Proprietary AI & Internal Systems
03

OkenDesk ↗

The backend every client site runs on. One multi-tenant platform serving separate businesses: an AI concierge answering from that client's own facts, an enquiries inbox, email and SMS alerts, an admin panel, and copy the owner can edit across any number of pages. Publishing a site takes about a second, with no rebuild and no downtime.

Custom operations software that turns a single artwork into finished, publishable output. Composites it into perspective-correct room mockups, produces 300 DPI print masters, and carries the work through review to completion. Built solo, in daily use by a small team.

Authoritative Media & Comparison Platforms
07

SaaSInspector ↗

A directory of SaaS tools, arranged around comparison rather than ranking. Answering a question about two products used to mean a dozen browser tabs and two marketing pages written to avoid the comparison. Here they line up column by column, the same fields in the same order, and the difference is on one screen.

08

The Coffee Guru ↗

Independent review and comparison site for coffee equipment. Around 98 products across 11 categories, scored from the manufacturer’s own published specifications rather than a weekend with one machine, with the reasoning behind each score kept on the page. No paid placements, and the order of a list is the order the scores put things in. Currently being rebuilt; the case study shows work in progress.

Client Engineering & Scale
09

keisot ↗

Custom digital gallery built for an independent art archive. Full-bleed monochrome presentation, minimal interface chrome, and a single-template architecture where the artwork is the only variable, so the collection can grow without the layout drifting.
