Experience
Crypto Token Design and Ethereum Blockchain Smart Contract Development
Developed the web front end using JavaScript, Vue.js, and React to tokenize assets, confirm and prove authenticity, and track with a blockchain-based, tamper-proof audit trail.
Set up Crypto Trading Exchange on AWS
Tested API Interfaces and access from React-based web interface.
Crypto Token Sale Platform using Chainlink VRF
Additionally, I created algorithms specifically for blockchain use to execute in constant time while still allowing unlimited scalability, despite limited gas.
