# Zerry Hogan > Founder of Democrasee.io | Platform Engineer at Elation Health Location: Austin, Texas, United States Profile: https://flows.cv/zerry A passionate Software Engineer with deep expertise in Javascript, TypeScript and React who loves to build scalable user interfaces that solve complex and/or interesting problems. I am part designer and part engineer. I work with stakeholders, engineers, designers and researchers to design and implement effective and beautiful user experiences for any given product. I have an aptitude for learning new technologies and I am always expanding my skill set. Specialties/Skills: - JavaScript (ES7, ES6, ES5) - TypeScript - CSS and Styled-Components - React JS - React Native - React Testing Library - Jest - GraphQL - Redux/Redux-Sagas/Reselect - REST APIs - Project Management - Unit Testing - User Experience - Leadership ## Work Experience ### Staff Platform Engineer @ Elation Health Jan 2022 – Present | Houston, Texas, United States - Built and maintained our internal React component library that was used by our app engineers to build our various applications - Built a platform agnostic testing library called Vital Testing Kit which had a declarative API that made it super easy for our QA Engineers and Frontend Engineers to write unit tests and E2E tests for our applications. This library increased the speed at which tests could be written, increased the quality of our test code and reduced our test flakiness by 300%. - Vital Testing Kit abstracted away the complexities of writing tests for dynamic UI's that contain complex components and UI interactions. It also forced our Application UI's to be accessible due to its design so by using Vital Testing Kit we also increased the accessibility of our applications - Vital Testing Kit was design in such a way that it could be used with any testing frame (such as Jest, Webdriver.IO and Cypress). This allowed for Testing Kits to be created once and re-used across all of our testing infrastructure. - "Reactified" several parts of our application and created a standard process for "Reactifying" that reduced risk and increased the speed at which applications could be "Reactified". "Reactfication" was the process in which we converted our 12 year old legacy jQuery code to Modern React. - Architected the initial version of an AI Support Chatbot that used a vector database indexed with our help documentation and used as context for ChatGPT. This chatbot helped reduced customer support requests and increased customer satisfaction. - Worked on our React Native mobile apps to help add features, built CI/CI infrastructure for deploying them and automated our release process. - Led weekly FrontEnd Guild's to help educate engineers and answer any questions/debug issues. ### Senior Software Engineer @ PayPal Jan 2021 – Jan 2022 - Build and manage PayPal's multi-cdn infrastructure at the edge to support PayPal's goal of all of their services/apps being 99.99% available. A multi-cdn approach reduces the likelihood that static assets will become unavailable in the event that a single CDN goes down - Build and manage PayPal's Multi-CDN user interface, api and cli to enable no-code static asset deployments for teams at PayPal and its' subsidiaries - TypeScript advocate and TypeScript leader that is helping PayPal migrate all of their code to - TypeScript and update their infrastructure to support TypeScript applications in addition to giving talks on TypeScript and creating a PayPalTyped monorepo to contain all of PayPal's TypeScript definitions - Introduced react-query and it's philosophy to PayPal engineers to encourage and promote better state management for react apps using REST api's ### Senior Software Engineer @ Slingshot Aerospace Jan 2021 – Jan 2021 | Austin, Texas, United States - Created a buffering/caching system to allow for streaming of thousands of state vectors via a web socket for visualizing orbit propagations in ThreeJS over months and years at 60/90fps. - Architected state management system to handle efficient rendering of React and ThreeJS graphics simultaneously without impacting performance. - Refactored our orbital mechanics education platform from ThreeJS to React-Three-Fiber to bridge the gap between React and ThreeJS and accelerate future development. ### Senior Frontend Engineer @ Koddi Jan 2020 – Jan 2021 - Worked with engineers, designers, product managers and stakeholders to create an entire new Ad Technology platform built in react to consolidate and replace Koddi's current ad tech platform. - Refactored entire project from JavaScript to TypeScript in 2 weeks to help improve code quality and readability across the codebase and enforce strict typing going forward. - Refactored state management in redux from redux-thunk to redux sagas for more robust asynchronous control flow/side-effect management, easier testing and simpler components. - Lead the effort in building a themeable, responsive, documented, tested and accessible component library to power all future Koddi products. ### Front-End Engineer @ Suited Jan 2020 – Jan 2020 - Work with data-scientist, industrial psychologists, product managers and stakeholders to implement production-ready code for Suited's proprietary AI-based recruiting application. - Created new code standards to improve consistency and readability across the code base. - Worked with fellow engineers to create new components for our internal component library. ### UX Front-End Engineer @ Alegion Jan 2019 – Jan 2020 | Austin, Texas Work with product, design, research, and customer success to build prototypes of new features/components/products and improve upon existing interfaces while working closely with engineering to account for current frameworks, libraries, and design patterns. I also help design and execute end-to-end user testing processes that span formulating interface hypotheses to the creation of engineering-ready components. The products/features I build are often for ideas/products we desire to have in the future. So, they are used to validate customer ideas and in many cases used to produce proof of concept work for clients. In addition, by building these prototypes such that they demonstrate the actual product in its' full capacity, I help to identify potential engineering problems months or weeks ahead of time which allows engineering to build products with a more complete understanding of what they were building. ### Front-End Engineer II @ EZTASK Jan 2018 – Jan 2019 | Richmond, Texas As the Lead Front-End Engineer at ezTask my role is to design, develop, test and deploy our many software solutions ranging from our Proprietary Content Management System to our Mobile Application for iOS and Android. It is also my responsibility to ensure that we are using the best possible development tools and practices for our software solutions in addition to ensuring that we use our time efficiently and meet deadlines. ### Front-End Engineer I @ EZTASK Jan 2016 – Jan 2017 All things front-end Guide clients through design process Build/manage themes used for client websites Build client websites Offer support to clients Build/maintain mobile apps for clients ## Education ### Texas A&M University Jan 2013 – Jan 2015 ### BS in Computer Science Texas A&M University Jan 2013 – Jan 2017 ## Contact & Social - LinkedIn: https://linkedin.com/in/zerryhogan - Website: https://jerrywithaz.medium.com - Website: https://zerry.dev - Website: https://zerry.dev --- Source: https://flows.cv/zerry JSON Resume: https://flows.cv/zerry/resume.json Last updated: 2026-03-22
