Hello there, thank you for this opportunity to connect with you. If you need someone who has the technical and actual programming experience with blockchains and cryptocurrencies, please let me know. I am a multi-blockchain expert with Nxt/Ardor, Bitcoin, Ethereum, and Stellar, and also a full-stack Java architect/developer with over 16 years of experience. Please see my reviews for my related experience as well as my other actual projects here in Freelancer not appearing in my reviews:

I can configure and run Nxt/Ardor nodes, bitcoind (the Bitcoin daemon), Geth/Parity Ethereum clients, and Stellar services in Docker. I can also issue tokens and conduct ICOs with Nxt, Ethereum, and Stellar, and program smart contracts with Solidity. I can also program wallets and create APIs with blockchains.
Please see my profile for the rest of my portfolio and credentials. Thank you very much.
