  • image de Greg B. Twilio, Golang, Postgresql $2000.00 AUD

    “I subcontracted Mario to do a project that I didn't have time to develop myself. This is the toughest gig, because he had to prove to another programmer that he could program well. I carefully reviewed everything that Mario did because my reputation was on the line when I delivered it. I can honestly say that I'm happy with every line of code that he wrote, which -- as people who know me can attest -- is high praise indeed.”
