Work with me

Speaking, research and open-source support.

I work with banks, payment service providers, fintechs, regulators and industry bodies in three ways: talks on payments, post-quantum security and applied AI; research collaboration, from co-authoring a paper to reviewing a draft; and help for teams adopting my open-source ISO 20022 and post-quantum libraries.

These are personal activities, separate from my role at HSBC. The views I share are my own.

  • Speaking

    Keynotes, panels and expert comment on quantum-safe payments, ISO 20022 and agentic AI in banking. Every talk is available to book.

  • Research collaboration

    Co-authoring, draft review and working-group contributions, with the EPAA quantum-safe payments white paper as the reference.

    How research collaboration works

  • Open-source support

    Help adopting the ISO 20022 MCP suite and the post-quantum libraries: integration questions, issues and security reports.
