Industry

Financial products where every step is on record. Audit trail, permissions and AI that holds.

Money, deals and contracts need a product where every decision can be traced. I lead the product and technology of FinTech and deal platforms, from the data model to the AI that assists the people using it.

  • Deal and M&A platforms
  • Audit history on every record
  • AI with permissions

The challenge

01

Customers want AI. Auditors want records. You need both on the same day.

Financial customers expect AI in onboarding, documents and support, and regulators expect to see who decided what. A product that delivers only one of these loses either the customer or the audit.

Questions

FAQ

Can you take over an AI-built or no-code FinTech app?

Yes. I moved a London founder's product off Lovable onto self-hosted Supabase, with tests and a deployment pipeline.

How do you handle audit requirements?

Every record keeps its history, every agent action is logged with its reason, and permissions are defined per role.

Do you help with due diligence?

Yes. I prepare the architecture, security and delivery answers that investors and acquirers ask for.
