Cases

A selection of the work: what the client needed, what was built, and what it changed. Each case links through to the full write-up.

The POS sale screen, recreated with sample products: a grid of Thai market goods with per-seller badges, a basket split across three sellers, and a Charge ฿290 button offering cash or PromptPay QR.

One till, many sellers: a market POS that splits every sale by stall

A community market in Thailand (client kept anonymous)
Retail — point of sale

A point-of-sale system for a physical market where dozens of independent sellers share the same tills. A cashier rings up one basket; the system knows which stall every item belongs to, splits the sale per seller at the moment it happens, and keeps the books each stall settles against. Thai-first interface with a synchronized English translation set, built on Laravel 12 with a Filament v4 admin panel and PostgreSQL underneath.

The rebuilt Ideahunters front page on Drupal 11: the tagline 'Great ideas, sourced from the crowd' over a blue-green hero card, with an archived brand challenge below.

Fifteen years of community ideas, carried from Drupal 7 to Drupal 11

Ideahunters — crowdsourced-challenge platform
Community platforms / legacy migration

Ideahunters is a crowdsourcing platform where brands post a challenge and a community submits ideas against a deadline. The original site ran on Drupal 7 — end-of-life, unsupported, and increasingly a liability — with over a decade of challenges, discussions and member accounts in it. The platform was rebuilt on Drupal 11 and the legacy content migrated across: 426 pieces of content and 921 user accounts, anonymized on the way in.

The TableFlow booking page: the hour grid for Bord 4 on 19 August 2026, with three hours struck through as taken, 10:00-12:00 selected in green, and the price updated live to 40 kr.

Danish coworking space — client brief, built as a working demo
Coworking and shared offices

A Danish coworking space wanted members to book a table by the hour and pay for it — because at 20 kr. per hour per table, a booking that has not been paid for is not a booking. tableflow.grn.dk is that system, built from the client's brief and running live: an hour grid that shows what is actually free, a fifteen-minute payment hold that releases itself, and an admin screen for the people who run the place. Plain PHP and MariaDB — no framework, no dependencies, 853 lines in seven files.

Most of these started as a one-line idea on a kanban card. Tell me yours and I will tell you what it would take.
