Antigenic / WorkFinancial infrastructure

From payment rails to the final record.

Four defined work packages for Fiscal Service and Treasury. Architecture, implementation, and transition into operations — with evidence for acceptance.

Work package / 01

Payment, settlement, and ledger systems

Defined work packages, typically 8–20 weeks

Discuss this scope

Engineering and delivery of the systems that move, settle, and record public money.

We design, build, and operate payment, settlement, and ledger-adjacent systems for Fiscal Service and Treasury. Architecture, integration, controls, evidence, and cutover are the work.

Artifacts produced

  • 01System architecture and integration design for payment and settlement flows
  • 02Ledger, reconciliation, and control-point implementation
  • 03Operational readiness, test evidence, and cutover plans

Work package / 02

Financial IT modernization

Phased programs, typically 12–26 weeks per increment

Discuss this scope

Cloud, zero-trust, and High Value Asset work with a named delivery owner.

We modernize financial IT where the Bureau of the Fiscal Service and adjacent Treasury programs already run — cloud migration, zero-trust architecture, and High Value Asset posture — with a named owner for scope, risk, and acceptance.

Artifacts produced

  • 01Target architecture and migration sequence for financial systems
  • 02Zero-trust and High Value Asset control mapping
  • 03Cutover, rollback, and operating-model transfer

Work package / 03

Financial-systems program recovery

Stabilization typically 6–12 weeks

Discuss this scope

A defined recovery package when a payments or financial-IT initiative is stalled.

Independent assessment, rebaseline, and a delivery cadence the program can hold. Scope, sequence, and acceptance criteria are reset; reporting is executive-ready.

Artifacts produced

  • 01Root-cause assessment and residual-risk register
  • 02Rebaseline of scope, sequence, and acceptance criteria
  • 03Stabilized delivery cadence with executive reporting

Work package / 04

Attested data, oracles, and integrity

Scoped increments, typically 8–16 weeks

Discuss this scope

Attested feeds, fraud and anomaly monitoring, and integrity controls on payment and settlement systems.

We build attested data feeds, provenance controls, and monitoring that sit next to payment and settlement systems. Governance is tied to financial controls, FISMA, and High Value Asset evidence.

Artifacts produced

  • 01Attested data-feed design and provenance controls
  • 02Fraud, anomaly, and monitoring instrumentation
  • 03Model and data governance tied to financial controls

Timelines are indicative. Scope, access, dependencies, and acceptance criteria are agreed for each engagement.

Transition into operations

A controlled cutover.
A continuous operation.

Define what must keep running, what proves readiness, and who authorizes the move. Engineer the return path before the transition.

The current system remains the operating path while the target is tested and reconciled. The authorized decision controls the transfer; unmet criteria trigger a hold or the agreed rollback procedure.

Sequence and acceptance criteria are defined for each program.

The next move

Bring us the system. Let’s define the work.

A payment rail to build. A financial system to modernize. A program to get moving. Start with the outcome you need.
