● Maintains role based access control via the Ownable and tiered ownership design patterns.● Connects to ethereum node over JSON-RPC, and INFURA endpoints using Ethers.js general purpose library.● Implement ERC20 token standard Utilizes Open Zeppelin’s Solidity library of reusable and secure smart contracts.● Manages contract interaction and front end state via React.ts, in conjunction with Eth hooks, avoiding prop drilling and making use of reusable components.● Built with Hardhat’s toolchain, enabling better Typescript support, TDD development best practices and local contract deployment via Hardhat’s internal network.● Employs Test Driven Development for smart contract testing via Ethereum-Waffle.io framework, with fewer dependencies, clear syntax, and faster contract compilation● Deployed on Rinkeby public test network and via Surge.sh CDN, https://darkwingtokens.surge.sh/, https://darkwingtokens.surge.sh/● Expedites TDD via Hardhat-Deploy, an Open Source community plugin which uses an EVM snapshot, contract deployments are executed once, with each test

● A multi-signature wallet based on source code implemented by Stefan George of Consensys Mesh● MultiSig wallet Contract requiressome m-of-n quorum of approved private keys to approve a transaction before it is executed● Avoids Reentrancy vulnerability via check-effects-interactions pattern and using modifiers as guards.● Implements rate limits that internally trigger circuit breakers, halting external execution of specific contract functions

• Product developed under tech accelerator OS Labs (opensourcelabs.io).• VNO, a CLI which parsers, compiles, and bundles Vue components in a Deno runtime environment without the need for a configuration document.• Utilizes Oak, a Deno middleware framework, akin to Express in Node, to architect a RESTful API, separating functionality into modularized reusable components.• Utilizes Typescript to define the structure of Vue components, by enforcing constraints of static typing, giving developers documentation and a better debugging experience by moving some errors upstream from run time to compile time.• Implements server side rendering of Vue components by porting over tools originally developed for Node.js, allowing for the creation of Vue applications with improved search engine optimization in mind.• Designed and integrated a ‘live reload’ developer feature by triggering an automatic rebuild of the application upon the change of any files and utilizing a persistent websocket connection to reload the browser throughout development• Includes a modular SPA, vno.land, created with the vno build tool, demonstrating vno’s new SSR and live reloading capabilities.• Utilized Docker and AWS to deploy a containerized SPA, vno.land, created with vno, utilizing the portability and predictability of machine agnostic environments offered by containerization. => Currently transitioning to deno.deploy• Tested core functions using the built-in Deno test runner and standard testing libraries to ensure consistent behavior while adding new features.• Leverages Deno, a server side Typescript runtime built on V8 that prioritizes security, to implement asynchronous code using synchronous control structures and build components in a client’s directory in response to arguments passed by the client to the command line interface.

• Established a Node.js/Express server to efficiently handle HTTP/API requests to a myriad of endpoints by engaging the middleware design pattern, writing routers and controllers to modularize backend requests with a discernible chain of responsibility, enhancing code readability.• Leveraged a SQL database and its ACID compliance, specifically consistency, to execute queries and establish relationships between pertinent models.• Implemented OAuth to securely manage access to RESTful API, exchanging third party authorization tokens, and minimizing the work required for clients to access protected resources.• Utilized React component reusability and unidirectional data flow to build a single-page application with modularized and reusable components.• Utilized React Router to implement dynamic client-side routing of single page applications, minimize server calls and provide the client with a more seamless navigation experience.• Flashcard Memorization and Organization app developed for Open Source community.

• Combined Node.js, and Express to create a RESTful API capable of handling concurrent requests for data from frontend user interface components that drive client-side application state transitions as well as requests to information in the database• Utilized Webpack to bundle application files for production, allowing for code modularity and deployment efficiency, and configured a development proxy-server with hot-module-reloading to create a fluid development experience and debugging process. • Implemented a SQL database to execute queries and establish relationships between pertinent models allowing the updating of game state and have changes reflected for other players.• Combined React/Redux to manage state by connecting components to centralized store, avoid prop drilling, and clearly define actions in the app.
