# Kendall L. > Software Engineer Location: San Francisco Bay Area, United States Profile: https://flows.cv/kendalll I've engineered and architected products starting from ground zero. I excel and perform best in fast-paced environments. Describe me? Learn with intention and build with context. Let's get to work. ## Work Experience ### Software Engineer @ Ampure Jan 2025 – Present Posilink & Skylink SaaS ### Software Enginner @ Stytch Jan 2024 – Jan 2025 | United States JS SDK ### Senior Software Engineer @ Chek Jan 2022 – Jan 2024 - Served as the lead Front End Engineer in architecting, building, and maintaining 3 production financial-service applications for: consumers, administrators, and internal superusers, integrating over 100+ APIs - iOS, Android, and web. - Engineered and orchestrated the creation of internal libraries, encompassing core domains such as routing/navigation and API/3rd party external calls, effectively elevating the scalability and robustness of our systems. - Created an in-house theme library that utilized company typography and styles, resulting in improved scalability and component reusability, ultimately reducing development time by threefold. - Designed and developed an in-house module enabling dynamic app permissions management, allowing for the customization of feature visibility and product access based on user roles and preferences. - Developed CI/CD auto-deployment pipelines for both iOS and Android platforms, seamlessly integrating GitHub and Fastlane to optimize development processes and enhance deployment efficiency. - Maximized the performance by: achieving a 70% reduction in web-app load time and an 80% decrease in re-renders. - Integrated a diverse array of third-party plugins, including Stripe, Sentry, Passkeys with 1Password, and OneSignal, seamlessly enhancing functionality, user experience, and security. ### Senior Software Engineer @ Hotpyp Jan 2021 – Jan 2022 - Served as the lead Front End Engineer in building and maintaining a cross platform (mobile & web) security application using Dart and Flutter, integrated 50+ APIs leveraging Patented technology using advanced encryption. - Facilitated and managed development in all front-end service features and product life cycles, with an emphasis on providing architectural reviews and leading discussions on performance and maintainability with other senior engineers. - Led two large refactors, an architecture overhaul from singleton business logic layers to microservices streamlining data flow and a UI revamp - replaced over 40% of the widget tree with reusable and performant components. - Built an internal library of top level services, functions and components including but not limited to: authentication, navigation, error handling, and platform agnostic storage, with a focus on scalability and maintainability. ### Front End Software Engineer @ Hotpyp Jan 2020 – Jan 2021 - 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%. ### Software Engineer @ React Blue (Open Source) Jan 2019 – Jan 2020 - 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 tree Developed and maintained at OS Labs ### Momentum | Tool to Promote Charitable Causes By Leveraging the Power of Social Media @ GitHub Jan 2019 – Jan 2020 Developed the front-end with React adhering to the Flux architecture’s one-way data binding and automated reconciliation with Fiber’s optimized render/commit phases to the Virtual DOM overall reducing unnecessary component re-renders Deployed a Redis caching layer to propagate write-through caching at multiple entry points allowing for both efficient re-fetches of in-memory data and persistence of data ### Dinder Web & Mobile | A cross-platform app for pairing your palate with the perfect meal @ GitHub Jan 2019 – Jan 2020 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 process Web ➢ 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. ### Pick and Choose | A responsive SPA for budget travel and adventure @ GitHub Jan 2019 – Jan 2020 ➢ Engineered a Node.js/Express server to efficiently organize routing and chaining middleware, allowing for simplification of the process surrounding the handling of client-based HTTP requests and subsequent server responses to the front-end. ➢ Incorporated Bcrypts’ one way hashing algorithms to prevent rainbow attacks as well as expediting authentication, and caching sensitive data in a deployed SQL database to allow for one to many relationships and guaranteeing data integrity ## Education ### Finance Concentration University of California, Riverside ## Contact & Social -
