Hi, I’m Stefanos Mantzos, a junior Business/Data Analyst based in Thessaloniki, Greece, currently completing a degree in Applied Informatics with a focus on Information Systems. I love turning complex data into clear visuals and practical insights, supported by hands-on work with data visualization, BPMN process modeling, and academic projects that bridge business needs with technical solutions. I’m motivated to bring analytical rigor, teamwork, and problem-solving to a junior analyst or project-oriented role. I’ve worked on data analysis and visualization using R and tidyverse (ggplot2), Power BI, and SQL; I’m comfortable in Agile environments and collaborating across cross-functional teams to deliver impactful results.
