The VR World Prototype Building Project made it possible for
clients to experience Technomart, Korea’s largest electronics
shopping mall. The virtual environment enabled chatting and
walking through the mall. Up to 256 users could occupy the
same channel. |

|
| |
- Client
: ETRI(Electronics
and Telecommunications Research Institute)
- Platform : UNIX, GCC, CGI
- Summary:
This was a construction project for an ATM-based MPEG-2 Streaming
Service. I developed an EPG (electronic program guide) and
a Program Management System. I also designed web-to-streaming
player integration without ActiveX technology. |

- Client:
E-Motion
- Platform : Windows NT, SQL Server, VC++, Delphi
- Summary:
I constructed a Push Technology Based Intranet System for
personal/group messaging, and for users to exchange messages
or documents using the P2P Document Transfer Service. Managers
could also use the service to send notices or orders directly
to their staff.
|

- Client:
E-Motion
- Platform: Windows, Linux, Solaris, IRIX, FreeBSD, VC++,
GCC
- Summary:
I researched, first, the tools used by those unfamiliar with
programming when creating dynamic websites related to bulletin
boards, membership and e-commerce. I discovered several methods,
but none quite appropriate for the average non-programmer.
So I created “EasyDB,” which lets users define their data,
automatically generate a CGI source and compile it. Users
could also design a dynamic page using a template separated
by binary. |

- Platform: UNIX, GCC, ISAM
- Site : www.samsungfn.com
- Summary:
SamsungFn.com’s main page had accumulated heavy traffic due
to its finance and stock data. To reduce traffic, I developed
a daemon to freeze complex the main page to a static page
periodically, except in private areas containing personal
user information. The task required a Dynamic to Static page
Publisher, a daemon Service and Interval Based Publishing.

I focused on how children could handle the Web more easily,
and on whether a customized browser for kids would help. To
improve usability for children, I helped combine browser,
mail and chatting services in a unified interface. We also
offered web and search services, since evaluated by the Junior
NAVER service. The task also required Agent Technology, MIME
Type Mail support and a Kid Default Web Service (with NAVER).

- Summary:
To create a first membership card for Hyundai Oilbank, one
of the largest oil refineries in Korea, we fixed an offline
user DB containing millions of people’s information. With
so much wrong and redundant data, I analyzed the pattern of
data and created a migration filter and verification tool
for DB Cleaning. |
|

- Client
: E-Motion
- Platform : VC++, GCC
- Summary:
I created a CGI Builder (upgraded from “EasyDB”) for increased
interacting web applications. It preceded the CMS(Content
Management System) and supported a template-based Dynamic
Data (DB or File) Publish and Input/Modify/List/Article/Delete
Functional CGI Generation. It let users build their own data
flow using the CGI Builder. It also supported Cross-Platform
CGI Generation. |

- Platform : Windows 2000, SQL-Server, ISAPI, ASP, Delphi
- Site : Korea.com
- Summary:
I took charge of building the contents portion for a “mega
portal” for Thrunet, an enterprise listed in NASDAQ. The portal
combined 4C (Contents, Communication, Commerce, Community).
The large-scale project involved 650 servers (now 850), millions
of pages, 200 content providers and 100 means of content providing.
I designed a content lifecycle and established various developing
policies. I also oversaw a staff of 80. This portal is considered
the biggest window-based Portal Site, as showcased in Microsoft.

- Client
: Thrunet
- Platform : Windows 2000, SQL-Server, ISAPI, ASP, Delphi
- Summary:
I served as project manager for the creation of an eCMS, an
upgrade from a CGI Builder 2.0. The system contained a feature
to manage contents and supported an area ACL which permitted
or denied workers/work groups in a page consisting of different
sections. As if using Legos, users could insert or replace
section blocks of pages. Distinctive from other solutions,
eCMS supported authorizing techniques enabling the end-user
to make dynamic (logical) pages without any programming techniques.
The work required up to 200 content replication nodes, up
to 200 CP(Content Provider), up to 50GB contents uploaded
per day, analysis of content workflow per service and more.

- Client
: SK
Global
- Platform : Windows 2000, COM+, ASP, VB
- Site : Wizwid.com
- Summary:
Created “Wizwid.com,” a new business model enabling automatic
logistics. The site did not sell domestic products, but global
addresses. If a user joined the service, he received his own
address in the U.S., which allowed him access to everything
in U.S. domestic markets. To increase the flexibility of global
logistics, I created a workflow system to design global logistics
and to track processes easily. “Wizwid.com” became the best
global shopping mall and logistic service in Korea. |

- Summary:
Shinhan Financial Group, the 2nd largest financial group in
Korea, needed a financial portal to support all of its services
including insurance, banking and selling of financial funds.
It also needed a personal financial dashboard through which
users could see all details of accounts, credit card activity,
insurance and e-mail on one screen. I adhered to strict national
security policies (ones more stringent than in the U.S.) by
using ActiveX personal key security. I created an aggregation
agent supporting all security solutions in Korea and constructed
a parallel aggregation system distributing aggregation requests
to 200 agent servers. |

in an “Emoden.com” project. It required developing a site
aggregation agent, an Aggregation Authoring Tool & SDK, 128-bit
private key-based site aggregation (using ActiveX Plug-in,
more restrictive than SSL) and verification from Yodlee.

of DA (Digital Appliance). The system connects attached equipment
of IB (Intelligent Building) with PLC (Power Line Communication),
collects data, and then forecasts mechanical defects based
on past records. This revolutionary project changes the old
concept of A/S (After Service) to B/S (Before Service), letting
users examine a product before the product breaks down. |
