🌐 RAD Software Systems — International
Most developers can't read a trial balance.
Most accountants can't architect a database.
I do both.
ACCA/CAT qualified (2002). Full-stack engineer for 8+ years. I build financial systems where the accounting logic is correct by design — not corrected after the fact.

The Specialism
When the architecture has to be right
Financial software fails in predictable ways: data models that don't enforce double-entry, reporting layers bolted on top of operationally inconsistent data, payroll engines that miscalculate edge cases because the developer didn't understand the underlying tax logic.
These aren't bugs. They're design decisions made by engineers who didn't have the accounting knowledge to know what they were getting wrong.
I hold ACCA/CAT professional accounting qualifications and have built production financial systems from the ground up — general ledger, payroll, MIS reporting pipelines, trading operations tooling. The accounting discipline is in the schema, not the validation layer.
What I Build
Services
Financial Systems Engineering
General ledger, payroll, and accounting infrastructure built with double-entry enforcement at the database level. Period-locked, audit-trailed, GAAP/IFRS-aligned. Designed to survive an audit — not just pass one.
Trading & Operations Technology
Bespoke systems for trading operations, position tracking, and financial data processing. Built for correctness under load — where a rounding error is a reconciliation problem.
API & Integration Architecture
RESTful and GraphQL APIs designed with security-first principles. Third-party financial integrations — HMRC RTI, payment gateways, accounting platforms — built to the spec, not around it.
Management Information Systems
Structured reporting pipelines from operational databases to decision-ready output. Clean data architecture that eliminates the manual consolidation layer entirely.
