IOHK (Cardano cryptocurrency) is developing a new privacy-centric, programmable blockchain and network called Midnight. Midnight is leveraging zero-knowledge proofs and a proprietary smart contract programming language to deliver a private, smart contract enabled, decentralized blockchain network. Midnight includes a suite of dApp development tools, SDKs, and an official light wallet for the browser to support the native token. Achievements Lead the front end development of the midnight-client-sdk. This SDK allows other front end developers to build dApp UI’s in the browser. The SDK is installed like any other Javascript dependency and exposes an API which facilitates communication with a node on the Midnight network to deploy or join smart contracts from the browser. Lead the front end development of the official Midnight Light Wallet. The wallet is offered as a chrome extension to support the blockchain’s native currency and seamlessly connects with the midnight-client-sdk to facilitate the signing of transactions and provides a container in the browser to execute smart contract code. - TypeScript, React, Redux, GraphQL https://midnight.network/ ### Co-Founder @ Meditate AI Jan 2020 – Jan 2021 | San Francisco, California, United States Meditate AI provides medical data sourcing, annotation services, and annotation software for companies in the medical AI space.

I worked on Daedalus, a full node desktop wallet and the official wallet for Cardano. Daedalus is an open source, decentralized application that provides a highly secure and globally accessible environment for network participants. Core features include the creation and restoration of HD wallets, paper wallets, and integrations with the most popular hardware wallets. Daedalus facilitates secure transactions and serves as the access point for Cardano’s formally verified proof of stake protocol. Achievements: Designed and implemented a themeing engine for Daedalus which saved our team many developer & designer hours. Using a simple pallet of colors as input, the themeing engine generates a new theme which covers the entire UI without need for manual implementation. Using the engine, themes can rapidly be tested and vetted on the UI instead of requiring a designer to manually create one and engineers to implement it. Built the staking UI which allows user to delegate ADA to one or many of the network’s stake pools to earn passive rewards on their staked funds. Lead the development and maintenance of an open-source front end component library called react-polymorph. React-polymorph is used throughout Daedalus where heavily tested functionality is required. React-polymorph is also used in a handful of other products within the Cardano ecosystem and is available for use to third party developers on Github and NPM. - Electron, React, MobX iohk.io | daedaluswallet.io | github.com/input-output-hk/daedalus | github.com/input-output-hk/react-polymorph ### Full Stack Engineer @ Esprezzo Jan 2017 – Jan 2018 | San Francisco, California Esprezzo allows developers with diverse technical backgrounds to create blockchain enabled web & mobile apps.
