Senior iOS developer specializing in real-time messaging and VoIP solutions.
IndiaWhat I'm looking for
I am a results-oriented Senior iOS Developer with eight years of experience building complex messaging applications and real-time communication systems. I architect and deliver enterprise-grade iOS solutions end-to-end, from requirement analysis and architectural design to deployment and App Store submission.
I built a custom XMPP framework, implemented Google WebRTC-based voice and video calling, and migrated legacy SIP infrastructure to Linphone to ensure stable background calling. I engineered WhatsApp-like chat features, secure messaging with API encryption, efficient local storage with SQLite, and rich media handling and notification service extensions.
I thrive on solving hard technical challenges—particularly around VoIP background execution and custom protocol design—and I seek roles where I can leverage deep expertise in native iOS frameworks (CallKit, PushKit, AVFoundation) and real-time signaling to build scalable, high-performance mobile products.
