I work in the standardized testing and assessment design space, with a primary focus on reasoning-driven content, item quality, and measurement integrity. My work involves creating and auditing test-representative questions across exams such as the GMAT, GRE, and SAT. This includes evaluating logical validity, controlling difficulty, detecting ambiguity, and identifying subtle flaws that affect assessment reliability. Across client engagements, I have created, edited, vetted, and quality-assessed 10,000+ assessment items for 30+ test-prep and evaluation-driven organizations. Since 2012, my professional focus has been exclusively on American test-prep and assessment content. My experience spans authoring, reviewing, and managing large-scale projects covering GMAT Focus, GRE, Digital SAT, LSAT, ACT, TOEFL, IELTS, and aptitude-based employee assessments. I have been involved in end-to-end workflows, including conceptual design, content development, author coordination, and LaTeX-based typesetting. Earlier in my career, I worked with Kaplan and later contributed to curriculum and course development initiatives, including GMAT Integrated Reasoning programs. These roles shaped my approach to structured reasoning, difficulty calibration, and evaluation-centric content design. I am particularly interested in work that involves reasoning evaluation, assessment design, content validity, and analytical quality control, areas that increasingly overlap with AI evaluation and model assessment.
