Hello, I'm Lily Lee.

Architected the frontend platform using Domain-Driven Design (DDD), defining clear domain boundaries and feature-based modules across SSR, React, and TypeScript. Led engineering execution as a founding engineer: MVP planning, sprint schedules, hiring, daily demos, QA/testing, and MSW-based mocking. Optimized performance by migrating from CSR to SSR, lazy loading, and authenticated user state handling — 60% faster load times. Built a full-stack analytics dashboard aggregating 3+ external APIs with RESTful APIs, SQL data models, and hourly/daily/regional metrics. Integrated Google Maps (Places API, markers, weather overlays), secure payments, OTP & email verification, and map-based visualizations; deployed production infrastructure on AWS.

Collaborated with senior developers on client project management and system architecture in a fast-paced MERN consulting environment. Designed and implemented RESTful APIs for an internal client management dashboard with secure admin access and full CRUD for client data. Built and maintained React frontends connected to MongoDB, with responsive performance and clean data flow. Assisted in optimizing API request handling and database queries for better response time and scalability.

Spearheaded a real-time chat feature using Firebase for a cross-platform mobile dating app (React Native), improving engagement for 100+ early testers. Coordinated across software development, UI/UX, business, and executive stakeholders on priorities, timelines, and MVP launch preparation.
