Services
What we take on
Each one states what you get and how long it takes.
Product design
We turn a pile of unresolved ideas into something you can ship, measure and keep growing. The problem gets stated plainly before a single screen is drawn.
Web and frontend engineering
Sites that search engines can read, that open on a slow connection, and that are still editable in three years. Performance and accessibility are acceptance criteria, not bonus points.
Platform and backend engineering
Backends split into a few services with honest boundaries, running at the edge. Cold starts, connection limits and cross-region latency get solved in the architecture, not in production.
Work
Things we have built
The numbers are the clients’ own measurements, not our estimates.
Kaiho Freight
2025
Thirty years of paper moved online without a single day of downtime
Customs, capacity and reconciliation lived across four systems and a great deal of Excel. We replaced all of it in nine months while shipments kept moving.

Lumen Clinics
2024
Booking that works the first time, including for older patients
Three in ten online bookings were abandoned midway. We rebuilt the flow and reset type scale, contrast and touch targets against real accessibility criteria.

TSUKI
2025
Three markets, one commerce backend
Tax, payment and fulfilment rules for Taipei, Tokyo and Singapore collapsed into a single configurable rules engine.
3markets, one system
In the first meeting they told us the feature we came in asking for was the wrong thing to build. That sentence saved us more than the project cost.
Insights
How we think about this work
Every piece comes out of a project we actually ran, including the decisions we nearly got wrong.
Do not migrate in one go
Nine months to replace four systems, without stopping shipping for a single day. What made that possible was not careful planning — it was giving up on the idea of a cutover.
Put the performance budget before the merge
A monitoring dashboard after release looks impressive and prevents nothing. The number has to appear while someone is still willing to fix it.
Do not interpolate: draw the holes in your data
An interpolated line looks perfectly healthy, and that is exactly the problem. We made the dashboard uglier, and it caught a six-hour outage.
