## Role Overview As a Frontend Engineer at Big Wings LLC, I was the sole frontend owner of a production React/TypeScript platform tracking 200+ commercial vehicles. The platform handled real-time GPS feeds, vehicle diagnostics, and live camera streams — directly improving driver safety outcomes. ## Key Deliverables - **Fleet Management System** — Sole frontend owner of a production React/TypeScript platform tracking 200+ commercial vehicles. Built a scalable Redux architecture and a reusable component library adopted across all product verticals. - **Real-Time Safety Infrastructure** — Integrated Samsara ELD APIs + WebSocket for live GPS, diagnostics, and camera feeds. Cut emergency response time 50% (20 → 10 min), directly improving driver safety outcomes at scale. ## Technical Approach The Redux store used a normalized entity structure for vehicle state, enabling O(1) lookups for real-time dashboard updates. WebSocket connections were managed through a custom connection manager with exponential backoff reconnection and message deduplication. The component library was built with compound component patterns for flexible composition across verticals.
