Software engineering
for the web stack

Web sites, scripts, APIs and apps, Frappe/ERPNext instances. One person, careful craft, Australian based.

Practice

What I build

Custom business logic

Data processing, workflows, server and client scripts, and integrations that simplify how you actually work.

Frappe/ERPNext extensions

Tailored modules, reports, print formats, and process improvements on top of the standard Frappe/ERPNext foundation.

Reliable systems

Thoughtful data models, clear permissions, notifications, and operational tooling so a system remains usable as it grows.

Approach

How I work

01

Clarify the real need

I start by understanding the process and constraints before writing code. Clear requirements reduce rework.

02

Build on the framework

Prefer native Frappe patterns, low-code where they fit, and custom code only where it adds lasting value.

03

Leave it maintainable

Documentation, sensible naming, and fixtures so the system can be understood and extended later — including by you.
