Services
Python & FastAPI
backend development.
We design and build the APIs, business logic and data models behind your product, or extend the backend you already have. Python is our main language, with FastAPI and Django doing most of the work.
What we do
- New APIs and services
- REST APIs in FastAPI or Django, designed around your domain, with validation, authentication and documentation your frontend and partners can rely on.
- Data models and business logic
- SQLAlchemy and PostgreSQL models that reflect how your business works, with migrations that are safe to run in production.
- Extending an existing codebase
- We read the code you have, understand its constraints and add what you need without a rewrite nobody asked for.
- Tests and handover
- Automated tests, useful documentation and release notes, so your team can run and extend what we build.
Experience behind it
Our backend work has covered quotes, payments and claims for a digital insurer, evidence analysis for a digital forensics platform, and integrations for travel and fitness businesses.
Common questions
Should we use FastAPI or Django?
It depends on the product. FastAPI suits API-first services where typed request handling and performance matter. Django suits products that benefit from its admin, ORM and conventions. We work with both and recommend one based on your team and constraints.
Can you take over an existing Python codebase?
Yes. We start by reviewing the code, the deployment and the known problems, then agree a focused first piece of work.
Do you only work on the backend?
Backend is our focus. We also build with TypeScript, React and Next.js when a project needs an interface around the backend.
