Expertise in programming and R&D in WebRTC, SIP, VoIP and RTP media streams. Master’s graduation Dec 2022.
Work Experience Netflix Streaming Open Connect Transport protocol R&D intern (2022) Did research and development on the algorithm for Netflix's new upcoming highly-interactive RTP/RTCP based streaming media applications. Analyzed and leveraged heuristics for rate adaptation, bandwidth and latency estimation, congestion control and loss recovery of RTP/UDP media streams. WebRTC.ventures intern (2022) I implemented WebRTC Telephony applications using SFU, MCU and hybrid setups. Janus, Freeswitch. I implemented the optimization of metrics for TURN and ICE. Airtel IQ Core Lead engineer for cloud telephony (2020) I designed and implemented the critical piece of VoIP backend system on Asterisk libraries. I led and delivered the Cloud telephony for Airtel via SIP trunking. Plivo Zentrunk SIP trunking and cloud Telephony (2018-20) I designed the SIP trunk service architecture for Plivo Zentrunk. I was single owner for crucial optimizations of programming and product shaping of core SIP backend platform. I owned Inbound call flows, Security, Call-Insights, Hangup Code, CDR, MOS analytics, Media route optimization, handover leveraging PoP as part of leading this project. IPC Unigy 360 Soft turret for financial communications (2016-18) On-contract via Tech Mahindra to implement Software based VoIP turret phone system. I designed and implemented the full stack distributed CPaaS from inception to delivery. Implemented the integration to Genband Spidr gateway and Radisys Media Server. Jiyo Now, Streaming and Broadcasting Solution (2014-16) Programmed modules for Wowza engine, CloudFront distribution, adaptive streams for HLS, RTSP, RTMP, transcoder pipelines. Researched and innovated Media engine for WebRTC to legacy codecs. Patented service for multimedia conference systems. Build broadcasting service jiyoNow and UCC(Unified Communication Collaboration) TangoFX. Telecom practices Lab (2011-14) Conceptualization and implementation of “Telecom Service Orchestration and Transformation Engine” for Elisa(Belgium) among a few others. Designed call flow and architecture for interaction of IMS SIP Servlets with existing telecom applications via IN-SIP, SIP-SIP and SIP-Web RhinoTAS and Mobicents.
