EDWIN LEE

Led frontend development for a rideshare app, creating 90% of all user-facing screens including login, signup, home, ride details, account, and rating system. Developed secure backend for user authentication.

Engineered 95% of a 12,000+ line C# codebase with scalable event pipelines, AI state machines, and modular components. Implemented secure data persistence and biome management system.

Built a C web crawler that parses HTML, extracts internal links, performs depth-limited traversal, and avoids redundant fetches with URL deduplication while saving each fetched page as a separate file.

FlightSim is a modular C++ flight sim with a 100 Hz closed loop integrating sensors, PID/PD control, motor model, and 6 DOF rigid-body dynamics. It includes CSV telemetry, benchmarking tools, and an MCU-style build (flightsim_mcu) sharing the same core via a lightweight port layer for bare-metal use.

Full-stack serverless notes app with Express.js REST API, Prisma ORM, and Supabase PostgreSQL database. Features anonymous user system with localStorage persistence, real-time state management, and optimized connection pooling.

Built backend services for wildlife data ingestion and lookup using FastAPI and PostgreSQL. Integrated Google Gemini API for animal identification and contextual lookup. Implemented secure authentication, role-based access control with PostgreSQL Row Level Security (RLS), input validation, and rate limiting. Developed automated integration tests to validate registration, login, and protected endpoints.

Chrome extension that detects phishing links using multiple detection methods. Analyzes domain age via WHOIS, compares visual elements with perceptual hashing, detects typosquatting patterns, validates SSL certificates, integrates Google Safe Browsing API to cross-check known threats, and automatically blocks input fields on suspicious sites to prevent credential theft and credit card information theft.

An interactive 3D globe that shows live top headlines for any country you click. Drag to rotate, scroll to zoom, click a country to see its news. Built with pure TypeScript.
