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

  1. Clarify the real need — I start by understanding the process and constraints before writing code. Clear requirements reduce rework.
  2. Build on the framework — Prefer native Frappe patterns, low-code where they fit, and custom code only where it adds lasting value.
  3. Leave it maintainable — Documentation, sensible naming, and fixtures so the system can be understood and extended later — including by you.
