Ying Chyi Gooi

Hello, I'm Gooi.

I am a software engineer based in Brooklyn, NY.

I am a co-creator and software engineer of SpaceCraft — an open-source, in-browser REPL (Read-Evaluate-Print-Loop) that enables real-time collaboration between users.

More about me

// Recent Project

SpaceCraft

SpaceCraft is an open-source, real-time, collaborative REPL (Read-Evaluate-Print-Loop) that enables pair-programming without any additional setup.

SpaceCraft is built using a Node.js server that manages REPL code evaluation and connects multiple clients through WebSockets. SpaceCraft is deployed with Docker and scaled to handle multiple user sessions using a reverse proxy server.

Try out the demo here.

// Past event

Tech Talk

I presented my journey on building SpaceCraft for the QueensJS Meetup on February 6, 2019.

SpaceCraft:
Proxy Server

I built a reverse proxy server from scratch using Node.js and Docker API which integrates with SpaceCraft. The proxy server manages multiple user sessions, initializes containers and forwards clients' requests to the appropriate containers.

A Sinatra application that allows users to buy or sell mocked digital currencies based on real-time market data. The back-end is integrated with CryptoCompare API to track cryptocurrency prices.
