Work that
shipped and stayed up.

A selection of what we have built and secured. Client names are only published with permission — where we cannot name a client, we describe the environment and the result instead.

Gadget Exchange

An online store for consumer electronics — catalogue, accounts, orders and checkout — built from the ground up instead of assembled out of plugins, so every part of it can be changed when the business needs it changed.

Payments run through a crypto wallet we wrote ourselves. It receives what customers pay and sends payouts back out on-chain, with no payment processor in between and nobody taking a cut of a transaction. The shop, the wallet and the infrastructure belong to the business that runs them.

Bookkeeping ERP · DACH region

A double-entry bookkeeping system built for how accounting is actually done in Germany, Austria and Switzerland — chart of accounts, VAT handling, postings and reporting, written from scratch rather than bent out of an off-the-shelf product. Currently under development.

Bookkeeping ERP · United States

The same engine, built for US small businesses: double-entry bookkeeping, US accounting rules and the reports a small company and its accountant actually need, without the per-seat pricing of the big suites. Currently under development.

How we write these up

Four things, every time.

No vague claims. If a number is in here, we can show where it came from.

01

The situation

The environment as we found it, including what was already working.

02

The scope

What was agreed in writing, and what was deliberately left out.

03

The work

What we implemented, in what order, and who did it.

04

The result

What measurably changed, and what the client runs today.

Between the case studies

Not every engagement becomes a story.

A lot of our work is quiet: a tenant hardened over a weekend, a backup that finally restores, an SSP that turns a stalled contract into a signed one. Ask us about your situation and we will tell you whether we have solved it before.
