Simple POS System
In progressA lightweight point-of-sale web app for small shops — product catalog, cart, checkout, and a basic daily sales summary. Built as a way to learn full-stack web development from scratch.
IT Systems & Infrastructure — with a growing side of code
I keep systems running.
Lately, I'm learning to
build the software too.
By day I handle IT infrastructure, procurement, and security for a manufacturing estate. Outside of that, I'm teaching myself web and IoT development — starting small, with a point-of-sale app and a home-grown IoT project, both below.

About
A bit about how I got here
I started out in CRM and teaching before moving into IT — first hands-on with networks and infrastructure, then increasingly curious about the software side of things. These days most of my work is systems administration and IT procurement, but my evenings go toward learning to build actual applications: a simple point-of-sale system, and a small IoT project connecting hardware to a web dashboard.
This site is partly a record of that — a place to put the things I build once they're further along, not just the job titles behind me.
Projects
What I'm building right now
Simple IoT Project
In progressA small IoT experiment connecting a microcontroller to a web dashboard — live sensor readings and a basic remote control panel, sent over MQTT.
Have something like this in mind? I'm open to building it.
