I worked with Joshua at Freelancer.com. Joshua was an absolute out-performer in my team. He has deep expertise in Android app development and is also a great team player who can support his teammates to achieve business goals. I would love to recommend Joshua to any team that needs a technical leader.

Mike Ni Senior Manager of Products, Atlassian

I worked with Josh on a few projects, and he's one of those engineers that just has the knack for getting things done. It's also amazing how he always managed to remain level-headed, despite being put under tremendous pressure. If someone were to ask me to form an A-team that requires a mobile engineer, Josh would be at the very top of my wishlist.
