JG Core
My projects, built as an island, with railway lines between them.
Every project is a building in its own colours. The Money, Life, Care, Property, Trade, Civic and Play lines run between them, and old versions rest in the graveyard. Drag to turn the island, use two fingers to move about, and tap a building to read about it. Or press Walk and wander round it as a stickman.
Work
I design, build and run software, start to finish.
Everything here I planned and built, and I run it through my company, JG Core Ltd. If you have something that needs building, I would like to hear about it.

CoreFi is the flagship.

Commercial lease reviews by independent solicitors
Instrukt introduces businesses that need a commercial lease reviewed to an independent, SRA-regulated property solicitor, who reviews it and explains it in plain English.

Mobile quoting app for a blinds and awnings manufacturer

On hold

Landed cost, stock and cash for Amazon sellers who import
Works out what a unit of imported stock actually costs (freight, duty and trade remedies included) and reconciles it against what customs charged, then plans from that number: when each listing must be reordered, what running out would cost, what the order plan does to the bank balance, and what Amazon owes back in refunds and lost stock. For sellers who are the importer of record. The site is live; the product itself is in build.

Workshop
Where the stickmen are drawn.
The stickman lab: where the people on this island learnt to walk, with straight limbs, planted feet and no faces. Small experiments start here before they get a building of their own.
Workshop
Which notes ring out, for any chord in any tuning.
An idea for guitarists: pick a chord and a tuning, standard or something stranger, and see the actual note on every string, with the root, third, fifth and seventh each marked in their own colour. Planned, not built yet.
Just an idea so far.
Workshop

Where old versions go.
