Phroni (2009-present)

When users come across an interesting keyword while reading texts, they typically want to search and get further information on it. However, current smartphones do not provide an easy way to this; It requires highly tedious steps such as selecting the keyword by holding and accurately swiping fingers on the screen, copying and pasting the keyword to the search box, and selecting a desired link from the search results.

Phroni addresses this problem by converting notable keywords that users might want to search into links. It automatically extracts keywords from texts using a machine-learning algorithm and enables users to perform a search to Google, Wikipedia, Twitter, and other relevant sources by just tapping it.

Keyword Now (2010-2011)

Keyword Now is an iOS app that allows users to check the most popular keyword rankings on the web or on TV. The app periodically generates keyword rankings by crawling and aggregating several web sources.

I initially developed this app within 3 days as a teaching material of Appcelerator Titanium Mobile Workshop at Keio SFC. The app has been downloaded over 80,000 times from the App Store.

Nomadic Node / NAT Traversal SDK (2003-2005)

Normadic Node (formerly NAT Traversal SDK) is a middleware that enables direct communication between nodes having private IP adoresses.

Under the IPv4 Internet, there are not enough IP addresses to distribute globally unique addresses to each node. Therefore, most nodes have private IP addresses, which are not unique across the Internet. Therefore, it is basically impossible to directly communicate between private nodes.

NAT Traversal SDK addresses this problem using several unique methods including UPnP and STUN and enables direct communication between private nodes.
