I hold an MSc in Data Science with an undergraduate degree in Mechanical Engineering. I have been working extensively on the Microsoft Power Platform as a Data Scientist and Microsoft Power BI expert for over 5 years. While Power BI is relatively easy to learn, implementing well-designed and optimized dashboards based on complex data takes experience and skill. I've had the opportunity to successfully implement a range of Power BI based projects for listed companies across a broad range of sectors. I effectively process data from the source, through to the implementation of understandable and beautiful dashboards. I have worked hard on my ability to convey complex concepts in simple and elegant visualizations that all levels of the client team can understand and appreciate. Some of my key capabilities include: - Advanced Power BI dashboards - Data cleaning and consolidation (SQL, Azure Data Factory, R, Python) - Exploratory Data Analysis (EDA) - Advanced Power BI visualizations using embedded R and Python code I am experienced, detail orientated and thorough in all aspects. I pride myself on my ability to manage project timelines through clear communication and setting realistic expectations. I can happily provide a sample visualization of your data for a nominal fee before committing to a larger-scale project. I look forward to learning about your next Power BI project. Best, SeanR

I’m passionate about finding the hidden story in data. So whether that’s sifting through tonnes of datasets in Excel, querying databases in SQL or carrying out desk research to find the backstory and the best next step; that sounds like a challenge I am willing to take on. I have continued to grow my skills in my spare time, and I recently completed the Google Data Analytics Certificate on Coursera. I have always found the biological research space to be fascinating, which led me to studying a Masters of Science in Medical Microbiology at the University of Cape Town investigating the Stool Microbiota and Infant Wheezing. During my time at Injini (Africa’s first EdTech Incubator), I was pursuing a passion in innovative education, specifically the use of technology in education in Africa. There I provided research and project coordinator support to education technology initiatives across Africa, as the Data Insights Manager. For my next adventure, I plan to use my academic and professional background to add value to organisations by leveraging my strong problem-solving, research, and analytical skills to influence business decisions.R

You’ve got reports, spreadsheets, and numbers coming at you from every direction, but instead of clarity, you’re left with more questions: 1. Is your Amazon PPC campaign actually paying off, or are you bleeding ad spend? 2. Is your pricing strategy helping you grow—or leaving profit on the table? 3. Can that predictive model really guide decisions, or does it feel more like a gamble? 𝗜𝘁’𝘀 𝗻𝗼𝘁 𝘆𝗼𝘂—𝗶𝘁’𝘀 𝘁𝗵𝗲 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵.
