Built to specification.

What each discipline can build. Scope is shaped to the operator, not the reverse.

Private AI & infrastructure
  • Custom agents inside your CRM, booking engine, or screener
  • Voice and email agents with tool calling into live systems
  • Private servers running local LLMs (30–70B) on sensitive data
  • Hosting and deployment to your VPS or on-prem — your servers, your data
  • Cross-tool orchestration on private rails
  • Model fine-tunes and internal-only registries
Software & interfaces
  • Custom applications and internal tools
  • Web platforms and client-facing interfaces
  • Customer and admin portals
  • Booking engines and payment flows
  • Technical SEO and search performance
Operations & automation
  • Customer support agents — voice and chat, multilingual, around the clock
  • Automated returns, refunds, and order changes
  • Review replies and inbox handling — drafted and sent
  • OTA reconciliation and dynamic pricing
  • Guest, lead, and client correspondence
  • Multi-property and multi-channel dashboards
Security & AI stress-testing
  • NFC, MIFARE, and RFID review of locks, keycards and authorisation
  • Wi-Fi, Bluetooth and RF assessment — rogue access points included
  • Hardware penetration testing
  • LLM stress-testing — prompt injection, data exfiltration, guardrail bypass

Letters of introduction.

An international upbringing and a degree in General Management from Boston College. A short professional sports career before the work turned technical.

Time inside the European Parliament, in the office of a Member. Coordinated high-level visits — among them the President of the European Commission and a national Prime Minister. Contributed to a successful re-election campaign.

These days the desk includes a seat at a European AI startup — production AI systems for customer operations, and the orchestration and integrations underneath. Quality assurance and account management across it: adversarial testing, failure analysis, and the quiet work of making sure an agent tells the truth under pressure.

Not every problem needs software. Not every system needs AI. The useful question is usually the same — what should be automated, what should remain human, and where leverage actually lives.
