Things we built
I've been fortunate to work with amazing teams of people. Everything on this page was built together — with talented engineers, designers, product people, and leaders. I'm writing it down before it all disappears into the ether.
The AI foundation company for healthcare. We build AI solutions that automate the care journey for patients and clinicians and accelerate pharmaceutical trials.
Ava
Our first AI-powered patient engagement product — using machine learning to engage patients in dynamic conversations through text, voice, and video, surfacing insights to their care team in real time.
Sidekick
AI-powered notetaking that generates detailed clinical documentation from provider sessions automatically. Saves providers approximately 88% of their documentation time — giving them hours back for actual patient care.
A direct healthcare company built to remove the middlemen from healthcare delivery — connecting patients directly with care through technology and infrastructure, no brokers, no unnecessary complexity.
Led the R&D team through the company's rapid growth and successful acquisition by the Carlyle Group. Built and managed a 100+ person organization. Led the company's shift into machine learning-powered hiring tools.
HireVue Video Interviewing Platform
The flagship product — AI-powered video interviewing used by hundreds of the world's largest companies and millions of candidates. We rebuilt the platform for global scale and reliability on AWS, supporting both live and on-demand interview workflows with structured evaluation and AI-assisted insights.
AI-Powered Assessments
We built the ML models that analyzed video interviews to help predict candidate performance — processing thousands of data points per interview. This was cutting-edge and controversial work. We took the ethical dimensions seriously, building bias detection (patented) and adverse impact correction directly into the system.
CodeVue
A coding assessment platform with 200+ challenges across Python, Java, Ruby, JavaScript, PHP, C++ and more. Combined coding exercises with video interviews so you could evaluate how someone thinks, not just whether they can pass a test. Included code playback to review the candidate's actual problem-solving process.
HireVue Coach
A training and development tool that used video and predictive analytics to help sales teams improve. Reps would record practice pitches and get AI-driven feedback on their delivery, product knowledge, and customer engagement.
Sorenson Communications
The leading provider of Video Relay Services to the Deaf and hard-of-hearing community. We shipped 5 products across multiple platforms — all on time or ahead of schedule. This was technology that made a direct, daily difference in people's ability to communicate.
ntouch PC
Turned any PC with a webcam into a full-featured Sorenson videophone. Users could make Video Relay Service calls, voice carry-over calls, and point-to-point calls right from their computer — no special hardware needed.
ntouch Mobile
Sorenson's first mobile apps for iOS and Android — bringing Video Relay Service to smartphones for the first time. This was huge for the Deaf community. Suddenly you could make a relay call from anywhere, not just from home.
Mobile CaptionCall
Real-time captions for phone calls on mobile devices. Built for people with hearing loss who could still use some voice but needed captions to follow along. Free to qualifying users through the federal program.
BuzzCards
A simple, clever app for communicating with people who don't know sign language. Like a deck of flashcards — type a message, show it to the person you're talking to. You could create and store cards ahead of time or make them on the fly. Launched on iOS and Android.
Pepun
Streaming and monetization platform for premium content and pay-per-view subscribers, primarily focused on the Latin American market. Defined the business and technology strategy, built the backend for content management, payment, and reporting, and worked with investors to create an international joint venture.
Move Networks
We built the world's leading HD video streaming platform for premium content — and along the way, helped invent adaptive bitrate streaming (ABR), the foundational technology behind how Netflix, YouTube, and every modern streaming service delivers video today. Built the team from 8 to 55 engineers.
Move Player
This was the product that blew people's minds. HD video streaming in a web browser — in 2007. The player powered Fox.com, ABC.com, ESPN360, NFL, CW, Televisa, and ProSieben. We set the record for the most simultaneous streaming viewers on the internet. We partnered with Microsoft to live-stream the Democratic National Convention in HD via Silverlight. By 2008 we were streaming 60% of the most popular TV shows online — 55 million unique viewers watching over 100 million hours of HD content in a single year.
Adaptive Bitrate Streaming
The core innovation: automatically adjusting video quality in real-time based on available bandwidth. This solved the fundamental problem of streaming HD video over unpredictable internet connections. The patent was awarded in 2010, and the technique became the foundation for streaming technology adopted by nearly every major video provider worldwide.
World Wide Packets
Carrier-grade Ethernet platforms — the infrastructure that let telecom carriers deliver voice, video, and data over a single network. We shipped over 70,000 units to 100+ customers in 25 countries. I served as a voting member of the IEEE 802.1 standards committee for 5 years.
LightningEdge LE-311v
The product I'm most proud of from the WWP years. A 24-port carrier-grade Ethernet service delivery switch that could handle everything from residential triple-play to business Ethernet services. Rock-solid reliability in a 1U form factor. Deployed across major carrier networks worldwide.
LightningEdge LE-3300
The big aggregation switch — sat at the center of carrier networks tying together all the access devices. We called it the LE-4400 internally during development; it shipped as the LE-3300. This was the backbone of the product line, connecting all the edge access devices into a unified carrier network.
LightningEdge LE-210
The small-form-factor residential access device — the box that went into buildings and homes to deliver Ethernet-based services. Part of the full family that included the LE-310 and other access models, deployed everywhere from apartment buildings to enterprise branch offices.
The full LightningEdge family
A complete product line from small access portals to large modular switches. Deployed at scale by AT&T, Virgin Media (NTL/Telewest), KPN, Comcast, and Clearwire. OEM partnerships with Lucent, Ericsson, and Tellabs. These were the boxes that brought Ethernet-everywhere to major carrier networks.
Oresis Communications
A softswitch startup building the future of telephony. We shipped a beta unit to Williams Communications before the telecom crash took the company down in 2002.
ISIS-700
A multiservice switch designed to replace the old Class 4 Tandem telephony switches — enabling carriers to migrate from separate circuit-switched and packet-switched networks to a single unified backbone for data, voice, and video. I led the team building the infrastructure layer: internal event system, alarm management, logging, and diagnostics. (Yes, the name has aged poorly.)
IBM
Where I learned what great engineering looks like at scale. Worked on networking products and helped lead IBM's transition from Token Ring to Ethernet. Participated as a voting member of the IEEE 802.3 standards committee.
IBM 8271 EtherStreamer Switch
The product that marked IBM's move into Ethernet switching. Started as an 8-port 10Base-T switch and evolved through multiple generations — the Model 108 with enhanced management, and the Nways models (524, 612, 624, 712) with 10/100 auto-sensing and Fast Ethernet/ATM backbone options.
IBM Nways 8210 Managed Stackable Hub
A managed stackable Ethernet switch that brought IBM's enterprise management capabilities to workgroup-level networking. This was the product I spent the most time on at IBM — where I really learned the craft of building production networking software.
Link Aggregation (IEEE 802.3ad)
Drove Link Aggregation technology across multiple IBM product lines and participated in the IEEE 802.3 committee that developed it into the 802.3ad standard. Also created simulation and unit testing tools that let developers write 99% of their code without dedicated hardware.
Velocity Soft
NewMonic
My first company, founded when I was seventeen. NewMonic was a terminate-and-stay-resident (TSR) program that intercepted keystrokes for spelling correction, stenography, and basic language translation. Where it all started.
