Looking for a software engineer?

Welcome to all who visit here! I am Jong-Ha Ahn. This is a page for introducing my personal works. I need a purpose to make me go. I think this is the start of something really big. Sometimes that first step is the hardest one, and I've just taken it. Are you looking for a software engineer? I'm available for freelance work. Please contact me.

I love Latte, Mr. Latte is my personal brand.

Great brands aren't built on ads or promotions. I'm always stay humble. There is no room for arrogance. I have the courage to dream big and most importantly don't allow anyone to tell me or convince me that my dreams can't come true.

How can I improve myself and do better tomorrow than I did today?

This is one of my favorite quotes. Good is not good enough. I will do my best. And I always think about "What would you do if you knew you had less than a minute to live?". People who are unable to motivate themselves must be content with mediocrity, no matter how impressive their other talents. My answer is open the notepad and write codes that output "Everything is going to be okay.". I can handle the refactoring and write test of my code if there is a little more time.
