Author of the book “ WebRTC Integrator's Guide“ by Packt Publishing

Frequent tech blogger and contributor to forums and communities , have many white papers and conference presentations to my credit including an IEEE paper on Hybrid micro Grid .

Patent - “Multimedia Conferencing“ US patent - US20180284957A1

Speaker at many tech conferences/meetups (Jquery Conf , GraceHopper , kranky Geek , Hackaday , Barcamp , blockchain summit , plivo Tech conference etc) and won many hackathons. Jury member for smart india Hackathon.

Working on my second book titled “Innovations in Voice Over IP and its practical applications”

Work Exp

Currently leading VoIP core team at airtelIQ and former core voice engineer at Plivo

Much before that I was the core developers at IPC’s cloud trading communication platform , integrated to Oracle SIP application server back end with genband gateway , radisys media server and apache tools .

Also core developer for Jiyo (https://www.jiyo.com) for b2b unified communication , media streaming and API platform development .

Part of innovation and R&D telecom labs, also worked with the Converged network systems Lab in Tata consultancy services on many next-gen SIP applications for world’s top telecom providers which includes British Telecom , ATnT , Bouygues telecom, Belgacom among others . I have long working experience on WebRTC APIs and have made 2 full fledged VOIP communication platforms ( one using SIP as signalling , another using socket signalling ) . I have hands-on experience in developing Enterprise logic for the telecom application server in SIP and JAINSLEE using Core and Enterprise Java .
