About Korey Wang Tianru Portfolio
Personal product portfolio by Korey Wang Tianru: Fitness OS (built from serving 40+ gym members), TEM4 workbench (53 to 69), and open-source resume-claim-guard.
Korey Wang Tianru Portfolio (https://korey2028.tech) is a custom-built personal product manager and builder showcase based in Beijing, Class of 2027. Instead of generic templates or unverified claims, the site documents practical software workbenches built directly from real operational problems across fitness coaching, language exam preparation, tabletop role-playing game hosting, and technical campus recruiting.
The flagship case study, Fitness OS, is an interactive coaching workflow workbench created from personally serving 40+ gym members on the training floor. It unifies session planning, member progress tracking, and client check-ins, accompanied by a live interactive web demo. The second featured project is a dedicated TEM4 exam preparation workbench that helped improve the author's official test score from 53 to 69 through structured practice loops and error analysis. Additional projects include a DM rehearsal handbook for structured narrative hosting, a job-search operations console, and resume-claim-guard, an open-source MIT-licensed AI agent skill designed to enforce strict factual boundaries in resume writing and interview preparation. Each project page clearly outlines the problem statement, product tradeoffs, interactive deliverables, and explicit claim boundaries.
