Utilized the D3 library to construct a force-directed graph with a custom force to show directional relationships between tables in a relational database

Within a wrapper function, traversed the models in any given SQL database in order to parse raw SQL schema data into a readable format to be later utilized in the implementation of the data visualization

Applied unit testing in order to ensure the output of the data parser was correctly structured and included the complete set of information to be applied by the frontend

Migrated the smart contract and models to Hyperledger Fabric v1.4 in Typescript from Hyperledger Composer in anticipation of the deprecation of HLC coming later this year as well as to gain more control of the functionality and create a production ready solution

Created an OpenAPI yaml spec in order to have a centralized, detailed and readable version of the API

Designed and built an authenticated application in Node.js to host our API Documentation

Utilizing Loopback, migrated the Hyperledger Composer REST server in order to communicate with the Hyperledger Fabric v1.4 blockchain network

Leveraged React hooks and Typescript to develop a lightweight, modularized frontend application for users to interact with the blockchain network and view their reservations and dynamic tickets

Took advantage of Jest’s snapshot testing to unit test React Components in order to ensure consistency in the output of components

Wrote OpenWhisk actions (IBM Cloud Functions) using Python in order to verify the intercepted data received from the Tessitura client, interact with the blockchain, and proceed to return the necessary data from the blockchain transaction as well as additional information needed to store within the Tessitura database

Deployed the blockchain network to IBM Cloud in order to monitor and control channel members and and track the transactions submitted to the blockchain

Used React’s higher order component architecture and incorporated a tabbed section in order to create a container that dynamically displays data about events according to location

Used Redux state management to enforce a single source of truth and have the ability to retrieve event data from the store to be displayed in multiple instances
