Jeffrey Cheung πŸ‘¨β€πŸ’»

Lead Full Stack Engineer | Performance & Distributed Systems Expert

πŸ“ Vancouver, BC | πŸ“§ [email protected]

I specialize in scaling high traffic digital platforms and optimizing customer journey experiences through the full request lifecycle. My focus is engineering distributed, cloud native solutions that translate directly into business value and exceptional user experience.

My recent work highlights include:

  • Architectural Migration: Led migration of 400K+ documents to a Payload CMS/MongoDB platform, reducing cloud expenses by 70%.
  • Microservices Architecture: Re-architected a legacy endpoint to a Golang RPC microservice on a private Fly.io network, boosting speed by 4x and improving system reliability.
  • Edge Computing: Utilized Cloudflare Workers and advanced caching to optimize the request lifecycle, ensuring high Core Web Vitals (CWV) across a network supporting 3M+ monthly sessions.

I am dedicated to crafting clean, robust, and highly performant code, constantly exploring new architecture to solve large scale problems.
