    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 stumbled into the addictive world of Tableau Dashboard Development at the end of 2016, but have been driven by OCD (or CDO, for alphabetical accuracy) tendencies since birth. This results in a love for taking raw information and fitting it into patterns and structures that tell a pretty good story. I also suffer from incurable boredom and insufferable impatience, so instead of waiting for others to help me do something, I'd rather look it up and figure it out myself. So truthfully no, I wouldn't make a very good delegator. I have an insatiable desire to do everything myself, because I feel as though I need to see the big picture. I may also have control issues… I learn best by doing something hands-on and my years of experience in the industry is the direct result of having taught myself the tools and knowledge necessary to succeed. Throughout my years in the corporate environment, I've also had clients request dashboards in Power BI and Google Looker Studio. I love learning, so I'm always willing to pick up a new skill if and when I need to. I've contracted to a number of corporate and international clients that include Distell, Implats, Big Chalk Analytics, Pipetto and Creative Channel Services, among many others. As such, I've worked with people from the USA, Australia, Germany, the UK, and of course, South Africa. I've also designed dashboards for ecommerce / retail, finance & cryptocurrency, green living / green energy, food & beverages, mining, farming / agriculture, education and healthcare industries. In some cases, I was even required to reshape the raw data and communicate that information to the relevant data teams in order to complete the necessary outputs. This has resulted in the successful delivery of over 50 projects within 7 years; most of which were made possible through my Upwork profile. Finally, I have frequent love affairs with languages (both lingual and computer-based), but in typical ADHD fashion, I tend to jump from one to another too quickly before mastering any. That's right, with me you get a two for one combo of OCD & ADHD! Right now, JavaScript and I have quite a good thing going.

    𝗜 𝗗𝗶𝗱𝗻’𝘁 𝗖𝗵𝗼𝗼𝘀𝗲 𝗣𝗼𝘄𝗲𝗿 𝗕𝗜 – 𝗣𝗼𝘄𝗲𝗿 𝗕𝗜 𝗖𝗵𝗼𝘀𝗲 𝗠𝗲 I stumbled into the world of Power BI consulting long before it became the buzzword it is today. Data storytelling, business intelligence, and the thrill of turning raw numbers into insightful, interactive dashboards—it was an instant match. Some might call it an obsession; I call it precision-driven problem-solving. I don’t just build dashboards—I craft narratives through data. Because at the end of the day, a dashboard is only as powerful as the story it tells. A well-designed report doesn’t just present numbers; it guides decision-makers toward smarter strategies, deeper insights, and faster actions. That’s what I deliver. I also have control issues—I don’t just want to build something and walk away. I need to understand your business, your goals, and how every metric fits into the bigger picture. That’s why I don’t just take requests—I ask the right questions to ensure my dashboards drive real, measurable impact.
