I'm Sarah Kelley, founder and principal consultant at Quadacity LLC. I'm completing my Master's in Industrial-Organizational Psychology (expected May 2026) at University of Phoenix, with a focus on evidence-based approaches to workforce development, organizational change (including ADKAR), and human-centered AI applications. Through Quadacity, I help small to mid-sized businesses adopt AI practically—creating high-quality human feedback, preference rankings, prompt optimization, and evaluations to improve large language models—while also supporting business strategy, HR processes, culture building, and critical thinking via Devil's Advocate consulting to uncover blind spots and pressure-test ideas. My approach is straightforward: no hype, just targeted, measurable results. I draw from I-O principles to bridge people, processes, and emerging tech. Open to connecting on AI upskilling, change initiatives, or honest feedback on your plans. Let's chat if you're a growing organization ready for practical support: www.quadacityllc.com
