- Automated deployment to iOS/Android platform with Git, CircleCI, and Fastlane and Web application with Docker.- Reduced throughput of feedback loop by leveraging dashboards and interfaces integrating Zendesk and Datadog APIs. - Enhanced user experience with native universal linking, light/dark mode, and QR login.- Increased performance by leveraging event-driven architecture, implemented PubNub in a real time messaging feature, and reduced average load time of API calls by 70%.

- Implemented Redux with Thunk middleware to institute modular functionalities and potentially allow asynchronous calls across components, while leveraging Redux’s time-travel debugger to isolate transactions, expediting the debugging process - Reduced expensive D3 re-renders using React’s Profiler to record render/commit phases along with performance metrics, followed by isolating, targeting and stress-testing throughput bottlenecks to ensure robustness of pertinent business logic➢ Memoized props with React Hooks allowing D3 and React to concurrently paint 80% more nodes to the DOM - Leveraged Local Storage to allow multi-platform (Electron and Web application) caching of non-sensitive data, proper state hydration on reload and delayed query executions of data on specific event listeners, which reduced latency by 40% - Integrated React with D3.js to dynamically render potentially deeply nested component data and visualizing hierarchical algorithmic architecture by allowing users to observe subtrees of component dependencies in real-time - Authored a collection of modular traversal and caching algorithms that rapidly inserts, deletes and mutates D3 hierarchy data, as well as implemented data structures to simplify the logic for a undo/redo feature, streamlining user experience - Applied TDD utilizing Jest and Enzyme to develop a suite of unit and integration tests, that expedites iteration and feature addition, improves codebase stability and reduces manual testing while swiftly detecting unexpected outcomes- Utilized React Router to create a control panel interface that establishes static routes in order to dynamically render distinct views, capitalizing on React’s virtual DOM for boosted loading performance while increasing real estate for the D3 treeDeveloped and maintained at OS Labs

Mobile➢ Utilized React Native to architect a mobile version of the existing web application, leveraging native features such as gesture handlers for more fluid and responsive user interaction, and live reload to help consolidate the development processWeb➢ Incorporated React hooks to replace the previous codebase with cleaner, more maintainable, and extendable component code by leveraging useEffect to combine component lifecycle method logic and useState to flatten state initialization➢ Instituted Express’ intuitive routing and middleware capabilities to make API calls to third-party APIs, filtered the data into a digestible format for our React client, and provided relevant response data upon successful API calls.
