Clients

Seven companies, two sizes, three sectors.

Here is what we did for them. Where we can say the number, it is there. Where we cannot, there is one honest line.

Three stories with numbers

Critical infrastructure · NIS2

Sinal / Norlys

Energy and fibre · 2025–2026

A complex estate of order and provisioning systems with no joint overview: when a fibre order stalled, nobody knew where.

A modern, open-source observability platform that can trace an order across the systems, designed and put into production in an OT environment under NIS2 requirements. Alongside it, architecture for Seamless Customer Journey and the optimisation of points of interconnect.

In production in six months.

Where the habits come from

Danske Bank

Finance · 2014–2016

MobilePay stood on a mainframe platform that could not keep up with growth, and the business customers’ online bank had to be built anew.

The target architecture for MobilePay’s new platform: .NET, event-driven SOA, Cassandra as the data store. Then the financial dashboard platform which, through workshops with over 100 stakeholders and event storming, became District, the bank’s online bank for business customers.

District took over the whole business online bank. The work is ten years old, and it is where the architecture habits on this site come from.

Founded by Martin

AeroGuest

Hospitality · startup · 2016–2022

The hotel industry lacked what airlines had had for years: mobile check-in and guest identity on the phone.

The whole backend platform in .NET on Azure, event-driven with RabbitMQ and Cassandra, and technical leadership of around 50 developers and UX people across iOS, Android and web.

Hotel customers across north-western Europe and the US, IF Design Award 2019, patent DK 180628 in 2021. Martin sits on the board today.

On confidentiality

We name only clients we have worked for, and only what is public or agreed. Figures that are not here are figures we may not mention. Named references are given on request, once the client has said yes.
