Cases
What we have delivered, in the words you would use for it.
Every case here is work the company delivered itself, said in the words a customer would use rather than the words an engineer would. Each one links to the full record behind it — the situation, the task, what was actually done and what came of it — because a claim you cannot check is only a claim.
Every case here was delivered by Engineer ApS itself. The wider record goes back to 2003 and includes work delivered by our founder inside client teams before the company existed — we say which is which rather than blurring it.
A tenth of the cloud bill, and nothing lost
Work carried out: 2025
Rethought the whole infrastructure and moved it off AWS, cutting the running costs to a tenth with no drop in what the team got done.
A mapping product, carried end to end
Work carried out: 2025
Infrastructure, data processing and the map application itself, built and kept running for two years.
Three locks on the door, none of them locked
Work carried out: 2026
Audited the server's intrusion defences and found all three had never worked: one watched the wrong door, one was overruled by a broader rule, and one could not run at all.
Backups that have actually been restored
Work carried out: 2026
Set up encrypted off-site backups that test themselves every month, so the day you need them is never the day you find out whether they work.
A whole company on one small server
Work carried out: 2026
Ran the code hosting, seven websites, the privacy network and the backups for an entire company on a single 512 MB machine, by treating memory as the binding design constraint.
Servers you can rebuild from scratch
Work carried out: 2026
Wrote the whole server setup down as code, so a machine can be rebuilt exactly as it stands today and every change is reviewed before it reaches the live system.
An app that ate 41 MB a second, stopped
Work carried out: 2026
Traced an application filling the machine's memory until it froze, and fixed the cause: 111 GB of waste on a 36 GB laptop, brought down to nothing.
A safety net that no longer costs half an hour
Work carried out: 2026
Cut the automated checks guarding every release from 27 minutes to 10, by running them in the right order and several at a time.
Know the licence of everything you ship
Work carried out: 2026
Put a licence check on 644 third-party components that runs on every build, and proved it fires by breaking it on purpose.
Your code on your own hardware
Work carried out: 2026
Set up private code hosting on the company's own server, reachable only through one controlled entry point, with no public web panel to attack.
