Describe a course or training you completed that helped you

A couple of years ago, I decided to enrol in a comprehensive data visualisation course offered by a local tech academy in Manchester called 'DataFlow'. It was an intensive six-week programme that ran on Saturday mornings, which was perfect for my schedule as I was working full-time in marketing at the time. I had reached a point where I felt my reports were becoming stale, and I really wanted to find a way to make complex consumer data more accessible to my colleagues. Throughout the course, I was introduced to software like Tableau and Power BI, learning the intricacies of dashboard design and how to choose the right graphical representation for different datasets. We spent hours dissecting real-world case studies, which really helped ground the abstract theories in practical application. The instructor, a seasoned analyst named Sarah, was incredibly insightful, teaching us that the best visualisation is often the one that tells a clear, human-centric story rather than just showing raw numbers. Since completing the training, the impact on my professional life has been significant. I now spearhead the monthly analytics presentations for our board members, and the feedback has been overwhelmingly positive. Colleagues who previously glazed over during my presentations now actively engage with the data because it is presented with such clarity. It has definitely boosted my confidence when speaking in meetings, and I feel much more capable of driving strategic decisions through the insights I extract. I believe this course was a turning point for my career because it shifted my perspective from merely reporting data to actively using it to influence our company's direction.
