Fields of work

Five fields, one method: read the constraint, model it as data, make it executable, keep it auditable.

Depth
Written from build experience
Claims
Verifiable or marked to confirm

01 Field

Financial infrastructure

The components a transactional system needs before a product can exist on top of it.

  • Electronic money
  • Payment systems
  • Ledger architecture
  • Wallets
  • Reconciliation
  • Transaction systems

Electronic money

Electronic money is a claim on an issuer, not a balance in a database. The system has to know what was received, what was safeguarded, what was issued, what is held by whom, and what has been redeemed, at every moment and after the fact.

Payment infrastructure

Accounts, wallets, transaction rules, limits, holds, reversals, reconciliation and settlement. The interesting part is not the happy path; it is what the system does when a movement is partially complete.

02 Field

Regulation

Regulation read as a specification, not as a document to file after launch.

  • EME
  • ACPR
  • Compliance engineering
  • Regulatory reporting
  • Internal control

Compliance engineering

Controls, workflows, verifications, auditability and follow-up built as software, so that the evidence of a control is produced by the control itself rather than reconstructed later.

Regulatory reporting

One data structure, several projections. Reports become a query over the operating data rather than a manual assembly exercise.

03 Field

Artificial intelligence

AI put to work where the output has to be checkable by someone who did not write it.

  • LLMs
  • Agents
  • AI workflows
  • AI governance
  • EU AI Act
  • Automation

EU AI Act

Read as a system specification: scope, classification, documentation, human oversight, logging and traceability. The output is a design, not a policy document.

04 Field

Trust systems

Systems where the guarantee has to survive the operator, not depend on it.

  • Cryptography
  • Privacy
  • Digital identity
  • Electronic voting
  • Verifiability

Cryptography and privacy

Membership proofs, unlinkability and verifiability studied as primitives for systems where the operator must not be trusted with the correlation between an identity and an action.

05 Field

Digital platforms

Acquisition and distribution treated as engineering problems with measurable throughput.

  • Marketplaces
  • SEO at scale
  • Lead generation
  • Conversion systems
  • Automation
  • Demand generation

Digital platforms at scale

National information architecture, quote generation, qualification and matching. Acquisition treated as a system with throughput, loss and latency.
