About Me

Legacy reach. AI-native delivery.

Few architects can do both halves of the job. I have spent decades modernising the mainframe, DB2 and ERP estates that enterprise AI now has to reach, and I run an AI-native engineering practice: agentic coding tools, MCP and custom agent skills across the whole delivery cycle.

Why Hire Me?

Most AI specialists have never worked inside a core banking, insurance or ERP system. I have spent my career there, and I now build the AI that connects to it: governed, auditable and in production.

Key Strengths

  • AI in production: MCP servers, LLM document extraction, AI/BI over finance data
  • CTO since 2011, built and led a team of 50+ engineers
  • Deep legacy reach: z/OS, CICS, IMS, DB2, AS400
  • ERP and finance integration, including Sage Intacct
  • Employee of the Year at Sapiens UK, seven consecutive years

Recent AI work running in real systems

Vehicle finance · MotoData

MCP server for a finance platform

A Spring AI MCP server that exposes the platform's dealer and finance-application domain to LLMs as tools. The model provider can be switched between local (Ollama) and cloud (OpenAI).

Expense & document signing

LLM invoice extraction

LLM-based OCR and structured data capture built into expense-management and document-signing platforms, replacing manual capture of invoices and receipts.

Finance · Sage Intacct

Financial data hub with AI/BI

Scheduled Sage Intacct ingest with deletion sweeps, budget APIs and an AI/BI query endpoint. About 90 REST endpoints, supporting the move from a legacy ERP to Sage Intacct.

Engineering practice

Agent skills that encode standards

Reusable agent skills for Spring Boot APIs, Figma-to-Spring wiring, Intacct implementation and migration quality gates, so agents build to the house standard by default.
