The document discusses the author's work experience developing educational and industrial software over 12 years. For 5 years at SMART, the author worked on several educational projects including Notebook software for Windows, Mac, and Linux as well as other programs. The software had to have user-friendly features like those shown in assessment and Arabic language screenshots. For 7 years at DongFang, the author worked on 4 industrial supervisory control and data acquisition (SCADA) projects requiring high performance and reliability, such as responding to accidents within 1-2 seconds. One system, DF2000E, integrated real-time, editing, and study states as shown in screenshots.

2. At SMART
I have worked for several Educational projects
for 5 years at SMART, which includes
Notebook 10.1-10.8, 11.0 on Win/Mac/Linux;
Response/Senteo on Win/Mac; LanguageSetup
on Win/Linux; Notebook & Board Tools on all
platforms...
Educational software has many user friendly
features. The next picture is an assessment in
Response and 2nd picture is Arbic.

5. At DongFang
I have worked for 4 SCADA projects for 7
years. A real time system needs high
performance - when an accident happens
hundreds of KM away, my program has to
finished all response in 1-2 seconds, which
include decoding the signal, log it, send the
event to other computers, load the graph, print
the event, speak to the operator... Another
request is high reliable... Another request is
high reliable - the stopping time can only be 2
minutes in one year.

6. At DongFang
DF2000E is an integrated SCADA system,
which includes three states: real time, edit and
study.
The next picture is the real state. The 2nd one
is the edit state, which is composed by 3 split
view: equipment list (tree view), graph editor,
topology editor.
