I have 8+years embedded systems development experience and worked on various branches of the OpenWRT from Attitute Adjustment to Latest Chaos_calmer on Netgear and Linksys devices.
My relevant experience with OpenWRT is 2+ years, where I had undertook LuCI and UCI interface enhancements for various networking features.
In addition, I have 1.5+ years of development experience with Android (JB, KK, LL and Android-M) on almost all the layers from application to framework to JNI and native.
The specific requirement document is not yet visible to be here, but I hope it would not add any unexpected challenge in target platforms.
