Full-stack engineer for Cologne

Common questions

6 questions that actually come up about a project in Cologne — answered the way they would be answered in conversation.

01Is there on-site work in Cologne too?

Yes. Bergisch Gladbach is half an hour from the centre of Cologne, and that is how the projects ran: on site for workshops, acceptance sessions and handovers, built remotely, with weekly demos on real code.

02What are the projects here built with?

Next.js, React and TypeScript on the front end, Node and Python on the back end, PostgreSQL with pgvector as the database, Docker and AWS in operation. The complete list is in each case study, line by line.

03Can any of the projects be seen live?

SnipeFlip runs publicly at snipeflip.com. The other three ran inside client systems — what may be shown from them is in the respective case study, together with the number the project was measured by.

04Do you work alone or with a team?

Alone, and that is the point: in all four projects interface, backend, database and cloud came from the same person, so there was no handover between trades for knowledge to fall through. On the AI profile generator, team leadership came with it — from three developers to twelve in three months.

05Where does the data sit when AI is involved?

Hosting in the EU is the default, usually AWS Frankfurt or Hetzner. Where a language model is wired in, the handover document states which model sees which data, what is logged, and what never leaves the building.

06Where do the numbers on this page come from?

Each comes out of the project it was measured in: 2,500 operations a day at SnipeFlip, three minutes per profile instead of forty-five, a team from three to twelve, zero errors after the ERP switch. How it was measured is in the case study each time.
