Sean Kim Email and Phone Number
Can you imagine a 11-year-old kid just going in and out of Windows folders for hours? That kid was me the first night my family bought a computer. I was in awe about the new technology, and it was fun enough even though I ran the first software months later. I can confidently say that I am a curiosity driven person. I dig deep into areas that interest me, and it led me to photography. The whole process of photography, I found, was unexpectedly similar to software development. Before taking a shot, I had to think of many factors such as light of the angle, framing, and trail of story to be told. After that, I would have to micro adjust the settings on camera. However many times it took, I worked up until I took the optimal shot that I was satisfied, and it gave me thrills.Now, my passion lies in software development. Even before typing into an IDE, I would have to carefully design the logical flow, decide which pathway to take to arrive at a solution, and consider how it would be viewed to the user. After giving the program its first run, I would face many errors. I fix up the errors, re-adjust the logical flow, and better its appearance to the users. I would have to repeat this process until I have a work of art that I can confidently present to the users.All in all, I anticipate an astonishing experience in my future career where I can concentrate all my curiosity into.Thank you.
