I'm a South African born SAP Specialist who got tired of the 9-5 grind and opted for a change of pace. My work experience is wrought with team collaboration and problem-solving. While my specialty may be SAP, I have extensive experience working with large data sets involving Master Data and Integration Tables. Having that experience also allowed me to expand into the Tableau Development world quite seamlessly. I've had great pleasure working with some of South Africa's largest corporations, as well as a number of larger, international clients. I truly appreciate the time I got to spend learning to work with people from different backgrounds and walks of life. The diversity has also taught me how to Project Manage in ever-changing environments. I am in possession of a strange super power: I am conflicted with both ADHD and perfectionism. I learn new skills fast and love drawing up specifications to document the information I've absorbed. But as I have a challenging attention span, I love to optimize and look for ways to make things better, automated and more efficient wherever possible. This super power takes effect whether I'm working on processes, visualizations or code. Here is a brief summary of the skills I've picked up along the way: - ABAP development - BASIS - Solution Manager ITSM - SAP Marketing - SAP Retail - SAP CRM - Tableau Dashboard Development - Mentoring / Training So as not to bore you to death, I've left out any office / admin related skills. Your eyes can thank me later. I'm sorry if that sounds flirty.
