South Africa

Message

At Molotov Cocktail, I analysed workflow inefficiencies and implemented structured process improvements that raised on-time delivery performance to 95%. I also developed Excel KPI dashboards to support performance monitoring and decision-making.

As an AI Annotator & Trainer at Micro1, I evaluate and annotate AI-generated outputs against structured guidelines and rubric-based criteria. I document failure modes, write rationales for ratings, and flag unclear guidelines to project teams.

Earlier, I supported continuous improvement as a Trainee Industrial Engineer at Mozweli (Pty) Ltd and improved production efficiency by 30% as a Production Planner at Deven Engineering. I’m an ECSA Candidate Engineering Technologist, with a Postgraduate Diploma in Industrial Engineering and a strong interest in applying emerging technology to engineering operations.
