Scofield posted, "Today I saw this young homeless man asking for people to take a resume rather than asking for money".
But this weekend, he was sorting through hundreds of missed calls, text messages and emails from recruiters, hiring managers, and strangers offering words of encouragement from all over the world.
It turned out to be the flawless job search strategy.
"You can see my inbox. Pandora. A bunch of startups", he said.
"I'm not trying to take any money, I really do just want a job opportunity".
He had a good job as a web developer at General Motors in Austin, but cashed out his 401k to move to Silicon Valley to launch his own tech startup.
Mesa is meant to help mom and pop food businesses scale up and get their products out to the masses.
"I knew it would be posted on social media, I didn't know it would blow up like this", Casarez told KNTV.More news: Les Moonves Remains At Helm As CBS Investigates Sexual Misconduct Allegations
"I was thinking you know, like this was like my last stop".
People have also taken to Twitter to express their support for Casarez and others experiencing unemployment. After moving to California from Texas, he burned through his savings and was swimming in $80,000 worth of student loan debt.
Casarez, an unemployed web developer from Texas living in a park in Mountain View, California, was wearing his finest tie and holding up a sign that read "HOMELESS, HUNGRY 4 SUCCESS, TAKE A RESUME!"
While some find his story inspiring, others are critical of a work force that makes it hard for outsiders to break in. "And I told myself, 'Why not do that?"
The netizen noted in a separate tweet that she got permission to post the photos.
"It's been happening very quickly, and I'm in shock".
A Friday tweet that featured pictures of Casarez has gone viral, accumulating more than 100,000 retweets and 200,000 likes on Twitter by Monday at 8 a.m. Scofield says she and Casarez spoke on the phone for an hour that night, and he told her more about his journey. He's hoping for a full-time job to keep him off the streets.
