Contact

Email is the reliable channel and reaches me directly. Everything below is a verified account — if an approach claiming to be me arrives anywhere else, treat it with suspicion.

Direct

Email
[email protected] — the best way to reach me. I read everything and reply to anything that is clearly addressed to me and not automated outreach.
PGP
My public key is published on Keybase, which also carries a signed proof tying that key to this domain. Use it for anything sensitive, including vulnerability reports.

What to reach out about

  • Decentralized identity and verifiable credential work — issuance, wallets, verification, interoperability, or an mDoc/OID4VC integration that is not behaving.
  • Collaboration on EU-funded or applied research projects that need a working reference implementation rather than a report.
  • Protocol or smart-contract engagements in the DeFi and reputation space, including reviews of an existing design.
  • Security disclosures affecting anything I maintain. Use PGP, and expect an acknowledgement before a fix.
  • Speaking, teaching, or mentoring on identity standards and Web3 engineering.

Please do not

  • Send unsolicited recruitment or agency outreach that has clearly not read this page.
  • Pitch token launches, liquidity schemes, or paid promotion. I do not take them.
  • Ask for backlinks, guest posts, or SEO placements on this site.

Where I am

Maribor, Slovenia (Central European Time). I work across European time zones and can usually overlap with the US East Coast in my afternoon.
