# Wilton Lee > Software Engineer Location: San Francisco Bay Area, United States Profile: https://flows.cv/wilton Software Engineer and open-source contributor experienced in developing full-stack applications (React, Redux, Node, Express, SQL, NoSQL). Currently working on Reactime, an open-source React time-travel debugging tool nominated at the React Open Source Awards 2020. Recently gave a public talk on Caching in the Jeeny & Bractlet’s Software Engineering Speaker Series! Check out my Github: https://github.com/wiltonlee948 Tech Stack: JavaScript, TypeScript, React, Redux, Node.js, Express.js, RESTful API, SQL, NoSQL, HTML/CSS, Git, Github, Docker, Travis CI, TDD (Jest, React Testing Library), Module Bundlers, AWS (EC2, S3, RDS, ECR, IAM, EB), Next.js, Redis, Tailwind, Bootstrap, tRPC, Prisma, ApexCharts.js ## Work Experience ### Software Engineer @ Reactime (Open Source) Jan 2022 – Present • Developed on Reactime, an open-source Chrome developer tool with over 1.8k Github stars that enables users to debug React applications by tracking and visualizing state changes. • Built and maintained a CI/CD pipeline utilizing Travis CI to automate testing and streamlining the deployment process to ensure the continuous delivery of high-quality software updates. • Implemented Docker containers to package Reactime and its dependencies, resulting in consistent and reliable deployments across development and production environments. • Integrated TypeScript into the software development process, leveraging static typing and custom type interfaces for tree data structures to improve code reliability and reduce runtime errors. • Traversed the React Fiber tree to identify components utilizing the useContext hook, and recorded snapshots of Context state changes to allow users to view which components were subscribed to the Context state. • Created a single page application using tRPC for type-safe network requests, NextJS for server-side rendering, and Prisma for data modeling and database management, resulting in a smoother developer experience. • Resolved 80% of open Github issues, actively contributing to the tracking and resolution of bugs such as black screen and maximum call stack errors to enhance user experience. • Contributed to the refactoring of the Reactime codebase, by working with a team of developers through a comprehensive code review and testing process to design a maintainable code architecture, reducing build times by 12% and drastically reducing code orientation time. • Employed Test-Driven Development (TDD) principles by using Jest testing framework and React Testing Library to ensure the quality and reliability of the application, writing and running automated tests covering a wide range of functionalities, from tree constructors to ensuring proper element rendering on the page. • Product developed under tech accelerator OS Labs (opensourcelabs.io) ### Software Engineer | Poller Bear | Polling App @ Open Source Jan 2022 – Jan 2023 • Architected a scalable and modular Node.js/Express backend server, utilizing middleware, routers and controllers to efficiently handle HTTP requests and facilitate asynchronous data flow between client and server, resulting in real-time updates of voting results for users. • Utilized React and its virtual DOM to optimize updates and improve rendering performance in a polling application, resulting in faster and smoother user experiences. • Implemented a PostgreSQL database to store and manage polling data, leveraging its ACID compliance to ensure data integrity and robust concurrency support to handle high levels of concurrent access and updates. ### Software Engineer | Stocklytics | Stock Tracker @ Open Source Jan 2022 – Jan 2023 • Leveraged Context API to improve the modularity of the codebase by providing a centralized way to manage state in the application, reducing prop drilling and resulting in a more efficient and readable codebase. • Incorporated Apex Charts library to generate intuitive and informative area graphs that effectively communicated key stock trends to users. • Deployed a NoSQL database to improve scalability and allow users to quickly retrieve their favorite stocks. ## Education ### Bachelor of Arts - BA UC San Diego ## Contact & Social - LinkedIn: https://linkedin.com/in/wiltonlee948 --- Source: https://flows.cv/wilton JSON Resume: https://flows.cv/wilton/resume.json Last updated: 2026-03-20
