Capabilities

The toolkit, and how deep it goes

These are the tools behind 8 self-published CodeCanyon products, 2 Shopify App Store apps, and a further catalogue built for employers — not a list of things I have read about. Grouped by where each sits in a system, with no self-scored percentages, because shipped work is the only useful measure.

  • CodeCanyon author

    Envato marketplace

    A further catalogue was built under the Inilabs author account during that role, including Inilabs School Express at 2,373 sales.
