Backends and APIs
The APIs, data models and integrations underneath your product: tested on every change, observable in production, and documented for the next engineer.
- Built withNode.js or Python, Postgres
- Every changeTested before it merges
- In productionLogs, metrics and alerts
What a backend looks like
One API for every app, with slow work moved out of the way of your users.
One API
The contract written first, so web, mobile and partners build against the same thing.
Data
Postgres, with a clear model and migrations reviewed before they reach production.
Queue and jobs
Slow work like exports, emails and AI calls runs in the background and retries on failure.
Integrations
Payments, CRM and email providers called safely, so a retry never charges twice.
Built to stay up
The habits that keep a backend boring in production.
- Load tested
The busy paths tested at more than your expected traffic before launch.
- Backups proven
Backups restored on purpose, so we know they work before you need them.
- Observable
Logs, metrics and alerts that point to the cause, not just the symptom.
- Documented
An API reference and a runbook, so on-call does not depend on one person.
Questions about backends
What usually comes up on the consult.
Monolith or microservices?
Usually one well-structured service first. It is faster to build and change; we split parts out only when there is a measured reason.
Which database?
Postgres for most products, including vector search for AI features. We work with what you run when there is a reason to keep it.
Our backend is slow. Can you fix it?
Yes. We measure first, fix the slowest paths, and show the before and after numbers.
Where does it run?
In your own cloud account, AWS, Google Cloud or Azure, so you own it and pay the provider directly.
