About Me

I've been working as a software engineer for over twenty years, specializing in highly scalable web services and applications. I'm especially interested in blockchain technology and smart contracts, and am currently running a consultancy in this area. In addition to my work, I'm passionate about philosophy, transhumanism and the performing arts.

Mainframe, an expert in real-time workplace messaging, is launching the first fully decentralized messaging platform. A proof of concept is already available based on the Ethereum blockchain and additional innovations will soon follow. I'm excited to be leading the engineering team in this new phase of our development. I'll be working for them remotely from Provo, UT, eventually helping to build up a presence here.

Divvy has partnered with card issuers to revolutionize corporate expense management. Instead of collecting receipts after employees spend money, Divvy issues cards, both physical and virtual, in a handy mobile app. The spending constraints on these cards are closely controlled, and receipts are generated automatically from real-time transaction data. The company just launched. I hired and built the engineering team from scratch, and was heavily involved in developing the core product.

The World Table's tools and algorithms enrich online interactions by embedding consensus-based virtue metrics into the web, for individuals, organizations, devices, web locations and more, in a robust and decentralized manner. I directed and helped to build the company's flagship product (a comment plugin with community moderating capabilities) from inception to launch, deciding on the technology stack, setting up automated deployment and testing, issue tracking, and designing the frontend and backend to be Internet-scalable. This project was written primarily in ES5 Javascript using the Google Polymer web component framework and Firebase for real-time data persistence. We also founded the Open Reputation project for blockchain-based reputation solutions.

At Cisco I helped to build a set of web services and web UIs for managing large-scale advanced testing scenarios of Cisco Telepresence endpoints and infrastructure products. In addition to an opportunity to sharpen my technical skills, the nearly five years that I spent abroad in Norway and England were invaluable opportunities to be exposed to different languages, cultures, and different ways of managing projects and doing business.

Confreaks specializes in recording conferences, seminars and workshops, and in providing networking and other technical services to conferences. Our debut event was the recording of MountainWest RubyConf 2007, and we went on to record a number of other conferences, many of which helped to strengthen the Ruby and Agile communities. We developed a unique method for recording and preparing our footage that takes advantage of our programming skills to do things more efficiently than conventional video production companies. I sold my share in the company in December of 2009 when I moved to Norway.
