Pound Pong (repo)

Initially, the idea started out as a web app that would keep track of all of the Ping Pong matches that went on at the Yelp office. However, the project quickly transitioned into much more. Using an RFID scanner hooked up to an Arduino which is hooked up to the iPad, we can communicate with the application using our badges which all happen to be RFID. From there, we can ‘badge’ into our matches and record the winner in a seamless transaction using nothing more than our badges and a single tap to label the winner. Results are sent to a simple Flask server through a JSON API where they are stored in a Mongo Database. This was a project that I worked on with a group of 4 at our semi-annual Yelp hackathon. We had two people working on the Flask server / front-end of the website and two of us (including me) working on the iPad app and getting it to communicate with the RFID scanner.

Global Snapshot (demo) (repo)

Working on a group of three at the LinkedIn Hack Day 2013, we buit a real-time Twitter and Flickr visualizer. Watch as tweets and photos fall onto the map and as the photos form a real-time stream on the sidebar. Want to see more photos? Simply expand the sidebar by pressing the toggle button on the bottom right. Hover over any of the dots to view the tweet or photo from that location. Node.js backend while working with several APIs including Google Maps, Twitter Real-time, and Flickr Real-time. Also uses for sending the data to the browser in real-time.

An iOS app search engine. Data is gathered using a scrapper that I built and stored in a Postgres database. Search is done by indexing the database and using Postgres built-in full-text search.

Rubik’s Detection (repo)

The idea was simple, take a web camera, use it to detect the colors of a rubik’s cube that a user holds up to the screen. Analyze the colors, pass the output to a solver and display the necessary steps to solve the cube. It actually worked and we won third place at a hackathon as a result. My main role was working on detecting the colors by holding up the rubik’s cube to your screen.
