We are rebuilding the platform to support TGN’s next stage of growth, including expansion into the United States. A stronger and more intuitive front end is therefore critical it directly affects how easily users can register, discover opportunities, understand Offers and move through the platform. The contribution of an experienced volunteer could have a very visible impact because this is not a speculative project. It is an existing social-impact product with real users, real workflows and a live roadmap.
