Systems that are still
shipping in year five.
Service and API architecture, domain modelling and custom middleware — for systems we build, and for systems we inherit.
What Attri’s application engineering practice covers
Attri designs the service boundaries and the domain model, build the APIs and middleware the business logic needs, and integrate what the company already runs. Then we stay for the part most engagements skip.
New builds
Greenfield systems taken to production, with the performance and reliability work that starts after launch rather than ending at it.
Inherited codebases
A platform with years of history and no original authors. We get it releasable first, then start shipping into it.
Long-run ownership
Profiling, query tuning, retry semantics and the failure modes that only appear under real traffic.
What we build with
We build in the estate you already run, including the parts you inherited, rather than moving you onto what we would have picked.
- ASP.NET Core 6/8/10
- Spring Boot
- Node.js
- Python
- TypeScript
- React / Next.js
- REST / OpenAPI
- Microservices
- SQL Server / PostgreSQL
- Kubernetes
Where we put agents in application delivery
Agents take on the work that scales with volume rather than judgement. What they produce goes to the engineer who owns that area before any of it ships.
Reading the codebase
Agents map call graphs and surface dead paths, so an engineer opens their first pull request against a system they understand rather than one they are guessing at.
Writing the tests
Characterisation tests generated against existing behaviour, reviewed by the engineer who will own them.
The repetitive middle
Controllers, DTOs and migrations generated from the API contract, so judgement goes into the domain model.
Put agents on your estate.
See how we scope, govern and deploy them — with the guardrails regulated teams need.
Tell us what you are running.
A system to build, or one you have inherited. Either way the first conversation is the same: what exists, what is breaking, and what has to stay live while it changes.
