  • Samuel Otterman - coworker at Capabuild

    I had the pleasure of working with Joshua for two years at Capabuild. Not only did he demonstrate his solid knowledge of frontend development best practices while working on our React Native application, but he also was the core developer for handling LIDAR and automated interior mapping.
    On top of his technical skills, his friendliness and humility made him the ideal teammate; he was as comfortable giving constructive criticism as he was taking it.
    Joshua isn't just a good team member, he will truly elevate any team that he is on!

  • Dan Lilienblum - coworker at Dash Core Group

    It's a great pleasure to work with Joshua. Always responsible and passionate about the work he does. Isn't afraid to ask questions and take responsibility. He's very motivated and ready to jump on tough tasks whenever the team needs it.

  • Dan McNamara - coworker at XPO Logistics

    Josh has extensive CSS expertise and was able to understand and resolve styling questions and concerns for myself and other coworkers quickly and effectively. He also tirelessly worked to improve the general CSS knowledge of the group as new advancements and techniques were developed.
