Backend
Backend and API development
We build the APIs, integrations, data pipelines and automation behind apps and websites, designed to be reliable, observable and inexpensive to run.
Most of what makes a product work happens out of sight: the API behind the app, the jobs that process data overnight, the integrations with payment providers and third-party services.
We build backends in TypeScript and Python, choose managed and serverless infrastructure where it keeps costs and maintenance down, and add monitoring from day one so problems are visible before users notice.
What we build
APIs
Typed, documented APIs for apps and partners, with authentication, rate limits and versioning.
Integrations
Payments, email, maps, analytics and third-party APIs, connected reliably with retries and clear error handling.
Data pipelines
Jobs that collect, process and store data, from image processing to blockchain event indexing.
Automation
Scheduled tasks, bots and keepers that act on time, with alerts when they can't.
Serverless and edge
Cloudflare Workers and managed services that scale without servers to look after.
Monitoring
Logs, metrics and alerts, so you know when something is wrong and why.
How a project runs
- 01
Discover
We learn about your users and goals, agree the scope of version one and quote a fixed price.
- 02
Design
Prototypes and technical designs before production code, so changes stay cheap.
- 03
Build
Short iterations with weekly progress and tests written alongside the code.
- 04
Ship
Launch, monitoring and App Store or deployment work, then improvements based on real use.
What makes a backend reliable
Idempotency and retries
Operations that are safe to repeat, so a network blip never charges a customer twice.
Security
Authentication, least-privilege access and secrets kept out of code.
Observability
Structured logs and metrics that explain what happened, not just that something failed.
Running costs
Infrastructure sized to your traffic, without paying for idle servers.
Questions
Can you build the backend for our app?
Yes: the API, database, accounts and integrations your iOS or web app needs.
Do you work with existing systems?
Yes. We often integrate with or gradually replace existing services rather than starting from scratch.
Which cloud providers do you use?
We often use Cloudflare and managed databases, and work with AWS or Google Cloud where a project already lives there.
Do you provide ongoing support?
Yes, through a monthly arrangement covering monitoring, fixes and improvements.
