I am a technologist and engineer by trade, with an appreciation for science. I have an affinity for people and what matters to them, with a need to work in a trusting, open and collaborative environment. I am intrinsically motivated and have solid analytical and mentoring skills. I value integrity. I enjoy solving problems while finding a balance between what the business or customer needs vs. implementing a sustainable solution. I have managed several teams and successfully delivered projects over more than 20 years using pragmatic agile principles. I have a passion for process and system automation, and software quality. I have significant experience in these areas and drive this with every team that I've been involved with or lead. My technical domain knowledge entails the design and implementation of distributed, highly concurrent systems as applied in the fields of social media, location-based services, value-added services, general system integration and e-commerce. I know a variety of programming languages and modern technologies. Besides software architecture, I'm also well versed in business analysis and business process modelling. I have contributed to start-ups three times, lived through one major sale of shares and one acquisition, while being on the due diligence team on both occasions. Besides my experience in software development, operations and product management, I have a passion for data analytics, as supported by my qualifications in digital signal processing and machine learning. I believe it is important to engage with the ICT community on a regular basis and for that reason I have participated by means of presentations, interviews and articles. Living a balanced life is vital to me. I value spending time with friends and family. I compete in mountain biking and running. My love for music allows me to escape from work in order to revitalise. I play the piano, among other instruments, and enjoy on-stage performances for a cappella singing.
