r.Rahul Kumar LohraANDROID PLATFORM ENGINEER

Staff-level Android Platform Engineer

Reliable platforms.
Stronger engineering teams.

I’m Rahul Kumar Lohra, an Android platform engineer with over a decade of experience building mobile foundations, SDKs, and developer tools.

At GetStream.io, I work on the Android Video SDK and WebRTC: making calls more resilient to changing networks, improving audio routing, and evolving the architecture behind real-time communication.

Previously, I led Android architecture and infrastructure work at TikTok and held principal engineering roles at Tokopedia and Green Agrevolution. My work spans reusable platform components, performance profiling, developer tooling, and engineering standards that teams can adopt with confidence.

I enjoy turning ambiguous platform problems into clear architecture, practical diagnostics, and safer migrations. That same curiosity drives my open-source work, technical writing, and interest in retrieval-augmented generation.

    Senior Engineer · Video SDK & WebRTC

    Building a more reliable Android Video SDK, from WebRTC reconnection and incoming calls to audio routing and core SDK architecture.

    • Architected a two-tier WebRTC reconnection strategy using existing ICE connectivity and full ICE re-establishment, informed by Android network changes and WebSocket health.
    • Reworked incoming-call ringing with polling fallback and ringing-attempt management to handle WebSocket disconnections.
    • Improved Android Telecom and Bluetooth audio integration, addressing concurrency, audio routing, permissions, and call-state consistency.
    • Modernized call management, camera lifecycle, authentication, and notification pipelines in the Android Video SDK.
