Work
One system I built and run, and five projects across revenue management, customer analytics, healthcare, data engineering and applied AI.
Flagship project
A system for B2B lead discovery, prioritisation and sales decision support, built on PostgreSQL, Supabase, PostGIS and n8n.

Hotels lose revenue to last-minute cancellations, but overbooking blind gets guests walked. Predict each reservation, then price the two errors against each other.
$10,620
Additional modelled profit from moving the decision threshold to 0.55. A simulated result on a public dataset, not realised revenue.

Customer Analytics × Predictive Modeling
In a multi-SIM market, a silent customer may be switching handsets or may already be gone. The operator needs to tell those apart before revenue drops.
Built as an early-warning problem rather than a scoring exercise: the model was selected on its ability to catch customers before they go silent.

Healthcare Analytics × Power BI × Decision Support
Pneumonia is predictable to the week and preventable by known means. The question is whether the health system is positioned before the peak arrives.
9 weeks
Mobilisation window before the regional influenza signal peaks in week 7.

Data Processing × Databases × Knowledge Graphs
Skill demand is scattered across job boards, occupational standards and macro indicators. No single source tells a student what to learn or where to go.

Agentic AI × NLP × Evidence Validation
ERP documentation fails in one direction: it asserts controls the configured system does not enforce. The agent has to refuse to write those claims.
19 rules
Deterministic validator between the model and the document. Claims resolve to evidence or go unpublished.
