# Justin J Davies > Senior Software Engineer | React | Typescript | JavaScript | Ruby on Rails Location: Glen Allen, Virginia, United States Profile: https://flows.cv/justinjdavies I’m a software engineer with over 4 years of experience who thrives in fast-paced environments, always focused on solving problems in ways that make sense for both the codebase and the team. I care about writing clean, scalable code and collaborating to build impactful products. My experience spans React, TypeScript, Ruby on Rails, and recently some work with Java both professionally and in personal projects. At Cotality, I led efforts modernizing lender UIs and improving reliability, while at Roostify, I helped transform legacy Rails APIs and built reusable React components. I’ve also worked with Docker, AWS Kubernetes, and I’m currently exploring Generative AI through a certificate program with Johns Hopkins. In my personal projects, I’ve shifted from using Go to building an API in Java to gain more hands-on experience with the language. Outside of work, I enjoy golf, family time, and learning new technologies. Always open to new connections and opportunities! ## Work Experience ### Senior Software Engineer @ CoreLogic Jan 2023 – Present - Led technical implementation for a lender UI redesign, completing 57 of 240 tickets as top team contributor. - Built responsive React and TypeScript components integrated with modular APIs. - Maintained security with JWT auth, input validation, and regular dependency updates. - Monitored AWS EKS pods, checked logs, and performed live debugging for production stability. - Developed automated Playwright tests to improve reliability. - Identified design issues early, improving project timelines. ### Software Engineer @ Roostify Jan 2021 – Jan 2023 | Remote - Translated Figma designs into production-ready web applications using React and TypeScript. - Built scalable features in a React monorepo using Material UI. - Contributed to migrating monolithic Rails APIs into modular services with JWT auth. - Updated dependencies to mitigate security risks. - Developed borrower and lender flows, aiding the company’s acquisition by CoreLogic. - Mentored junior engineers and contributed to Agile processes. ### MLH Fellow @ Major League Hacking Jan 2021 – Jan 2021 Worked on a Learning Management System with my pod for Tour of Duty through Major League Hacking ### Web Development Student @ Flatiron School Jan 2020 – Jan 2021 | Austin, Texas, United States Below are the projects I completed: _weBudget_ - provides tools to effectively allocate your funds - + Developed a React application using Redux, contributing to a user-friendly financial allocation tool. + Implemented JSON web token authentication using Rails API, ensuring secure user access. + Built controlled forms using JSX, enhancing the application's usability. _Thank You For Tia_ - displayed a menu for a fictional food truck - + Developed a software application integrating a Rails API with a user-friendly interface using Vanilla JavaScript. + Employed fetch requests for seamless backend communication, efficiently retrieving and managing data. + Organized data by creating and storing objects in JavaScript classes, optimizing scalability. + Utilized Vanilla JavaScript to manipulate the DOM, ensuring a smooth and interactive user experience. _Mans Best Friend Fitness_ - offers a pet owner the opportunity to journal and keep track of their pets health - + Developed a Ruby on Rails project adhering to the MVC pattern. + Integrated OmniAuth for seamless Facebook sign-in functionality. + Implemented OmniAuth so users can sign in with Facebook  + Implemented authentication using the Devise gem for enhanced security. ### Veterinary Technician @ ZippiVet Jan 2019 – Jan 2020 | Austin, Texas, United States + Improved daily operations by enhancing communication, ensuring technicians clocked out on time. + Trained and mentored 4 vet technicians on animal care procedures, facility policies, and industry best practices. ### Veterinary Technician @ Banfield Pet Hospital Jan 2017 – Jan 2019 | Austin, Texas Metropolitan Area + Trained new employees on animal care and work expectations + Advocated for communication and team work ## Education ### Software Engineering in Computer Software Engineering Flatiron School Jan 2020 – Jan 2020 ## Contact & Social - LinkedIn: https://linkedin.com/in/justin-j-davies - Website: https://justindaviesdev.vercel.app - GitHub: https://github.com/Therealjustindude --- Source: https://flows.cv/justinjdavies JSON Resume: https://flows.cv/justinjdavies/resume.json Last updated: 2026-03-22
