Freelancer Overview

My experience in process analysis and quality leadership has been heavily centered on teaching, calibrating, and improving human decision-making at scale—an approach that closely mirrors how AI models are trained. I’ve worked extensively on translating complex guidelines into clear, actionable instructions, coaching teams to apply consistent logic when evaluating data, and continuously refining those guidelines based on observed errors and edge cases. This includes running calibration sessions, resolving ambiguity in interpretation, and ensuring high agreement rates across evaluators. In my current role as a Process Analyst, I focus on building systems that make learning and accuracy repeatable. I design feedback loops that help individuals understand not just what is correct, but why—improving reasoning quality over time. This teaching-oriented approach has allowed me to reduce inconsistency, strengthen critical thinking, and scale quality across large teams. I bring this same mindset to AI training: breaking down complexity, reinforcing correct patterns, and enabling reliable, high-quality outputs through structured learning.
