$100 is sweet but $35 is what I charge.
Read on! I donot copy and paste.
I totally dig this setup, it's cutting edge, and it gives me a rush. I am savvy to all of these technologies, and I look forward to extensive exposure to MongoDB.
The project sounds interesting too. I've written a simple contacts app myself, to found out things could be done in much easier ways. Would be good to know a bit more about this one of yours.
For cross-platform phone apps I personally perfer Xamarin (C#) for better performance, PhoneGap always comes with a bit of latency.
Long story short: I am a serious professional, freelancing for the thrill and freedom. Consider me a pro working from home, not a usual "freelancer". I use C# / PHP a lot over the years, along with an array of languages / technologies. I am scrummer and I value communication, workflows and documentations just as much as techniques. I am strictly Object Oriented, although I'd love to get my hands dirty on functional programming.
Oh I am a native English speaker - yes I am also Chinese but that's how it is.
Hope this can work out,
Hackle
