Crypto Token Design and Ethereum Blockchain Smart Contract Development

Developed a custom Crypto Token based on Ethereum Blockchain.

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

Set up and deployed the Crypto Token Exchange on AWS EC2 using Docker container., leveraging AWS Fargate and Elastic Container Service (ECS).

Tested API Interfaces and access from React-based web interface.

Crypto Token Sale Platform using Chainlink VRF
I developed smart contracts in Solidity for a new crypto token sale. and for a lottery using Chainlink VRF.

Additionally, I created algorithms specifically for blockchain use to execute in constant time while still allowing unlimited scalability, despite limited gas.
