Recently, I was checking one UX portfolio and realised that many senior UX designers still need to make up their portfolios. So here are a few suggestions from my side if you want to highlight your work:
Have your website - Even if you have a free version website, it's better to have a personal webpage with critical case studies than a Behance portfolio.
Clickable prototype- Instead of sharing screens or video recordings of your product, share a clickable prototype link.
Share critical case studies, including a well-defined problem, your role, tools and techniques used, process, challenges faced, final outcome, and learnings.
