I founded Engineer ApS in Copenhagen after two decades of building and running the systems companies depend on — platforms, data pipelines, databases, and the teams around them. Most of the portfolio on this site is work I delivered inside client teams before the company existed: every entry is something delivered, with the situation it started from and the result it reached.
Engineer ApS was registered in 2025. The engineering behind it started a good deal earlier.
This page also answers to its own two addresses, if either is easier to remember or to pass on: ditte.engineer.company and daryna.engineer.company. Both open on this introduction and the recommendations that go with it, without the rest of the company in the way — and both name this page as the original, so there is one of me on the internet rather than three.
- Cut infrastructure costs 10 times with zero loss in productivity by redesigning the infrastructure and moving it off AWS.
- Made a geographical data pipeline 50x faster through better SQL and data modeling, and PostgreSQL 10x faster through indexing, partitioning and query tuning.
- Led the software development of a GIS map application to 10x revenue growth.
- Grew a team from 2 to 18 members and saved 4,000 hours through mentoring and better workflows.
- Kept infrastructure reproducible: Azure as code in Bicep, Ansible playbooks, own monitoring and backups with a monthly restore drill.
- Domain knowledge in GIS systems, electricity networks and maritime platforms.
