Hi, not sure how difficult it will be to make this feature but if possible then having such feature will definitely help many to gain more visitors & users. Since Jobs & business posting is part of osclass, having a plugin that will allow users to create resume and portfolio with some inbuilt template, which can be saved, edited anytime, shared with others, will be very helpful for users as well as site owner. As site owner can charge user a small annual fee to use that feature. User can directly attach downloadable resume link when they apply new job.

Problem is very small and limited market for this tyoe of classifieds.
Not a problem to create, but someone needs to cover development.
