We reviewed your requirements and think that we can help you with your mobile projects.
We have over 4 years experience with mobile applications, we build our own architecture, database-schemas and we have a complete backend solution to back it up. It depends on what type of project you require, but we have experience in more than the mobile technology.
We are a team of experienced developers with iOS and Android, mostly with communication protocols like XMPP and SIP. We have developed a few client-server apps with XMPP and eJabbered. All our applications include Multi-User Chat, sending online, idle and offline presence, sending location, files, photos and videos. We also work with mobile databases, message encryption at the highest level (2048 bit, private and public keys and openssl xmpp socket encryption).
We work on an hourly rate or rate/2 weeks. We still need more information about the application.
We have a demo ready.
