Jennifer Brock

I’m a versatile digital professional with a strong background in AI model training, data annotation, and virtual administration. I evaluate complex data, engineer precise prompts, and manage multifaceted digital operations with a detail-first mindset.

In my AI Data Trainer & Evaluator work, I engineered complex, targeted prompts to test and improve generative AI models across various domains. I evaluate responses for accuracy, safety, helpfulness, and logical consistency using established RLHF guidelines, and I conduct rigorous fact checking to identify hallucinations or bias.

I also assess multi-turn conversational AI for logical flow, tone consistency, and contextual accuracy while navigating complex, ambiguous guidelines for quality ratings. I provide detailed, constructive feedback on model outputs and maintain strict adherence to project-specific formatting and quality standards while consistently meeting high-volume quotas.

Alongside that, I’ve delivered comprehensive remote administrative support as a Freelance Virtual Assistant & Digital Operations Manager. I manage daily inbox triage, scheduling, customer inquiries, and data entry, and I lead end-to-end digital product launches—from formatting and proofreading to live publication and promotional marketing.
