Hi, I’m Amanda Chen. I’m a senior frontend engineer based in New York, focused on building performant, accessible, and maintainable web applications using modern JavaScript and TypeScript ecosystems. I design modular component architectures, optimize rendering pipelines and data flows, and strive to deliver high-quality user experiences across enterprise products. I enjoy collaborating with product, design, and backend teams to ship responsive interfaces that scale, prioritize WCAG-compliant accessibility, and improve frontend reliability. In my roles at Flex and Squarespace, I’ve led SSR-driven interfaces, real-time dashboards, and cohesive Design System libraries that boost speed, consistency, and developer productivity.

Work Experience

Senior Software Engineer at Flex
September 1, 2024 - Present
Architected scalable React + Next.js payment scheduling interfaces with server-side rendering and dynamic routing, enabling tenants to visualize flexible payment plans and configure customized schedules while reducing initial page load time. Integrated type-safe TypeScript REST APIs into data-fetching layers to deliver secure, real-time access to payment histories and statuses. Engineered intuitive configuration views translating complex rent-splitting rules into clear UI components and built real-time dashboards for payment statuses and landlord activity. Implemented event-driven UI updates via Kafka-streamed events for instant confirmations and balance updates, and designed caching and optimistic UI patterns to minimize latency during high-traffic periods. Added robust error boundaries and rollback UI flows to handle failures gracefully. Collaborated with backend to optimize API contracts and designed a cohesive Design System of reusable payment components; built GitHub Actions pipel
Software Engineer at Squarespace

Architected an enterprise Angular application for an AI-driven event product recommendation and approval system, supporting multi-tenant storefronts with complex rule configurations and approval workflows. Designed reactive state management using RxJS and NgRx to handle multi-layered rule configurations and real-time validation. Optimized rendering with memoized selectors, Angular CDK virtual scrolling, and OnPush change detection to efficiently handle datasets over 10,000 records. Built type-safe REST API client services with error handling and retry logic, and implemented polling with RxJS to synchronize background job statuses with live dashboards. Integrated Elasticsearch query builders with debounced search inputs and client-side caching for sub-300ms filtering. Developed optimistic UI patterns with immediate feedback and graceful rollback. Created reusable Angular components and data transformation pipelines, and led end-to-end testing with Jasmine, Karma, and Protractor integrat
