Hello, I’ve carefully gone through your job posting. I am an expert Ethereum & Hyperledger Blockchain developer with more than 2 years experience. I am very much interested in taking your project with all of your requirements. I recently did a project very similar to your requirements , in which students were issued smart certificates on Blockchain , students were only able to only view the certificates , while the instructor had the authority to issue it or can revoke it. Do you only need a smart contract or you also need a front-end with it? Looking forward to hearing from you. Best Regards, Taha haq

Hi, This sounds like a project I might be genuinely interested in. It would be great if you could share more details about the scope of the project, so I can decide how good of a fit I would be. A little bit of background: I'm a solid backend engineer with blockchain experience an interests, familiar with smart contracts, Hyperledger and bunch of other blockchain technologies. I've build a crypto exchange from scratch in the past (see my profile), so I have a very good understanding of all the aspects. In any case, I'll be more than happy to discuss this project with you in more detail. Best, Vladislav

I've worked on Blockchain technologie for a year, and I'm curious to learn more and to have the opportunity to work on more real projects. I've been working on a POC that aims to make in practice the Zero Knowledge Proof Protocol. It was about giving proof for a bank that you do not have criminal records and so as to make the process of "Know Your Customer" more easier. I've also worked on Ethereum Blockchain Monitoring and on saving a copy of the Blockchain on Docker.
