I can solve your issues in these languages, improve your code, or realize a full project (website, smartphone application, software, video game ...)
The price depends on the time required by the tasks. 1 gig = 2 hours of work (I can do a lot in 2 hours!) , so there's no possible conflict if you add tasks later. I can work up to 5 hours a day.
I've been working on a lot of projects in different fields so I can use many languages and frameworks.
