I graduated from the Department of Mathematics and Computer Science at the University of Bucharest with a BSc in Mathematics and an MSc in Security and Applied Logic. I currently work as a Data Engineer specializing in the development of ETL data pipelines, and the design of big data jobs that employ engines such as Apache Spark. I previously worked as a full-stack PHP developer using the Symfony Framework with a focus on implementing security protocols.
