First open-source integrated development environment (IDE) for building React web applications• Leveraged React’s capability of constructing reusable components to create a dynamically rendered user interface, leading to a highly scalable UI, an increase in developer productivity, and performance improvements via the Virtual DOM feature of React• Architected an Electron cross-platform desktop application to leverage powerful web-based technologies such as React to build a dynamic UI/UX that renders real-time changes made to the application’s codebase, resulting in a streamlined development process• Deployed Redux to effectively manage a centralized application state, allowing anti-patterns like prop-drilling to be mitigated as all components have access to the centralized state, resulting in consistent application behavior and increased application scalability• Adopted Flow Parser to generate an Abstract Syntax Tree that represents the source code of the application imported into Reactide• Refactored the recursive algorithm so it is capable of traversing deeply nested state objects found in Abstract Syntax Tree nodes, leading to the ability for Reactide to produce a visual representation of component hierarchy along with the state of components• Utilized Monaco editor to produce an integrated development environment that includes features such as an in-application code editor that includes syntax highlighting to allow for a native code development experience that facilitates the development process• Incorporated Xterm terminal emulator to create a console terminal that allows for the execution of shell commands within the IDE• Harnessed the power of Node.js child_process module for its ability to spawn child processes that can execute long-running tasks, resulting in a main process that remains performant, leading to an application able to serve incoming requests and stay responsive

Waterford, Munster, Ie

Consultancy Specializing in Modern Full-Stack JavaScript Application Development• Leveraged TypeScript and it’s native tooling to enhance the developer’s experience, improve application debugging, as well as to enforce strong typing throughout the codebase, resulting in an application with greater maintainability, readability, and scalability• Integrated React Server Components for their ability to be rendered on the server and to access server-side data sources directly, resulting in a simplified API architecture, reduced application bundle size, and a more performant, lighter-weight application• Used NextJS to enable server-side rendering (SSR), avoiding the freezing of the browser in order to download/execute source code, resulting in decreased total blocking time (TBT), enhanced search engine optimization (SEO), and an overall better user experience• Employed GraphQL for its ability to solve over-fetching/under-fetching by retrieving multiple resources in a single request as well as for its self-documenting capacity, resulting in a more streamlined data-fetching workflow and an increase in development speed• Utilized Storybook and it’s isolated user-interface (UI) playground to cultivate accessible (a11y) components of the UI in real-time with various stakeholders, leading to both the facilitation & acceleration of collaboration amongst the Product team(s)• Incorporated Sanity headless Content Management System (CMS) to leverage its flexible data modeling and its intuitive, user-friendly content editor, facilitating rapid content customization & enabling real-time content iteration among all stakeholders• Augmented Styled Components for the ability to implement CSS-in-JS and to narrow the scope of declared styles to specific components, leading to an expedited development process by eliminating any possible CSS specificity conflicts that could arise• Integrated Tailwind to reduce amount of CSS needed and to optimize CSS by removing unused styling

Led teams of engineers through rapid application development, precise technical communication, and TDD workflow• Leveraged Docker’s OS-level virtualization to create containerized run-time environments, facilitating consistent application behavior across all platforms, hyper-scalability of the application, and improvements to team development workflow/code integration processes• Employed Travis CI via Github webhook with custom bash scripts for continuous deployment on AWS, improving time-to-production• Harnessed React’s higher-order component (HOC) technique to handle cross-cutting concerns and maximize the reusability of a component’s functionality across multiple other components, resulting in strict, configurable, and reusable component-hierarchies• Utilized Redux-Form to connect the application’s form-state to a single source of truth (SSOT) to produce predictable application behavior as well as to format, parse, and normalize user inputs, fostering a granular step-through form-debugging capability• Implemented React-Router to architect a single-page application that dynamically routes client-side views via application tasks, streamlining the display of component-hierarchies, improving code clarity, and also bolstering a more seamless user experience• Configured YAML files for a React higher-order component (HOC) to recursively parse JSON and create renderable JSX components, resulting in the automation of component-hierarchy creation and spanning application accessibility to non-technical professionals• Leveraged PostgreSQL database that adheres to the ACID standard in order to persist application state/data and ensure the atomicity, integrity, security, and consistency of all transactions occurring between the application’s users and the SQL database• Onboard/train software engineers in full-stack codebases, with workshops on the thread of execution, execution contexts, and JIT

Served as Senior System Engineer for integrations of a machine learning platform deployed throughout Southeast Asia• Maintained Python codebase via script updates and installed application patches received over a virtual private network (VPN)• Leveraged a Django based web-application to effectively control, monitor and troubleshoot the machine learning platform, as well as maintain its ancillary systems, from single-mode fiber optics to CISCO switches to Linux servers, all to maintain a system uptime of ~99.99% • Enhanced UI/UX of proprietary web application by employing HTML, CSS, and JavaScript to produce a dynamic application• Performed system administrator tasks via the CLI for a Linux Red Hat server to ensure proper user access & system maintenance
