Builder, founder, and technology executive. Twenty-five years turning customers’ hard problems into products, platforms, and companies. Wearing all kinds of hats has given me a whole lot of perspective, and I’ve learned from enough of my failures to appreciate my successes. My best skill is working backward from real-world friction to solutions that move the needle, and building collaborative, high-performing teams to realize them.
Led the transformation of a successful software-services business into a strategic product-engineering organization built around customer outcomes, driving 35% year-over-year revenue growth in 2026. Managed a 350-person delivery organization across the US, Europe, Eastern Europe, Central Asia, and LATAM.
Built new product, design, and architecture practices, a new pricing structure, and an AI-native operating model; set the strategy and drove execution across delivery, talent, and go-to-market, with flagship initiatives at customers including Thermo Fisher Scientific, Johnson & Johnson, Roche, Dana-Farber, and BETA Technologies.
Spun out the software arm of Janeiro Digital into advanced data products for highly regulated environments. Phactor is a privacy-first federated network that queries data in place, matching global pharma with patients for clinical-trial recruitment and generating real-world evidence for medical-device submissions and post-market surveillance. XFORM is one of the first platforms to integrate enterprise systems with decentralized data and identity.
Notable customers: the NHS (XFORM), Novartis, and Novo Nordisk. Notable partners: RSA Security, Inrupt, Accenture, Deloitte, and KPMG.
Co-founded a professional-services firm specializing in massively scalable, data-intensive systems, and pioneered our RADD methodology for the precise delivery of mission-critical software. Grew it 100% organically from day one to a successful acquisition in 2021, with delivery teams across the US, LATAM, and Europe.
Work ranged from financial trading systems managing billions of dollars to a monitoring-and-diagnostics platform for the safe generation and distribution of power at the largest independent energy generator in the US. Named a Gartner Cool Vendor. Customers included Amazon, Caterpillar, IBM, UTC, and Vistra Energy.
First technology leader at Appex, an M&A-driven portfolio of 50+ consumer mobile apps and over 150M lifetime downloads — with apps featured by Apple, The New York Times, TechCrunch, Bloomberg, Yahoo News, Forbes, and The Washington Post. Designed and built the technology organization and a platform of reusable services (AI, payments, accounts, attribution, reporting, monitoring). As a member of the investment committee, I developed a data-driven diligence framework — working with our data team to automatically surface acquisition targets and project their performance to drive go/no-go decisions. I then partnered with product and marketing to integrate new acquisitions into the portfolio.
Author, contributor, and editor of open web standards for decentralized data and identity alongside Sir Tim Berners-Lee, inventor of the Web. Contributing author and editor of the core Solid Protocol, co-author and editor of the Application Interoperability and Shape Trees specifications, contributor to Solid-OIDC authentication, and creator of several reference implementations.
Application Interoperability and Shape Trees pioneered concepts now central to agentic data: fine-grained, consent-based access grants for agents operating on behalf of people and organizations, and self-describing data that lets agents discover and safely use it within the bounds of their grants.
Created a system for purchase and payment distribution of digital music — splitting and routing payments across rights holders in a networked marketplace. An early take on problems that decentralized commerce is still working on today. The work and team carried directly into Janeiro Digital.
Invented one of the first systems to detect sophisticated covert channels on enterprise networks (patented). [1] [2] Built and led an R&D team that included one of the creators of Kerberos, a co-founder of NetBSD, an astrophysicist, and some of the best hackers I knew. Customers included Bank of America, DuPont, Motorola, and AEP.
My first job in tech, started while I was still in high school — began in technical support and grew into a senior systems engineering role, responsible for systems and network security across a service-provider network. The problems I found here and the solutions I built to address them led to my first startup.
