Places I’m At

My Products / Projects

jsonip.com – Used by hundreds of users and supports over 10+ million requests a day. This is the most successful product I’ve personally built. The service returns the client’s IP address in a JSON object. Supports direct requests, JSONP, and CORS requests.

jsonip Pro – An upcoming pro version of jsonip.com.

Helium CSS – My biggest open source project with over 3500+ followers. Helium is a client-side tool that helps web developers discover unused CSS on their sites.

Popped At – Popped At is a visualization of images being shared in real-time via Twitter.

When-Then – One of the biggest uses of Promises is the use-case of firing off multiple asynchronous requests and then doing something with the combined results. When-Then is a short utility that handles just that situation and tries to simplify the code needed to set this up.

  1. Hello there, I’m just curious about why you use geuis as your online name, does it have a meaning for you?
    Because my name is geuis, however it doesn’t have specific meaning in my language.
