A homeless man from California with an indomitable work ethic has received hundreds of job offers after a picture of his unique "hungry" sign went viral on Twitter.

David Casarez, 26, is a software developer with three years of job experience and a college degree. But when he moved to the San Francisco Bay Area last September with a dream founding a startup company, he found himself down on his luck, Casarez told KNTV. He couldn't find a job, soon ran out of money, and eventually became homeless.

But he refused to resort to begging. Instead, he put on his best clothes and made a sign that read, "Homeless Hungry 4 Success Take a Resume."

He was standing on the side of the road, handing out copies of his resume when he was spotted by Jasmine Scofield. She took a picture of him and his resume and posted it to social media, writing if "anyone in the Silicon Valley could help him out, that would be amazing." Her post went viral, with more than 216,000 likes and 134,000 retweets.

"I knew it would be posted on social media, I didn’t know it would blow up like this," Casarez said. "I’m trying not to take any money, I really do just want a job opportunity, that’s all I’m asking."

According to KOAT, since the post went viral Casarez has received at least 200 job offers from tech companies including Google, Netfliz, LinkedIn, and more, proof that you should never give up on your dreams and work hard.
