Co-Founder of CaseMark #

CaseMark is an AI-powered legal workflow platform founded in June 2023 that helps law firms automate document review and create legal summaries. Their main focus is on helping legal professionals process large amounts of legal data more efficiently.

CaseMark specializes in AI-generated summaries for deposition transcripts, case summaries, medical chronologies and narratives, arbitration and trial summaries, and discovery responses. What traditionally took days or weeks—creating deposition summaries—can now be completed in minutes, allowing firms to generate multiple summary formats for a single deposition in an afternoon.

I have on occasion published blog posts through CaseMark.

3D Printed UAV design #

This was just a fun project that I built to share with with the community.

Modulus One is a modular FPV platform for endurance flights and automated missions. The wings are long and thin utilizing the S4310-II airfoil for fast and efficient flying.

• Modular and Customizable
• Easy to repair
• High Performance
• Long flight times

Monster Truck Jump Height Prototype #

I built hardware / firmware that used a cell modem and high resolution pressure sensor and 9 axis IMU to estimate jump height for realtime event display.

Paris Olympics #

Android app for heart rate tracking.

NBCU gave heart-rate monitors to parents of Olympic athletes to capture their reactions as they watched their children compete and shared it live on air. Test audiences had relished seeing parents' emotional responses while watching their children fulfill their sporting dreams, which prompted the broadcaster to implement the feature for the Games. The heart-rate monitors were among several new measures NBC introduced for their Paris coverage. Celebrities including Snoop Dogg, Peyton Manning, Kelly Clarkson, and Jimmy Fallon added their star power to the broadcast. All the action was also streamed in real-time on Peacock with interactive stats and athlete profiles.

DARPA SSITH Cyber Car Demonstrator #

We built a vehicle demonstrator for DARPA's SSITH program that shows how secure-by-design hardware can defend against cyberattacks on cars. The demo, which we built in my garage, uses a modified Smart ForTwo converted into a driving simulator that's now on display at the National Cryptologic Museum. It shows visitors how hackers can exploit vulnerabilities in a car's infotainment system—specifically through a buffer overflow in the over-the-air update service—to gain access to critical systems like brakes, steering, and acceleration, mirroring real-world attacks that have already been demonstrated.

The demonstrator is now housed in the National Cryptologic Museum.

DARPA SSITH Voting Demonstrator #

I was the technical lead on a voting system demonstrator for DARPA's SSITH program to showcase high-assurance secure hardware. The system used three secure RISC-V CPUs developed under SSITH—a microcontroller, desktop CPU, and server CPU—integrated into a complex system. We publicly red teamed it at DEF CON's Voting Village in 2019 and 2020, inviting white hat hackers to attack it over Ethernet, via serial devices, and most critically, by loading untrusted binaries directly onto the system to simulate attackers already inside. The SSITH secure hardware was designed to detect and defeat even this level of intrusion, proving that secure hardware can protect critical infrastructure like voting systems against known classes of hardware vulnerabilities.

LoStik - Long Range USB Device #

I designed the LoStik as an affordable, easy-to-use USB dongle that makes connecting to LoRa networks actually straightforward for IoT developers, network testers, and hobbyists. The hardware is built around Microchip's RN2903 (US) or RN2483 (EU) system-on-module, depending on your region, and I made sure it used a simple ASCII interface over serial so you can just plug it into any computer and start sending LoRa packets without dealing with a bunch of random programmers, serial adapters, and development boards. After using it in the field for months at Third Venture, I decided to open source the whole design and launch it on Crowd Supply so other developers could benefit from it.

The goal was to eliminate all the complexity that normally comes with setting up and testing LoRa/LoRaWAN networks. Whether you're connecting a Raspberry Pi to a gateway, building DIY home automation, or testing network coverage, LoStik handles it over USB and leaves your GPIO pins free for other stuff. It's breadboard-friendly, comes with Python examples, and has user-controllable LEDs for debugging. The whole thing is made in Portland and designed with the open-source hardware community in mind.

Canary Meshtastic Radio #

I designed the CanaryOne from the ground up as a ruggedized, ready-to-go Meshtastic radio for tactical off-grid communications. I handled everything from the hardware design and board layout using the nRF52840 MCU and SX1262 LoRa transceiver, to the firmware configuration that ships with Meshtastic 2.3.13 pre-flashed, to the case design that keeps it tough enough for field use while maintaining easy access to the USB-C port and SMA antenna connection.

The whole thing was built with the goal of having it work out of the box—just power it on, pair via Bluetooth, and you're meshing with AES256 encryption. I sourced all the active components from NATO countries and designed it to run 24-72 hours on a single charge depending on how hard you're pushing it, and the GPS module means you get location tracking even when you're running it as a standalone node.

Makers at Work #

Makers at Work is about the tinkerers, hackers, and inventors reinventing the world one project at a time. These creative folks use everything from laser cutters to Arduino boards to build cool stuff. Through 21 interviews, you'll meet people like:

• Jeri Ellsworth, who teaches magnetic logic and installs roll bars on stock cars
• Eben Upton, creator of the Raspberry Pi
• Becky Stern, who adds LEDs and sensors to clothing
• bunnie Huang, Shenzhen electronics market expert

What makers have in common: they respect the past but hate convention. If they can't invent something new, why bother? You'll discover:

• Tools driving the new industrial revolution
• How to turn weekend projects into businesses
• Using crowdfunding to make ideas real
• How open-source tech is lowering barriers for inventors

Airship #

I co-founded Urban Airship back in 2009 with the goal of helping companies engage with their mobile users through push notifications, SMS, and personalized messaging. We built the platform to not only deliver messages across multiple channels but also give businesses the analytics they needed to actually understand their customers' behavior. Over the years, we raised over $90 million from investors like Intel, Verizon, and Salesforce, and made some strategic acquisitions along the way—SimpleGeo for location services, Tello for Apple Passbook tools, Apptimize for user experience testing, and ReplyBuy to add SMS commerce capabilities.

In 2019, we rebranded to just "Airship" to reflect how much we'd evolved beyond push notifications into a full mobile customer engagement platform. Today the company operates globally with offices in nine cities, and it's been incredible to see it grow from a Portland startup into a major player in the mobile marketing space.

Afghanistan #

I spent 6 years in the Oklahoma National guard including 9 months in Afghanistan where we trained the Afghan national army and took on community projects like passing out school supplies.
