@danielonesimus
AI data annotator and rater improving model quality through precise evaluation, prompt feedback, and coding assessment.
What I'm looking for
I’m a final-year Electrical and Electronics Engineering student with hands-on experience in renewable energy and remote AI training. I’ve supported AI projects by evaluating AI-generated responses for accuracy, factuality, reasoning, and overall quality.
In my AI Annotator / AI Rater roles, I used detailed annotation guidelines to deliver consistent, high-quality outputs. I improved AI model performance through structured feedback, prompt evaluation, factuality review, and coding-related evaluation tasks.
Alongside AI work, I served as a Solar Technician on a 2.31 MWp utility-scale solar project, contributing to PV module installation, electrical wiring, equipment testing, commissioning, and preventive maintenance. I collaborated with engineers, project managers, and installation teams while maintaining strong safety and quality standards.
I’m now focused on remote opportunities in AI training, data annotation, quality assurance, and project coordination. I bring strong analytical thinking, attention to detail, fast learning, and clear technical documentation practices to build reliable, intelligent systems.
