What I'm looking for

I'm seeking roles that combine clinical radiography with AI/data annotation or quality assurance, offering remote collaboration, opportunities to improve workflows, lead teams, and apply PACS/RIS expertise for measurable impact.

I am a Diagnostic Radiographer with hands-on experience operating MRI and CT equipment, assisting in fluoroscopic procedures, and ensuring patient comfort and safety while adhering to radiation protection protocols.

As a remote Freelancer / Data Annotator & Evaluator, I completed image, text, and audio annotation projects for AI training datasets, maintained 95%+ project ratings, adapted to various annotation platforms, and collaborated across time zones via Slack and Zoom.

As Head of Radiology I managed department operations, workflows, scheduling, equipment maintenance, and stakeholder communication, and I authored an article on radiographic image rejection; I maintain active HPCSA registration and up-to-date CPD compliance.
