What I'm looking for

I seek a role where I can apply AI data annotation and evaluation skills within a collaborative, quality-driven team focused on improving model accuracy and reducing bias.

I am a detail-oriented computer scientist with hands-on experience in data evaluation, content moderation, and AI productivity tools. I have contributed to AI model training and quality assurance through fact-checking, misinformation detection, and precise data labeling.

I bring technical troubleshooting, process optimization, and project management experience from remote roles that required adherence to strict guidelines and high-quality outputs. I hold certifications in AWS Cloud Practitioner and ISC2 cybersecurity, and I apply machine learning concepts to improve model performance and reduce bias.

I am multilingual and excel at customer engagement, communication, and training guidance, eager to apply my skills to refine AI systems, enhance user experiences, and support scalable annotation workflows.
