Senior Product Designer to Improve My UX Portfolio Case Study (Figma)

I'm a recent design graduate and an international student in the U.S., currently preparing my portfolio. I'm looking for a highly experienced Senior Product Designer or Senior UX Researcher to help me refine one of my UX case studies to a professional, interview-ready standard. My goal is to bring this project closer to the quality expected by top product companies such as Google, Meta, or Apple. This is NOT a simple portfolio review. I'm looking for someone willing to work collaboratively and challenge my thinking. I want detailed, actionable feedback on my research process, storytelling, information architecture, UX decisions, interaction design, and overall presentation. I'm specifically looking for hands-on collaboration, including Figma comments, annotations, live edits, and concrete revision suggestions—not just high-level verbal feedback. Please include your portfolio website, LinkedIn profile (if available), and a brief introduction to your background. Preference will be given to candidates with strong experience in Product Design or UX Research, or with a proven track record of helping candidates successfully improve their portfolios. The budget is flexible and negotiable based on your experience and the level of support you provide. This project contains confidential work and cannot be shared publicly. By accepting this project, you agree not to disclose, reuse, publish, or include any part of the project in your own portfolio, presentations, or any public materials without my written permission.
