Explore our work01 / Selected work
Exchanges, protocol tooling, non-custodial markets and enterprise systems - the parts that have to work with real money, under real scrutiny. References on request.
Co-founded and engineered: a EUR/crypto exchange with three-tier KYC, cold-wallet custody with split keys and routed liquidity, live in 2019. Operated for two years and sold in 2021 to Stephen Gregory, a US compliance attorney who has since become CEO of Binance.US. Reference on request.
Embedded through Keyko AG, Zug: Filecoin Plus DataCap and notary tooling, and NEAR smart contracts in Rust. Ecosystem names only; no endorsement implied.
A non-custodial peer-to-peer marketplace for rare satoshis on Bitcoin: atomic settlement in a single PSBT transaction, and the platform never takes custody of funds.
A peer-to-peer lending platform being built with Swiss partners: identity-verified onboarding, CHF and EUR accounts and bank-to-ledger reconciliation. Details under NDA.
Filecoin and NEAR work was delivered through Keyko AG, Zug. Third-party names and marks remain the property of their respective owners; no endorsement is implied. Client references and further case detail are shared on request.
02 / Expertise
Contract systems on EVM and non-EVM chains: permissioned token standards, upgrade paths, freeze and recovery semantics, test suites written for the auditor before the audit.
Registries, mint and redemption flows, transfer restrictions, distributions and corporate actions modelled as explicit state machines with a reviewable history.
Role models, limits, allow-lists, attestations and multi-party approval - designed so an operator can prove who did what, when, under which policy.
Order flow, pricing, delivery-versus-payment settlement and daily reconciliation between chain state, bank and custody statements and the internal ledger.
Indexers, event pipelines, APIs, key management, monitoring and alerting that survive chain reorganisations, provider outages and external audits.
Onboarding journeys with identity verification, operator consoles, runbooks and incident tooling - so the system stays controllable long after launch.
System principles
Scoped roles and limits, multi-party approval for privileged actions, time-locked changes and a signed audit trail.
Deterministic indexers and a daily three-way reconciliation - chain, bank and custody statements, internal ledger - with break reports that name an owner.
Versioned contracts and schemas, migrations rehearsed on a fork of production data, and a governance path agreed before the first deployment.
Oracles, custody, identity providers and RPC nodes are wrapped with circuit breakers, fallbacks and a defined degraded mode.
Operator console, pause and resume semantics, runbooks, alerting and incident drills ship with version one.
Module boundaries per jurisdiction, partner and product line, so a new integration or rule change does not reopen the core.
