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.

Email: [email protected] — the best way to reach me.
PGP: Public key on Keybase, with a signed proof tying it 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, or an mDoc/OID4VC integration that is not behaving.
Applied research projects that need a working reference implementation rather than a report.
Protocol or smart-contract engagements, including reviews of an existing design.
Security disclosures affecting anything I maintain. Use PGP.

Not interested in unsolicited recruitment, token-launch pitches, paid promotion, or SEO placements.

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