2. The beginning

3. I started programming very late and before I
learned it, my life was meaningless.

When I first learned C language at winter vacation in
my sophomore, WOW !

When I first learned C language at winter vacation in
my sophomore, WOW !
My teacher was a friend of my older brother and I still think he
was a real geek.
I decided "I will always be a developer, always"

6. And next year I joined a programmer’s club in my
university. There I exhibited my first program.
It was just 3D editor, running on MS-DOS with
specific video-card, drawing 3 primitive objects
(sphere, cylinder, cude) by ‘ray-tracing’ and save it
to GIF file.

8. Next year I joined SSM(SAMSUNG S/W
Membership). SSM is kind of incubator, support
program for University students.
The examiners liked my first program and I became
the 1st member of branch at my hometown.

9. When I graduate, there was s S/W competition
held by SAMSUNG Electronics.

10. And I made this 3d sports game with my
fellow in SSM and Bronze prize.
This ran on MS-DOS, written in WatcomC++.

I took 3d coord. system, Physics
(collision, particle) routine.

11. After graduated I started my career as a
System Engineer at SAMSUNG Electronics.
And I didn’t like it because System
Engineering is not my job. I wanted to
write codes.

12. Learn how to dance

13. My job was heavily related to the Information Security and
TCP/IP networking. OS was MS-Windows system only. I
think I learned the basics of S/W in those 10 years.

14. One day a fellow of mine at SSM offered me to join
his company. And I joined.
I took over the development of their ‘terminal
emulator’ (you know CRT, or HyperTerminal?) and it
was 3rd famous one here.

15. And made a ‘file encryption’ program.
Which can encrypt your files locally and upload to a
dedicated server.
This is still on sale

16. Meanwhile, one of my cousins were the manager at
a Network Security company. And he asked me to
work together.

17. There I made a VPN Client
I learned device drivers and TCP/IP fundamentals. And
till this I had only 2 or 3 members or sometimes I alone
in my team so I did major of coding.

18. And made Korea’s first Worm protection solution.
This was promissing, team grew bigger.

19. I was happy with that company and learned a lot but
the managements did some manipulation in stock
market and they put into jail.
company situation got worse and many people left
that company.

20. and I joined AhnLab, the #1 AntiVirus company here
in Korea
There I made privacy information protection solution.
But we were too early, or maybe we didn’t read the
market’s needs right. The speed of project went slow.

21. Varieties
&
sweet failures

22. Meanwhile, a company in Japan contacted me.
I wanted to experience the different countries
and decided to go there.

23. In my first company in Japan,
I made Flash book viewer
generating Flash book contents
from scanned images.
And Flash comic viewer &
contents publishing
tool/server.

24. New Languages and environments like
C#,PHP,ASP.Net,ActionScript,FlashLite,Japanese
Mobile Phone, etc.
No problem and fun.
And I had chance to work with Japanese, Indian,
Canadian, Serbian.. We were good friends.

25. And maybe Adobe Japan liked our solution? it was
almost close to M&A between them.
But didn’t work out well.
Financial situation got bad and I decided to go Tokyo
for new opportunity.

26. Joined to Japan branch of Korean
Online Game company.
Assigned project was Japanese High school Baseball
Online Game (like above).
I made Game Server(Linux,epoll), and Windows
network library & sample. The partner company was
making Windows Game itself.

27. but soon.. not again. Financial
problem..
Newcomers and uncertain project
members were laid off.
Around that time, I got terrible emotional
scar from a colleague Planner.
So I thought ok.. I will find another job.

28. I found a company, joined as a contract employee.
I did some RoR server stuffs and FlashLite
programming. The CEO himself was a power
developer and I learned a lot.

29. we were working with developers
in Lithuania, designers in Indonesia.
Because of time difference, the
working hours were about 13
hours a day. Frankly13 hours are
nothing. almost every Koreans and
Japanese do.
But about the time, I was totally
exhausted. I couldn’t get back
from the shock of previous
company.

30. I decided to take a rest. So I was still in contract,
not enough salary for household.
So I did some freelancing, working at home.

31. Coming back home

32. The CTO from ‘Oullim’ my previous company
back in Korea made his own company. He gave me
freelancing job and it was finished.
He asked me to come back and work together.

33. I helped making NAC (Network
Admission Control) solutions.
Android/iPhone,Flex,Web browser
plugins, etc.

34. I admire the CEO and CTO there. And most the
members I already have been known of.
But some people didn’t want me there.

35. One day, one of my old colleague called from USA,
telling “Hey, a bro I admire is trying to launch a
new company. I think you are a good fit there. I’m
also founder there. Would you join?”
Sure, I’d like to.

36. In new company
Habitus(now NeoFect), I
made Social Game.

37. New environment & area. Cocos2d-X, Location
based Social Game.
I wrote code for Server(RoR), Client(Android/iOS).
Founders were all great. USA doctors, MBAs,
Korea number one Universities. And I was CTO
there. Cool

38. But not enough users were interested.
Plans are changing and not realistic.
Project periods delayed.
Co-founding company left.
Still were able to manage the company, financially.
But I was more and more out of their school tie.
Nobody understood technical issues or plans I
make, or would believe.

39. I was doing free lancing after that company.
One day I visited a company for a ‘possible
outsourcing contract’. And they started to
interview me without business meeting.
The president there explained his business idea
and I liked it. I saw possibility.

40. There I made a SNS service for Mobile Gamers.

41. SNS for movie sharing (OpenSource)
http://code.google.com/p/chococam/
And involved in every developments, in-house &
outsourcing.

42. And involved in business meeting, did role of
bridge between investors and my company.
But it didn’t go well.
I couldn’t successfully arrange the investments.

43. It’s all about my history.

44. Anatomy of me

45. Programming Languages

46. Tech Experiences

47. Work experiences

48. So I am black.
pitch black.

49. And I think
I’m kinda Geek

50. Sensitive
