Summary
👤
Senior🎓
Top SchoolDerek Hohls is a seasoned software engineer with 12+ years focused on sensor-driven environmental information systems, satellite imagery, and scientific workflows. He blends deep domain experience in water and air quality, forestry and marine monitoring with hands-on skills in database design (MySQL, PostgreSQL/PostGIS), devops (Docker), and full-stack programming across Python/Django, Fortran, Delphi and web technologies. Much of his career was spent at CSIR building decision-support tools that integrate in-situ and remote observations, and he continued that work at Geo Intelligence Corp before moving to independent consulting. Derek’s strengths include turning complex geospatial and sensor datasets into auditable, production-ready APIs and pipelines. He is comfortable across legacy scientific codebases and modern containerized deployments, and often bridges the gap between researchers and operational systems. Based in Gauteng, South Africa, he brings a pragmatic engineering approach informed by decades of water-quality and environmental monitoring practice.
