Hi, I’m a London based software engineer with more than 10 years of experience working on enterprise level applications builded with Python, Java and PHP.
I can guarantee highest code quality (best design patterns, libraries and framework) which makes my solution easy to maintain and extend with highest performance.
That looks like really interesting project, and I will be happy to do it for you, but to propose final price and time needed for it I need to know few more details.
If you have any questions feel free to contact with me.
