The problem SkillUp solves

It provides the chance to present your skills by using a single, verifiable method. The NFT-based approach is trusted since it is minted and transferred by an algorithm. The NFTs are also soulbound that means fraudulent transfers and malpractices are not possible. Recruitment agencies can easily develop their own methods to verify the worth and value of applicants. This can evolve further than a certification tool to displaying other skills as well.
