This was my latest project using GTFS (General Transit Feed Specification) data from the Port Authority of New York and New Jersey to provide PATH riders with train arrival information (according to the schedule) on their computers, tablets or smartphones, station by station. I also learned ASP.NET URL routing through this project, which is useful for SEO and user experience.

NextPATH also featured a full screen interface (which does not support mobile phones) and Instant News (feed from Google News; styles made with Bootstrap).

This was the client management system for Expat US. I used ASP.NET 4 and Microsoft SQL Server 2012 to build the application for their business, and hosted it on GoDaddy.

Some pages were responsive design. In order to improve security and user privacy, SSL Certificate was also added recently.

Expat US Mobile

This was the mobile version of Expat US company website. jQuery Mobile was employed as the template.

Due to the high cost of web hosting plans, Metrofriend live site is no longer available.

This was a class final project (CS 543 Principles of Computer Mediated Entertainment) at Stevens during Fall 2013 semester. Metrofriend aimed to connect NYC subway commuters together on social media, letting them find friends who start and stop from same (or nearby) stations. App framework was identical to myexpatus (ASP.NET 4 Web Forms and SQL Server 2012), but more JavaScript and jQuery elements were added to improve user experience.

The site also featured a station locator (using Google Map API), as well as real-time service alerts (using official data from MTA).

I helped Soltek move their old Magento website to a new one, migrate its MySQL database and configurations, and install a new template.

Soltek appreciates your business.

Countdown Clock

I wrote a useful countdown clock with Javascript / jQuery, which could be used on both desktop and mobile devices. Desktop notification is also supported in some browsers.
