    Obtaining a qualification in Economics had broadened my horizons to the world of modern business. The progression of my education had instilled princilpes about contemporary business and business management that has left a lasting impression on me and my career goals. Immediately after completing this qualification I began to delve into the world of economic modeling by creating a small project in which I was to provide a consulting service that would embrace art and the art market as an investment opportunity for individuals and businesses. At this point I came across the importance of gaining technological advantages by utilizing programs that could perform analysis using programs such as R and Python. My choice was to engage more with the Python programming language. Since then I have been increasingly exposed to economic issues that are affecting economies and businesses. I've found that I am most interested in the way that technology haas become an intergral part of streamlining business operations and the leading way to control business performance management. I would say that I am knowledgable of the different array of technologies available to the business fraternity and I would like to continue to engage with these technologies as I increasingly interact with players in teh market. My focus of late has been in the ecoinformatics and sustainability space where I have done research that has lead me to interests such as; smart manufacturing. I intend to gain the knowledge to be able to contribute to these markets and desire to keep learning within the fraternity.

    My journey into the world of technology began in South Africa, where I was born in 1973. Fascinated by computers from a very young age, I encountered my first computer-a Radofin Console-at just five years old, followed shortly by a Sinclair ZX81 with 16 MB RAM. These early experiences ignited a lifelong passion for technology and set the stage for my future endeavors. Computers and software design has been my lifelong task honing a great level of expertise. Communication is key to delivering a great solution on time every time. Practical remote work with full commitment and attention to detail leads to software you can enjoy and be sure of. Let me see how I can make this work for you. I'm looking forward to it.
