Selected work / 2026
Original products and systems I've built independently, directing coding agents from design through verification and release.
All 11 projectsFeatured system / Sentinel on Continuum
A clinical workspace on Continuum: a record foundation designed to span clouds and on-premises systems, with a path to keep working when primary systems fail.
Sentinel on Continuum: a workspace through an EMR outage.
A hospital data gateway with its own patient census and downtime order queue. Demonstrated through an outage, restart and verified replay.
Five simulated days of downtime, followed by verified message replay.

How I can help
Artilect US is my consulting practice. You work directly with me, with experienced colleagues available when a build needs a larger team.
Turn an early idea into a working system. I can take on the architecture and implementation, work through the unknowns, and carry the build into production.
Hands-on technical leadership for a team that needs a senior engineer or fractional CTO. I'll work with the team on delivery and the decisions behind it.
Review the architecture, investigate a delivery problem, or plan the next stage of a system your organization already depends on.
A little context
I'm Marcus Persson Rydberg, an engineer and two-time founder. I still like being close to the code.
I co-founded Luminare and spent a decade building clinical AI and public health systems for US health systems and government clients, where integrations and long-term operation were part of the job.
Earlier, I built government data infrastructure in Sweden through Artilect AB. My current independent work explores recoverable systems and what a small team can build with well-supervised AI agents.
