Hi, there. How are you? Hope you are safe from covid. I am a full-stack blockchain developer with about 8 years of web development experience (laravel, nodejs, react, vue, angular, etc ), more than 5 years of mobile app development exp, and more than 2 years of strong blockchain exp. So far, I have developed many projects and have received favorable reviews from clients. if I say my previous work, I have developed many types of NFT marketplaces, swap, staking sites so far, and have been particularly involved in the development of smart contracts (include Blockchain backend). I believe that there is a client of mine who will work with me for a long term with a good relationship. I think you are that client. I can work full-time for more than 40 hrs a week, and the time zone can be set arbitrarily. I will do my best and provide great quality. Mobile apps (Android, IOS) are not a problem either. If you hire me, you can see my skills and you will work with me. I look forward to your reply. thank you so much.
