Implemented centralized peer-to-peer network based on Napster network and decentralized peer-to-peer network based on Chord network using Java and Ruby on Rails.
Those networks are for people connected to the same private network such as campus network or school network to share, search for, and download books. And people can download books directly from other people using peer-to-peer TCP socket connection.
The centralized peer-to-peer network is a server-client structure. The server… Show more

Created a Windows program would enable using a XBox360 controller in place of a keyboard and mouse using C# programming language and .Net framework.

The user can use their XBox360 controller to do a google search, launch their favorite programs, chat with a friend, copy and paste notes into a document, or anything else that a keyboard and mouse could do without having to constantly switch between holding a controller and using the keyboard and mouse.

Implemented a social media web application for book lovers using Ruby on Rails.

Some basic functionalities:
• There are many user positions such as staff, admin, and normal user.
• The user can add new books to the library and remove existing books.
• The user can search and review books.
• The user can create, view, join, and search for book meetings by interest group.
• The user can follow other users and be followed by other users.

Wrote a program in Java implementing some operations on lambda calculus terms using de Bruijn indices. Those operations were converting back and forth between the standard named representation and the de Bruijn representation; capture-avoiding substitution for terms using de Bruijn indices; and some strategy for trying to reduce terms to normal form using de Bruijn indices.

Designed and built an inventory management system using Java, JavaScript, HTML, CSS, Hibernate, and Spring MVC.
The application has some features and functionalities such as ordering items, checking available stocks, adding pre-approved suppliers, etc. The application also provides some basic features such as registering new account, login, resetting password, etc. And the application acts as an intermediary between customers and suppliers.

Implemented Merge Sort on ordered vectors using Agda programming language to show that sorting preserves the length of the input vector and elements in the vector are internally verified to be increasing order.

Designed a database for a package delivery system such as UPS or FedEx:
Customers may use it to schedule pickup of a packet and also check on delivery status. Management may use it to determine overall statistics on number of packages sent in a week or month, the average time taken to move a package from one city to another, etc.

Implemented Elevator System using Scala programming language including use cases, UML diagram, domain-level diagram, etc.
