Summary
👤
Senior🎓
Top SchoolWilliam Jackson is a mining engineer-turned-entrepreneur who has run geophysical surveys and water borehole siting across Zimbabwe since 1991, combining field reconnaissance, EM and resistivity methods to locate groundwater. He rebuilt and modernized his own resistivity instruments, adapting legacy geophysics techniques with contemporary electronics and satellite imagery to improve success rates in challenging terrains. Owner of William Jackson Surveys, he has balanced commercial projects, teaching undergraduate physics, and community-focused school IT/network builds, showing versatility between hands-on field work and technical education. During the 1990s he was widely contracted across Matabeleland and beyond, and after setbacks in 2000–2002 pivoted to operating a gold stamp milling centre while rebuilding his hydrogeophysics practice. More recently he has contributed code to the well-known TiddlyWiki5 project, enhancing filter operators and action widgets, reflecting a pragmatic mix of field engineering and practical software development. Based in Zimbabwe, he brings decades of local geological knowledge, instrument design experience, and a habit of adapting tools and skills to meet scarce-resource challenges.
