A conversational and generative AI company. He was responsible for all technical aspects of the solution, including the development of a unique multimedia gateway that integrated speech recognition (ASR), natural language processing (NLP), and real-time audio and video. The gateway interfaced with customers via SIP / WebRTC and was capable of supporting full-duplex conversation communications, including handling interruptions.Vocinity was a platform that offered end-to-end contactless, conversational voice and video bot services. It replaces traditional enterprise technology, manual data capture processes, and long hold times with interactions that are similar to "Alexa" or "Siri." The platform delivered more economical, contextual, rich-media, voice-based engagements to enterprises in the healthcare, retail, hospitality, and financial services sectors. Customers access Vocinity’s scalable and secure solution via phone systems, websites, mobile applications, digital signage, and QR codes.Furthermore, Nathan developed deep learning models to remove background noise, voice activity detection, gender identification, and speaker diarization. He also played a major role in creating advanced language transformer models that significantly improved ASR accuracy and reduced word error rates.Nathan was also responsible for creating and maintaining the Vocinity private data center. The center consisted of three racks with 21 physical servers, each with NVIDIA GPUs. The architecture utilized virtualization and containers to support a microservice architecture. Three core routers established a direct peering connection with Google and Azure, enabling the creation of a hybrid cloud that facilitates on-demand scaling into 3rd party clouds based on the required capacity.

I joined BroadSoft as part of the acquisition of my previous company Exario Networks. As VP Technology at BroadSoft, I was primarily responsible for driving innovation. I shepherd the video conferencing and WebRTC platforms, helped identify and vet acquisition targets, and participated in high-level corporate strategy. I helped lead the transition to the cloud leveraging GCP and AWS to allow products to auto scale over a global geographic deployment. As the technical leadership of BroadSoft Labs, I oversaw the internal ideation, proof of concept, and then eventual productization. Two products I am most proud of are Hub and Voice Assistant. Hub brings together email, contacts, documents, storage and more giving you easy access to the most frequently used actions. Hub is a platform that consumed services via 3rd party APIs and provides a rich set of APIs to others allowing customers to create their own applications. The real power of Hub is its ability to provide contextual information for the people you are communicating with. If you're chatting with Bob as an example, it will bring up past emails, documents, etc that you have shared with Bob. Voice Assistant is a business personal assistant that integrates into your communications client as well as your business applications. You can ask questions like "What does my day look like" and get an overview of meetings and tasks for that day. Or you could say "I am going into a meeting please hold all my calls" and the system would enable your do not disturb feature and automatically remove it after the meeting is over based on your calendar. It's important to note that while Voice Assistant does leverage Google for Speech to Text and Amazon for Text to Speech, all of the Natural Language Processing and Machine Learning is done locally and does not rely on any 3rd party platform.
