Transforming data into growth through analytics and visualization
I’m Julien Ostrowsky, a Freelance Data Analyst and Power BI Specialist passionate about turning complex data into meaningful insights. My journey into data analysis began when I discovered the power of data visualization to drive decision-making and optimize performance. Over the years, I’ve honed my skills in Power BI, DAX, and data modeling, and earned multiple certifications, including the Microsoft PL-300.
I’ve had the privilege of working on various projects, helping businesses unlock the potential of their data through custom dashboards, automation, and insightful reporting. When I’m not deep into data, I enjoy running and competing in endurance events, including marathons and triathlons, which have taught me discipline, resilience, and the importance of a well-executed plan—qualities that I bring into my professional work.
In my free time, I also enjoy staying active through fitness and connecting with others in the data community to share ideas and learn about the latest trends in analytics.
