Things I've built

SannadHealth, an AI clinical scribe

Listens to a doctor and patient and drafts the clinical note, ICD-10 codes and follow-ups during the appointment, not after it. I owned the five-agent architecture; the coding agent can only pick from a retrieved ICD-10 shortlist, so it can't invent codes.

Enterprise SOC Home Lab

A multi-VLAN SOC lab on Proxmox VE, segmented into five zones: attacker, DMZ, internal, management and Splunk. pfSense and Suricata IDS/IPS feed centralised logging in Splunk; now wiring Splunk to n8n agents that investigate logs and raise alerts on their own.

STAM, a security tool asset manager

An on-prem, multi-tenant platform that gives a managed service provider one auditable record of every security tool across its clients: what's deployed, on which assets, under which licence, and where coverage is missing. Every change ties to a ticket and the audit trail is append-only.

DGM Platform, a self-evolving AI system

LLM-driven optimisation of code and prompts. The security work is the sandbox for untrusted generated code: network-isolated containers, CPU and memory limits, read-only inputs, no shell execution and sanitised output.
