My company can be the target for outsourcing of IT services for your company, so you can keep costs under control more easily and manage the project on more coarse-grained, higher level. I'm able to plan and build whole project from requirements gathering, system architecture, development, testing to deployment and further maintance. Can provide additional high quality graphic and ux design thanks to freeelancers cooperating with my company. My primary technologies are Django on backend and Adobe Flex (had some break from it) or Ember.js for rich frontend. I'm not tied to technology though, as I choose right tool to the right task. I learn eagerly and fast. Looking forward to cooperate with you. Regards, Mike
