Summary
👤
Senior🎓
Top SchoolColin Andrew is an interdisciplinary engineer and entrepreneur with 16 years of professional experience and three decades working at the intersection of sensing technology, biomedical engineering, and real-world deployments. He founded and runs multiple ventures (Red Five Consulting, Essentric) while advising large industrial clients like Anglo American on sensing solutions, and holds longstanding honorary research and teaching roles at the University of Cape Town. Technically hands-on, he contributes to core open-source infrastructure—having fixed bugs and added features to the widely used Exim mail transport agent—reflecting an appetite for low-level, security-relevant engineering. With a PhD in Electrical and Biomedical Engineering and a background spanning academia, R&D at De Beers, and product ventures, he blends rigorous research, practical system integration, and commercialisation. Colleagues describe him as a pragmatic problem-solver who bridges lab-grade sensing methods with operational industrial systems in South Africa.
