Christian Ogboji

I am an AI trainer and customer support specialist with over three years of experience in data annotation, chatbot evaluation, and improving NLP model performance. I combine technical annotation skills with strong customer-facing experience to boost model precision and user satisfaction.

At TechMind Global Solutions I annotated large conversational datasets, trained models for natural language understanding, and collaborated with product and engineering teams to increase chatbot efficiency by 25%, while maintaining a 95% customer satisfaction rating. Previously, I supported over 200 users weekly at Skyline Connect, contributed feedback that improved chatbot accuracy by 18%, and worked across CRM platforms like Zendesk and HubSpot.

I hold a B.Sc. in Political Science and certifications in AI & Machine Learning, CRM, and remote collaboration. I deliver accurate, empathetic support in remote environments and document processes to improve workflows and training data quality.
