Dear sir,
I am an android developer with 9+ years of professional experience in mobile and embedded systems, currently providing full-time freelance service.
I have understood your requirements and I can easily rehash the existing open source code to create 2 new apps as per your requirements. I will need a bit more details regarding IMEI protection.
Once requirements are finalized, I will deliver the prototypes within 2 days and provide the final version within next day after incorporating your review comments.
I will look forward to a positive reply.
Best regards,
Anamoy Sarma (Sam)
