What I'm looking for

I'm looking to help organizations adopt generative AI through practical workflow design, model evaluation, operational excellence, and customer-centric strategies that create measurable business value.

At Mercor, I evaluate and train large language models to improve reasoning, factual accuracy, instruction following, and conversational quality. I design and optimize prompts, review model outputs, and provide structured feedback aligned with AI safety standards.

I've built AI-assisted workflows and structured prompt libraries for customer success, executive communication, HR, business operations, marketing, research, and knowledge management. I also evaluate tools including ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, and Grok for practical business use.

My operations background includes leading daily finance, payroll, scheduling, billing, customer service, vendor coordination, and process improvement at Ridgemont Cleaners and NY Spot Cleaners. I’ve supported executive decision-making while improving workflow efficiency and service consistency.

I bring customer success and logistics experience grounded in consultative communication, reliable delivery, and strong client relationships. I believe AI should empower people—not replace them—and I focus on turning emerging technology into better organizational performance and customer experiences.
