Your online portfolio is crucial for showcasing your work. 

Here's how to build one: 

1.  Choose a Platform: Use website builders (Squarespace, Wix), specialized sites (Behance, Dribbble), or GitHub for developers. 

2.  Curate Your Best Work: Prioritize quality, variety, and tailor projects to your audience. 

3.  Show, Don't Just Tell: Use high-quality visuals and case studies (problem, your role, process, solution, tools). Writers should link articles; developers, live demos. 

4.  Easy Navigation: Ensure a clean layout, clear categories, and prominent contact information. 

5.  Add a Personal Touch: Include an "About Me" page, professional headshot, and testimonials. 

6.  Optimize for SEO: Use keywords and descriptive titles. 

7.  Get Feedback & Update: Seek critiques and regularly update your portfolio with new projects. 

Building your portfolio is ongoing but vital for career success.
