Duk Kyung (John) Kim

Software Engineer

Woodbridge, VA *********@*****.*** 571-***-****

With over 10 years of experience, I’ve learned that building great projects is a team sport—and I’m not here to play solo. I thrive on collaboration, celebrate shared wins, and believe success tastes better when it’s served with others. I’ve got a soft spot for Blockchain and spend my free time tinkering with hobby projects that occasionally spiral into full-blown experiments. Failure? Just fuel for the fire.

It charges my battery and sharpens my will.

Always ready for the next challenge—preferably one that doesn’t come with a manual.
