a passion for turning data into actionable insights. I recently pursued a Master of Engineering in Big Data and have worked across global teams including Revolut, BNY Mellon, State Street, Microsoft, ABB, Evidences Analytics, Avaus and Santander. My work spans AML analytics, data pipelines, data lakes, graph analytics, NLP projects and large-scale data migrations, always aiming to align technical solutions with business goals.
I’m proficient in Python and SQL, with hands-on experience in Spark, Hadoop, Databricks, Azure and GCP. I enjoy solving complex data problems in Agile environments and I’m exploring Generative AI and RAG-enabled data workflows to enhance decision-making, governance and security.
