The problem HARSH_PORTFOLIO solves

Portfolios are a great way to demonstrate the competencies you would list on a resume or talk about in an interview — they allow you to show and not just tell. During a job search, the portfolio showcases your work to potential employers. It presents evidence of your relevant skills and abilities.
Certain professions typically use portfolios to showcase their work. Artists, interior designers, cake decorators, graphic designers, writers, teachers, architects, and others in visual professions have been documenting their work in portfolios for years. Today, any professional in any industry can and should consider starting a portfolio.
