About

The author

Roughly thirty years in IT, across development, operations and infrastructure. Work spans applied cryptography, anonymity networks, embedded/LoRa systems, backend engineering and, more recently, biosignal processing (consumer EEG) and the calibration of machine forecasts. This laboratory is the trust surface where methods and results are documented — deliberately separate from any product.

• PGP: BB44 F320 653C 00B0 DC7A D0EE 7AE6 F93A D475 CB2B · public key
• Warrant canary: a statement signed with this key — renewed quarterly; a stale date, or a statement that disappears, is itself the message.

There is no contact form by design: a form is data processing and another documentation duty. Email or an encrypted message is enough.

Where this research runs

This notebook documents research, not products. Some of the directions are used in the products below — linked as evidence, not as claims:

• Ygoow — a metadata-resistant, account-less messenger: ygoow.com
• Sigelith — a public proof-of-existence log and time service: sigelith.org; open source: sigelith-desktop, sigelith-backup, sigelith-log, beat-key
• Laborbuch — the R&D record-keeping this site runs on: Laborbuch
