Responsive Web Design for a dashboard

Screencast shows the same web-dashboard displayed on three different devices – MacBook, iPad, and iPhone See in Action

With the increasing popularity of iPads and iPhones, I was asked me to create a web-based dashboard to provide an optimal viewing experience with all their devices – iPads, iPhones, and Macbooks using just a single-code base. I was able to achieve these requirements using responsive web design techniques with HTML5, javascript and CSS3.

The dashboard contains several distinct widgets:
1.) Multiple carousels (swiping of data) responds to both mouse and touch gestures to swipe the card to view additional sets of data.
2.) A slider to select the date and time range. The slider transforms into the standard iPhone time picker when the web-dashboard is viewed on an iPhone.
3.) Sophisticated charts embedded inside of other charts.
4.) Grids to display data
5.) Persistent Web Design techniques to retain user’s viewing settings

In addition to javascript and CSS3. I used the following technologies and plugins:

  • Bryntum Scheduler and Gantt Charts
  • Sencha EXTJS 4.0
  • jQuery
  • jQuery.ContentCarousel plugin
  • Developr theming
  • glDatePicker
  • jQRangeSlider
  • jQuery.blockUI plugin
  • mobiScroll

My Toddler Can Learn Names

My Child Can Learn Names

I have been buying a lot of apps from the AppStore and Google Play Market for my toddler. And then I thought, “Hey, why don’t I make my own app?!”

In my limited spare time, I made an app that teaches my 2-year old son the names of his family and favorite cartoon characters.

There are apps to teach your toddler animal names, colors, shapes, vehicles… but what about apps to teach your toddler the names of friends and loved ones? This app can teach your toddler the names of his/her family and friends in a fun and easy to play game.

Download the game from Google Play or Play the game online

This game was created using HTML5, CSS3, jQuery, Javascript and a plugin to stretch images.

The Jeremy Lin Video Game for your phone, tablet and desktop!


It’s been awhile since I posted something I’ve done. I’ve been doing amazing things at Apple Inc, which has kept me busy. Awhile back, I did begin a project to help me learn all of HTML5 features. I decided to make a Jeremy Lin app that incorporates all of the new and cool HTML5 features. I also wanted this app/website to be responsive. This app should work and look nice on all devices – desktop, smartphone, tablet. Here is my excerpt from the Google Play store,

This is the Jeremy Lin Linsanity Video Game. You decide which play to make and watch your stats increase. Watch hundreds with highlight clips of Jeremy Lin’s NBA career. This app also includes Jeremy Lin’s twitter feed, real-time stats, youtube highlight clips, the Houston Rocket’s schedule, fan photos, news, biography, etc.

Play the Jeremy Lin video game from your desktop, smartphone, or tablet here

Facebook login integration, Paypal transactions, Google language translations, Javascript snippets, Memberships

Have you ever wanted to learn how to invest in stocks? If yes, you’ll need to learn chinese 🙂

So a couple months ago, a former work colleague and friend asked me to start the development of a website for him. He’s taken a successful English-based website and created a website for Chinese-speaking investors. His website is now live at www.5168options.com

His website is basically a free and paid membership-based content management system. Users who pay for the membership are given access to highly informative and frequently updated content. He needed a quick, yet working mock-up of the site to present to his inner circle.

I created his website using Dreamweaver as the developer environment. I included the Facebook login integration into the site for a more user-friendly experience. The paid transactions are done with Paypal’s e-commerce Merchant Services. The language translation between Chinese Simplified to Chinese Traditional was done with Google’s Website Translator. ASP and Access database stores the user login data and memberships. And the stock ticker is simply a javascript snippet.

update: due to time contraints I have relieved myself from the day-to-day maintenance of the site.

This is a test

My Phở app is now available for all mobile devices

Everything you need for the delicious Vietnamese noodle soup, Phở, is in this app.   Quickly get a list of all the Pho restaurants near you and plot them all on a map. Or enter in a city name to get all the Pho places in that city. Also included is a recipe to make your own Pho. View the photo gallery of all the Pho toppings you usually get in a restaurant – brisket, steak, fatty brisket, tai, chin, gau, pho ga, etc.  Finally, an app my parents would use.

For Google Android users, download the app in the Google Play store here and install for free,

For Apple iPhone users, use the Safari browser to access the web app here,

This app was developed using Sencha Touch 2.0.   Sencha Touch 2.0 is a javascript framework using HTML5/javascript technologies.  The data is taken from Yelp’s Webservice API.  I added Google’s geolocation APIs to plot the restaurants on the map.  The images for the Pho toppings were taken with my Canon t2i and photoshopped by me.

update: There are some pros and cons to using Sencha Touch over other mobile-specific frameworks like jQueryMobile.  I’m currently working on another smartphone app using jQuery Mobile and will have it available soon.

My web-based customer support portal!

web-based customer portal

The Realization technical support team needed a way to streamline their processes with customers using a web-based application. They occasionally conduct workshops and learning sessions and needed a way for our clients to register for these classes. The IT team also needed a way for certain clients to be allowed to download files and software releases. It was my responsibility to come up with a design and take it to completion.

I created this web application using ASP.Net with SQL Server as the database. The application administrator section allows the admin to add/remove workshops, upload files for users to download, and set the user’s permissions.

ChartFX can’t do it? Don’t worry, I can.

The chart is an image, the data grid is html

SoftwareFX’s ChartFX component is very useful in displaying so many different charts and in so many different ways. However, the current version of ChartFX lacks the ability to display a grid of data alongside with the bars in the chart. Instead of whining and crying about it, I came up with a solution.

Using HTML, I overlayed a grid on top of a chart and I was able to display the  grid of data, coinciding with the chart’s bars. With some improvisation and hard work, this idea worked like a charm.

*update: The newer version of ChartFX, ChartFX.Net, now comes with a grid data, but doesn’t work very smoothly. I created another version of this chart data grid for the .net version with scrolling data.
