Used React Native to develop and maintain mobile app, with experience addressing both iOS- and Android-specific nuances.

Applied React Router (web app) and React Navigation (mobile app) to minimize loading time and promote seamless experience.

Built React-PDF-based NPM package to generate user-facing PDFs; employed a Next.js serverless function to permit PDF generation on both the frontend and the backend as needed.

Employed Jest, Testing Library, and Native Testing Library to launch and implement testing in both the web and mobile applications; served as lead on testing philosophy and execution.

Used GraphQL with Apollo Client to structure queries and mutations, with focus on creating living documentation and preventing data over-fetching to improve security and performance, including via intelligent use of Apollo’s caching system.

Implemented Material-UI-based design system to promote consistency in appearance across user interfaces and to create a library of reusable components to accelerate development and enhance developer experience.

Utilized Ruby on Rails to build queries and mutations and to structure and run SQL queries in a Postgres database.

Served as architect and tech lead on numerous projects; mentor junior developers via formal code reviews and informal pairing.

Introduced testing via Circle-CI to ensure functionality and performance of app prior to release and implement parallelization and test-splitting to accelerate Circle-CI job completion and thereby increase developer speed and productivity.

Employed Node.js to enable users to export fully functional application prototypes and save them locally.

Built Navbar React component and associated button and menu subcomponents using container pattern and React hooks and Context API to minimize prop-drilling while enabling buttons and menus to interact with data from other parts of application.

Implemented TypeScript to write and refactor React components and other functions to ensure consistency of data across a large and modularized codebase and to facilitate efficient error-checking and seamless work across a team of engineers.

Applied React-Redux to simplify state management and modified and modularized existing state and reducers to take into account varying state changes required by new functionality and to enhance readability and maintainability of codebase.

Employed Jest, Enzyme, and React Testing Library to write unit and integration tests for React components and Redux functions to ensure codebase integrity and to enable future refactoring and scalability without compromising functionality.

Used Travis-CI to automate testing prior to merging changes into organization’s central Github repository to ensure application integrity and functionality and to take advantage of Travis-CI’s close integration with Github’s VCS and workflow.

Integrated React DnD to enable users to dynamically build React component prototypes while preventing drag-and-drop to improper locations, with focus on intuitive user experience and potential for expansion to non-desktop media.

Utilized Material-UI to generate a modern user interface to enhance user experience and enable efficient component styling.
