    I consider myself a passionate person about technology and innovation. I am quite curious and mathematics intrigued me since high school. Therefore, I enrolled in a Mathematics degree with a focus on Computer Science at the University of Bucharest. I think math can provide a pretty good answer to life's problems. It also helped me to evolve. It structured my thinking and expanded my imagination. As I became interested in Financial Mathematics and what "Quant" means, I followed a quantitative master degree (CEFIN) at Bucharest University of Economic Studies. Here, I learned how mathematics is applied in economics and finance and how to use statistical software to build models and manipulate data in order to draw proper conclusions. I expanded my knowledge throughout a master degree in Actuarial Techniques. I love volunteering. It taught me what it means to give back to the community and how to improve the lives of others. I learned these in ASMI, the students organization in Faculty of Mathematics and Computer Science.

    If you want to understand what's hidden behind your data, I'm your guy. In fact, if you're looking to get most out of your data, I might be the only one who can deliver what you're looking for. I know it's a bold claim, but let me explain. My name is Marius and I specialize in data analysis and data visualization. I do all of this in programming languages, such as Python, R and SQL, as well as, in visualization tools like Tableau, PowerBI, Microsoft Excel and Google Sheets. Plenty of Data Analysts say they're good at providing the best insights, but they make these mistakes: 1. They don't understand the data, therefore they cannot provide relevant visualizations for it 2. They just provide some visualizations put up together in a dashboard without actually understanding what it means 3. They think that the job stops after providing the dashboards On the other hand, I understand that the most important thing is to first understand the data. And I do this by: 1. Asking the right set of questions. So many analysts fail at this step because they don’t have a proven framework to go by. But I do – and I developed this in the 5 years working in the industry. 2. Selecting the relevant visualizations that’s going to provide you with the useful insights you need. Finally, I am not just a Data Analyst, I am also Storyteller. I don't provide just a dashboard; I also tell the STORY that hides behind it. So you can easily spot trends, insights and patterns in your data. Just like I did for this insurance company: “Marius is strong at sharing his opinion and weighing up different options before providing a recommendation.” When you work with me, we either go on a deep-dive call where I’ll ask you more about your business, the data, your expectations… Or, if the project is not super complex, I get straight to work. If you’re interested in gaining insights from a set of data, send me an invite today and I'll help you out.
