Hello. I am a Solidity developer and have launched some ICOs/tokens before. I can show you some demos if you are interested. We can develop contracts and add unit tests, ... and deploy on ETH test nets and then move them to main ETH network after tests. Thanks, Vahid

Hello ! At this moment I am working for my project, I called it admigo. This is an admin panel on golang, postgresql, vue.js and bulma css framework. This admin panel has feature like a shop. Clients can buy something via smart contract, once they bought something, they can't buy more items until they confirm or cancel theirs purchasing. If they canceled then ethers return back to their wallet. I can't show it for You right now, because all code in my local computer, but if you are interested I will upload on a server and you could see.

Dear client. I am excited to find a suitable job with my skills. I have great interest in your job since I have extensive skills and experience in blockchain technologies and its applications. I specialized cryptography and have a master's degree of computer science & technology. Have studied from 5 years about blockchain tech - modern top trend. It appeals most of people and me as well because it can allow us to be free from governance and politic obstacles to match people and make contracts and financial movements. I had great interest in Ethereum, because it is not only a crypto currency but also a smart intermediary that people remove much of paper work and politic limit & governance. They can credit others via blockchain and strong cryptography. So I have studied deeply about ethereum and blockchain development. I have developed social matching websites leveraging blockchain technology. Also developed smart contracts in Solidity for voting, sports betting web applications, financial exchange applications. I am confident in your job and can guess what your looking for in this job. I hope to get a solid opportunity with you on this job. I am looking forward hearing from you. Regards.

I can also deploy the smart contracts to the Ethereum mainnet, so I can handle the complete lifecycle of the contracts. Also, I have experience working with Linux and system administration.
