Tweet Timeline, 2012
My quick d3.js project. This analytics tool visualizes different types of information associated with a single tweet, allowing you to see the retweet time pattern, the reach of the tweet, as well as the relationship between the users who retweeted. Marketers or content providers can also explore when they should tweet a particular topic in order to maximize its impact. [prototype]

FedEx Internship, 2011
A project from my summer internship at FedEx Services. As a revenue management intern, I developed visual analytics tools that visualize different performance metrics of FedEx’s flight network (such as load factors and freight densities) and how packages shipped using different services are routed throughout the network. The tools facilitate analysis of both historical data and solutions from optimization models to gain insights into current network performance and understand behavior of the optimization models.

Mobility-on-Demand, 2010
A project for Mobility-on-Demand class. The goal of the project is to explore fleet management strategies for balancing the supply and demand of vehicles and parking spaces. Using data from several existing car/bike sharing programs, we analyzed temporal and spatial usage petterns and evaluated efficiency of the systems. Additionally, we participated in a one-week charrette in Óbidos, Portugal with students from the Technical University of Lisbon, the Mayor of Óbidos, and key members of his staff. (with A. Mawani, R.

Flight Schedule Visualization, 2008
A part of my research on robust airline scheduling. To facilitate understanding of a schedule's performance, I developed and made use of visualization in addition to data tables and aggregate statistics. Showing all key pieces of information on the same page, the visualization allows me to easily see interactions among all components and understand how delays and disruptions affect aircraft and passenger connections.

Voice Recognizing Toy, 2007
A senior project for my Bachelor of Engineering degree. We developed user-independent speech recognition software embedded in Digital Signal Processing (DSP) board. Dynamic Time Warping algorithm is used to compare a feature vector extracted from a sampled voice signal to the stored templates. The limited processing power and memory of the DSP board makes this project very challenging. (with C. Boonsongsawat and S. Suppalertporn)

Speechbucks, 2006
A final project for Automatic Speech Recognition class in my senior year. It is a time management game like Diner Dash, where a player has to serve different types of coffee drinks to impatient customers in the queue. Instead of using standard mouse or keyboard input, a player controls the barista by saying (in Thai) the ingredient or action that he/she wants. The speech recognition engine was built using the Hidden Markov Model Toolkit (HTK). (with C. Boonsongsawat and S. Suppalertporn)

TH Baijam, 2006
One of the ten winning Thai text typefaces, awarded by Department of Intellectual Property (DIP) and Software Industry Promotion Agency (SIPA). As an attempt to standardise Thai font usage and avoid being sued by patent holders of foreign-made fonts, in 2010, the fonts have been designated as national fonts that must be used in official documents.
