About

I'm a solution architect and hands-on engineer. For twelve years I've built enterprise integrations and automation, usually from inside the customer's environment — from first discovery call through to the system running in production.

My current work is applied AI: multi-agent systems, MCP servers, RAG pipelines and LLM-driven workflows, built on Vertex AI and the Claude and OpenAI APIs. I write Python and TypeScript daily.

Senior Solution Architect

Rossum — AI document processing for enterprise finance teams

  • Led a six-month global rollout of AI invoice automation for a Fortune 500 semiconductor manufacturer across EMEA, APAC and the Americas, cutting per-invoice processing from minutes to under 60 seconds.
  • Built Python/FastAPI microservices that move extraction output into Coupa, NetSuite and SAP over REST, OAuth2 and webhooks, with idempotent processing, retry logic and dead-letter queues.
  • Designed three-way match validation, duplicate detection and tax rules across 15+ jurisdictions, reducing manual AP rework by around 40%.
  • Work embedded with customer IT and finance teams from discovery through UAT and hypercare.
