Looking for…
…a stable, explainable and fully audit‑proof data chain?
I design and implement Single Source of Truth data models, subledger architectures and end‑to‑end regulatory data processes for:
- FINREP, COREP, DGS
- LCR, NSFR, ALMM
- IFRS (IAS 32/39/36/38/9), US GAAP
- ESG reporting, Liquidity monitoring, Basel frameworks
Result: traceable data flows, explainable reporting, audit‑ready documentation and regulator‑proof systems.
…remediation of failing processes, systems or third‑party data providers?
I deliver root‑cause analysis, recovery architecture, data validation, UAT and go‑live support.
- DGS audit remediation delivered with a 100% score
- SOC‑1/SOC‑2 re‑audit triggered at external providers
- Data quality recovery with Stater, Centric and other suppliers
…IFRS/US GAAP judgement that stands up to auditors and regulators?
I produce audit‑defensible technical memos and accounting positions for derivatives, structured notes, hedge accounting, impairment, consolidation and valuation.
…a senior who delivers high‑pressure implementations successfully?
I take ownership of requirements, solution design, modelling, UAT, documentation and go‑live.
Examples: IFRS 9, SAP/ACDOCA, mortgage onboarding, liquidity reporting, CRD IV / OneSumX implementations.
