Sites and projects I’ve built to fill knowledge gaps I kept running into.

• datacentricsecurity.org — Concepts, hands-on labs, reference architectures, and operational scenarios for implementing data-centric security on AWS, covering NATO standards and coalition data sharing.

• xdomainsolutions.org — A vendor-neutral guide to cross-domain solutions: what they are, how they work (protocol break, treatments, security enforcement), and the three types of CDS.

• louqr.com — A privacy-focused, client-side QR code generator with logo embedding. All processing happens in the browser, no data sent to any server.
