About Jonathan “Jon” Holman

I'm Jonathan Holman — most people call me Jon. I'm a principal engineer and founder based in Rochester, Minnesota. My current public work centers on CoreFeld, AI, security, cloud, and federal health systems.

What I do now

I founded CoreFeld, a Minnesota-based technology consulting company started in 2026. I work through CoreFeld as a principal engineer for AI, security, cloud, platform, and federal health engagements, including corp-to-corp subcontracting and direct consulting.

I also run QuorumPeak, a remote-first, equity-free, fee-free incubator for early-stage AI, cloud, and software startups based in Rochester, MN. I keep it small enough for direct senior engineering attention.

On the side, I build and publish free, ad-free versions of classic casual games for iOS and Android under my legal name, Jonathan Holman — no ads, no in-app purchases, no tracking.

Where I come from

CoreFeld and the rest of my founder work stand on 24 years of shipping software. I studied at Towson University and spent my engineering career across cloud platforms, web systems, automation, accessibility, security, and large-scale public-sector delivery. That includes a decade across CMS programs — Office of Communications, QPP, MACPRO, and MDCT — most recently as a Principal Engineer at Stratiform Digital supporting federal health applications on AWS with DevSecOps and infrastructure automation, and before that leading cloud practice and modernization work at Groundswell.

How to reach me

LinkedIn is the primary public profile and the best way to connect. I'm open to principal engineering and architecture roles, remote or in Rochester, MN. Consulting and subcontracting inquiries can also go through CoreFeld. Code lives on GitHub.
