Tim Sutton

Director

Tim started his career by working in Nature Conservation in South Africa. Some years later, around 1998, an opening in the newly formed GIS group in the organisation where he worked presented an opportunity to combine his love of the environment with his enthusiasm for computers. What followed quickly became a deep dive into GIS (including obtaining a Master's Degree in GIS and Environmental Studies) and Open Source. He discovered Linux, also around 1998, and became an ardent fan of using and creating Open Source software. The announcement of the first release of QGIS in 2002 was another key milestone, with Tim quickly becoming deeply involved in the development of QGIS, as well as helping to build the community platforms and governance structures around the project. Formerly the QGIS.org Board Chair, Tim was awarded perpetual Honorary QGIS PSC Member status in 2018 and continues to play an active role in many aspects of the QGIS project. Tim is also engaged in the broader Open Source GIS ecosystem, including having the honour of being an OSGEO Charter Member and promoting the wide array of world-changing Open Source GIS tools provided under the OSGEO umbrella (and beyond) to pretty much anyone who will listen.

Recognising the need for professional services around the Open Source GIS ecosystem, Tim started his own company, Linfiniti, in 2008. Through a merger with Afrispatial, Tim co-founded Kartoza (https://kartoza.com) in 2014. The company helps Tim to achieve his personal vision of making spatial decision-making tools broadly available to everyone so that we can responsibly manage our precious earth and properly serve the societies that inhabit it. Today Tim's work at Kartoza focuses mainly on humanitarian, social upliftment, and environmental projects. Kartoza as a whole uses its skills in software development, consulting, training, and applied GIS to support customers in a broad range of disciplines from creating the building blocks of cloud-native GIS, smart farming, infrastructure management, energy planning and provision, national metadata initiatives, and many more interesting applications.

Today Tim lives on a smallholding in the Alentejo region of Portugal where he works remotely on his nice Linux PC collaborating with customers and his teammates over his amazing Starlink satellite internet connection.

Rudolf Jacobs

Software Developer

Rudolf comes from a humble upbringing in a small town called Meyerton. His parents raised him to be independent with a strong desire to learn and grow.

Rudolf has completed his degrees in BCom Chartered Accountancy in 2012 and Hons in Financial Accountancy in 2013.

Rudolf also completed his 3-year accounting articles in 2018 and passed his Professional Evaluation in that same year to become a registered Professional Accountant (SA) at SAIPA (The South African Institute for Professional Accountants).

During his accounting career, Rudolf continuously incorporated various programming tools to assist in his day-to-day responsibilities which stems from his philosophy to automate repetitive tasks (of which there are many in accounting). This enabled him to perform his duties at a much quicker pace than normal and granted him many successes.

After being inspired by his wife, who was also studying towards a new degree, Rudolf decided to formalise his programming skills and enrolled at UNISA for BSc Computer Science in 2019 and is expected to complete the degree in 2022 with only 9 modules remaining.

During this period, he was headhunted by Three I Developments (Pty) Ltd as their internal auditor in charge of implementing financial internal controls and started his own business AI Solutions (Pty) Ltd.

Whilst working for Three I, he was forced to use an internal system which was extremely slow and hard to use. After applying numerous updates and internal controls, this system was used to its full potential, but still remained cumbersome and slow to work with.

This inspired him to create an ERP system of his own called AI Construction.

In 2020, after vigorous research, Rudolf discovered Django, a Python based open source Web Development framework, which he immediately fell in love with because of its strong focus on rapid development and the DRY (don't repeat yourself) principle.

Using Django, Rudolf was quickly able to create his new website during the 2020’s Covid-19 hard lockdowns, which was used to replace Three I’s existing product. This website is still in use today, and has made the lives of his client much easier.

Given his success with AI Construction and nearing completion of his Computer Science degree, Rudolf decided to expand his horizons even further, and joined the Kartoza family.

Rudolf lives with his wife in Vanderbijlpark with their dream to one day work remotely from an island somewhere far away and beautiful.

His hobbies include cycling, gaming, walking the dog, 3D Printing and spending time with his family.
