Dear Sir,
I've got over 6 years of experience building highly customized ROM images on a number of hardware platforms, including TI OMAP(3,4)/Sitara SoC (ARM Cortex A8 CPU + PowerVR GPU + TMS320C64X DSP + peripherals) based projects, Android on existing phone hardwares (HTC One M9, M8 and Samsung S3, Note 3)
I've built industrial-purpose Android systems for house automation, OEM POS platforms, and a number of tiny UI changes - similar in nature to what you require - change of boot animation / boot splash, and configuration of the launcher images.
Best Regards,
Tomasz
