# Roland Wynter > Software Engineer Location: New York, New York, United States Profile: https://flows.cv/roland Experienced in building scalable full-stack applications with React, Node.js, GraphQL, and Typescript. Co-creator of PeachQE, an open-source query explorer built for Relay. Featured speaker at SingleSprout's Speaker Series: "A Deep Dive of React Hooks" Check out my Github: https://github.com/Rcwynter ## Work Experience ### Software Engineer @ Catch Jan 2021 – Jan 2021 | New York, New York, United States • Utilized a combination of Apollo, Zustand, and custom React Hooks to configure and maintain routing and state management along more than 30 variable routes for healthcare eligibility screenings to provide a smooth customer experience, secure data, and ensure CMS compliance. • Employed Studio 3T, Insomnia, and Apollo Devtools in conjunction with LogRocket to track data flow and app functionality. Bugs were made known via automated Sentry alerts, QA personnel, or user-reported issues. • Developed a cohesive and seamless cross-platform experience between web, ios, and android, while maintaining all front-end code in a monolithic React Native codebase. • Utilized Apollo and Apollo Hooks to query GraphQL servers in order optimize front-end performance and improve DX. • Collaborated closely with the Design team via Notion, Slack, and Figma to implement updated UI designs. • Improved DX by routinely updating coding standards and practices while also contributing to the design of a scalable front-end architecture. • Utilized Agile Scrum development to set sprint goals, product benchmarks and delegate tasks to individual team members. • Maintained platform’s Plaid link to connect and persist users’ connections to their bank accounts, enabling secure transactions with Catch’s financial tools. ### Full Stack Engineer @ PeachQE (Open Source) Jan 2021 – Jan 2021 • Built a GraphQL developer tool for visualizing and analyzing GraphQL queries in a Relay environment to allow developers to compare multiple queries, explore custom generated schemas, save query results, and analyze Relay’s advanced caching. • Deployed a Node.js server (powered by Electron) to build a multi-platform desktop application utilizing IPC communication protocol to run all processes client-side and reinforce data protection. • Utilized React and React Hooks to construct a Relay environment enabling developers to lazy load queries at request time, or optimize Relay’s performance by loading queries at build time. • Custom-configured Webpack with babel-loader to transpile Javascript E6+ and static code to bundle files and dependencies, minimizing file size to optimize load and render times as well as leverage proxy-server configuration for hot module reloading. • Utilized React-bootstrap component library to rapidly construct an intuitive UI for a seamless user experience. • Designed, built, and deployed landing page. • Product developed under tech accelerator OS Labs (opensourcelabs.io). ### SUD | Recovery Tracker @ Open Source Jan 2021 – Jan 2021 • Configured back-end to notify medical professionals/loved ones via Twilio of alarming shifts in mental health reflected in user-inputted data. • Implemented SQL database to efficiently store safely encrypted and ACID-compliant session and authentication data. • Employed Express to implement CRUD server controllers to utilize the scalable and event-driven non-blocking I/O of Node.js. • Designed and built front-end using React and React Router to dynamically populate SPA with personal health data. ### TaskIt @ Open Source Jan 2021 – Jan 2021 • Implemented React Router to boost performance while dynamically re-rendering a single-page application and populate rendered components with persistent data constructed from user interaction. • Used noSQL (MongoDB) database to maintain horizontal scalability and store loosely structured data for rapid retrieval by the frontend to populate the application with user-specific content. • Established a server with Express to maintain efficient performance and modularized middleware functionality while responding to high volumes of concurrent read/write requests to many HTTP/API endpoints, allowing the frontend and users to post and retrieve authorized information from the database seamlessly. ### Teem @ Open Source Jan 2021 – Jan 2021 • Utilized​ BCrypt native salt round method to make the application resistant to brute-force attacks and enhancing application’s user data protection. • Deployed noSQL (MongoDB) database to handle high volume of requests and rapidly retrieve/log data, optimizing manipulation of real-time data streams on the front-end of the application while allowing for horizontal scalability as user needs for data persistence increased. ## Education ### Bachelor's degree Sarah Lawrence College ## Contact & Social - LinkedIn: https://linkedin.com/in/roland-wynter --- Source: https://flows.cv/roland JSON Resume: https://flows.cv/roland/resume.json Last updated: 2026-03-29
