01 · Track record
Eighteen years inside HR information systems: the first years in payroll production, the rest in consulting. Since going independent I work as a senior consultant for large groups, currently on the SuccessFactors programme of LVMH, on core HR data, multi-country rollouts and the parts of a programme nobody wants to own.
02 · Platforms
SAP SuccessFactors Employee Central, Oracle HCM Cloud, PeopleSoft. Core HR design and configuration, migration off legacy payroll and HR systems, integration with downstream tools, and the specification work that keeps a shared multi-entity model coherent.
03 · Software & applied AI
I also build. I designed, developed and shipped a complete SaaS application alone: Next.js, PostgreSQL, Cloud Run, generative AI, eight languages, from schema to production. So I can specify an integration and then write it, and judge where generative AI earns its place in an HR process and where it does not.
04 · Data governance
Much of the work is unglamorous: duplicate identities, ownership of reference data, rules that still hold when twenty entities share one instance. I treat HR data as a system with owners and consequences, not as a by-product of reporting.
