I build backends that don't hard-code the business. The rules live in configuration — formulas, field definitions, document templates — and the engine executes whatever the business defines.

I specialise in systems where non-engineers define the behaviour and the backend executes it: rating engines where the user authors the steps and the formulas, quote schemas where the fields themselves are configured, document pipelines where the templates and editable fields are owned by the business. That means designing for user-authored logic — validating it, versioning it, executing it safely, and making every result traceable back to the rule that produced it.

Selected Work
Most of this is client work under NDA, so there are no repos or live links to click. What I can do is walk you through the architecture, the trade-offs and what broke — in as much depth as you want.
Dynamic Rating Engine
The user defines the steps and the formulas. The backend executes them.
Dynamic Quote Schema
Quotes whose fields are configuration, not columns.
Document Generation Engine
Business-owned templates rendered to pixel-accurate PDFs.
Nexus Automation Pipeline
An n8n workflow that runs the delivery pipeline end to end.
Also shipped
Order Management System
Real-time microservices order tracking at scale.
Cosmic Event Calendar
Astronomy event tracker on the NASA open APIs.
