En ligne Hors ligne
I am a team leader, software architect and full-stack developer with 9 years of commercial experience including 6 years of full-time freelancing. My main skills include: ✓ Android apps ✓ iOS apps ✓ Deep learning and Google TensorFlow ✓ PHP/Python backends ✓ Amazon Web Services and complex server infrastructure administration ✓ Team leading multiple projects at the same time ✓ and much more I am not interested in small projects. For example I might not be able to build a Wordpress website much faster than other programmers. You can take full advantage of my skills when I work on very complex and big projects with multiple different technologies. This is where I can outperform other developers. I am mostly interested in 50USD/hr full time job offers.
