Furthermore, I started working on AI in the last six years and worked on ChatBots and VoiceBots. - Have a perfect experience on NLP/NLU open source and cloud platforms like Google dialog flow and Microsoft Luis. - Create custom Modules of Freesiwtch and JANUS for Google, Amazon, IBM Speech To Text, and Text to Speech for real-time transcribers. - Create Conversational IVR and Voice Translator with the help of Google And Amazon. - Real-Time text-to-speech and speech-to-text with NLP/NLU. - Real-Time translator using Google. - good experience in Server Side audio processing and sending audio to any channel. - Excellent experience on Kaldi, Rasa(NLP, NLU), and Python Wavenet library to train models. ✅ Technical Skills : - Development: C/C++, Python - Opensource: TensorFlow, Rasa, WebRTC, reSIProcate - Technology: SIP, Audio/Video, NLP, NLU, Kaldi, deep speech(Mozilla). - Tools (Master): Wireshark, SIPp - Having enough experience with VoIP library for iOS, Android & Windows in C, and C++. - Having experience in VoIP clients and server development. ✅ Develop for all the platforms you need. We cover: - Web - iOS and Android phones and tablets Develop web apps that work on mobile browsers, e.g., video chats, audio and video calling, and audio-video SDK. We help to plan your product and develop it so that users love it. Work with companies and startups to create new products and improve existing ones. ✅ Have the right processes you know in advance. Ours: 1 - Sales managers are 1st level, software analysts. They clarify your needs. You get 3 results: what users can do - user stories, recommended technologies, and estimate based on previous projects. 2 - Analysts clarify details and draw wireframes. They are mockups of all the pages with clickable buttons. So you can play with your app before it’s developed and make changes for cheap. Based on wireframes, we calculate project time and price estimation. 3 - Designers draw clickable graphic design prototypes. 4 - A team of developers, test engineers, and a project manager develops the product. 5 - The team installs it on your server and helps with app store submission. We do maintenance - part-time work on minor improvements after launch. Write to discuss and estimate your project. We give user stories and recommend technologies for free after a call. Without a call, we can’t do it well, unfortunately. All the right questions in writing would have taken days and still much missed. Answer the same workday. On weekends we rest, but if you have a chance - respond too. So please write to us now :)

Having 12 years’ experience in Asterisk/OpenSips/Kamailio based application development. With over 6 plus years’ experience in WebRTC development along with 4 years’ experience in Windows development. Below are highlights of the projects and applications worked on: 1. Worked on all the Asterisk configuration changes, which even includes PJSIP. 2. Asterisk Event module (Which handles the request from NodeJS server and handles the events like play greeting, play MOH, Take input field, record greeting, making call, etc. it covers all the features and functionalities of asterisk) 3. Projects which deal with SIP WebRTC Client both Audio & Video. 4. JSON VOIP Client (Audio & Video).

Applications for Video conferencing on WebRTC, which supports Peer to Peer in browsers, Android & iOS systems. 6. Applications for Video on WebRTC with SFU (Janus GateWay) in browser, Android & iOS systems. 7. Windows and Mac-based Video Conference applications.
