My vision for the future

I support the Sustainable Development Goals (SDG).

We must solve the most critical issues of our time within this generation. Doing anything else is a distraction.

About me

My formal background is in Chemical Engineering (North-West University) and Control Engineering (University of Pretoria). I have worked with multi-discipline teams in the power generation industry, designing water treatment plants and water & wastewater treatment plants. The first half of my career was dedicated to these design activities.The cloud has always fascinated me to increase your design tools' reach and scale your marketing potential. Thus, the second half of my career has gone into the detailed software engineering design for IoT alarm systems.For the next career phase, I will dedicate myself to solving specific automation and design problems to address the Sustainable Development Goals.We need to create a net zero energy world. The consequence of inaction is dust.

Latest projects

Pure Water Studio

The next generation of process engineering tools will require the following features:

  • An adaptive water treatment science calculation engine

  • Collaborative team design

  • Cloud storage

  • Open access to all stakeholders

  • P&ID visualisation

  • PFD visualisation

  • Isometrics visualisation

  • Bill of materials

  • Live equipment pricing

Following my progress as the MVP (Minimum Viable Product) for Pure Water Studio takes shape.


I revisited, among many other classical modelling methods, the use of Flowcharts, UML (Unified Modeling Language), ERD (Entity Relationship Diagram) and PFD (Process Flow Diagram) in software engineering and business development and have incorporated it into a new philosophy called Process Flow Diagramming Input-Out (PFDIO).Unlocking a pathway to greater efficiency, effectiveness, and user-friendliness, the PFDIO Canvas empowers you to visualise your processes, code, and systems with unparalleled intuition and seamlessness. Curious about the impact it can make on your projects? Dive in and witness the transformative difference.

In the grand evolution of software engineering, we stand on the shoulders of giants. As we stretch the boundaries of what's possible, humanity embraces a partnership with AI systems to amplify our craft. Amidst this ongoing progress, PFDIO stands out as a leader in innovation, promoting human creativity as its core value and building on postmodernist ideas. Offering a pristine diagramming canvas, developers, engineers, strategists, and students can unite to continue innovating and bringing their wildest ideas to life.
