Blockchain Solution Architect
Engineering Lead
I architect, build, and lead production blockchain solutions — from trust boundaries and signing flows to infrastructure, deployment, and the engineering that ships them.
I still write. Solidity, TypeScript, and Rust stay at the center.
At TEKHQS I lead engineering on RYT — chain and wallet — and deliver Canton Network engineering for an RWA platform. Client names stay off this site.
Current flagshipCanton RWA infrastructure — isolated wallet origin, threshold signing, attested remote signer.
01 / What I build
Canton RWA infrastructure, wallet and custody systems, protocol engineering, then inspectable production work. Canton is a flagship — not the whole record.
02 / How I think
Trust boundaries. Signing. Authorization. Infrastructure. Settlement.
01
Where keys live. Who can request a signature.
02
The payload is pinned before anyone signs.
03
Policy before the signing boundary.
04
Threshold, attested, never a hot-wallet story.
05
Submit only after integrity holds.
03 / Proof
Years in the work. Engineers led. Production systems shipped. Tokens vested on-chain.
04 / Selected work
Three current systems. Canton first. Then wallet and protocol work. Public Ferrum systems stay on the work index.
