Backend Engineering

The part nobody sees, and the part that decides whether your product survives a busy Monday.

What this includes

  • API design and development
  • Database architecture and query optimization
  • Background jobs, queues and scheduled work
  • Authentication, roles and audit trails

When the backend is wrong, everything downstream looks broken

Slow checkout. Reports that time out. Two staff editing the same record and one of them losing their work. These read like frontend bugs to your customers, but they live in the data layer.

What we fix

  • Queries that scan whole tables because nobody added the index
  • Endpoints doing five things when they should do one
  • Missing transactions, so a half-finished order stays half-finished forever
  • No visibility — you find out something broke when a customer tells you

We measure before and after

Every optimization engagement starts with numbers: current response times, slowest queries, error rates. You get the same numbers again at the end. If they did not move, we did not do our job.

See what that looked like on a live ticketing platform in the ticketing system case study.

Questions we get asked

Can you work on a codebase we did not build with you?

Yes, and it is most of what we do. We start with a read-only audit: what the system does, where the risk sits, what one change would help most. You decide whether to continue after seeing that.

Do we have to rewrite everything?

Almost never, and we will argue against it. Rewrites take longer than anyone estimates and stop your business from shipping meanwhile. We look for the smallest change that removes the pain first.
