Python backend development for products that have to integrate.
APIs, background processing, and data models in Django and FastAPI on Postgres. The same backend our integrations run on, for your product, from a first version to running it in production.
What we build
APIs and services
REST APIs in FastAPI or Django, with clear contracts for your frontend, mobile app, or partners.
Background processing
RabbitMQ and Celery for work that should not block a request: webhooks, imports, emails, and AI calls.
Data modelling on Postgres
Schemas, migrations, and queries designed around how the product is used, with Redis for caching and short-lived state.
Turnkey products
When there is nothing to integrate into yet, we build the product: backend, React frontend, payments, and deployment.
Stack, and why
Python
One language for web, data, and AI work, with mature libraries for all three.
Django
Admin, auth, and ORM out of the box. The fast route for products with a lot of business logic.
FastAPI
Lightweight async services where latency matters, such as AI and integration endpoints.
Postgres
One reliable database for relational data, JSON, and vectors through pgvector.
Redis
Caching, rate limits, and short-lived state.
RabbitMQ and Celery
Background jobs with retries and scheduling.
React
Frontends and admin dashboards when the product needs a UI.

How a project runs
- 1CallA short call about what needs to be built or connected, and why it matters to your product.
- 2Discovery sprintWe map your systems, the external APIs, and the risks, then give you a range of hours.
- 3Build in short iterationsWorking pieces in your environment as we go, not a big reveal at the end.
- 4Launch and afterRelease with monitoring, then a handover to your team or ongoing support on the Scale tier.
How we bill
Hourly or monthly. Never a fixed price per project.
Hourly or a monthly block
You pay for the hours we work, or a fixed monthly amount for a reserved block of hours. Either way, you can scale up or down between months.
Why no fixed project price
Integrations always hide surprises: an undocumented rate limit, a webhook that fires twice, data that does not match between systems. A fixed price means either padding it for every risk or cutting corners when one shows up. We estimate a range of hours instead and revise it as we learn.
Starting small
A short call, then a discovery sprint to map your systems, the third-party services, and the risks before anyone commits to an estimate.

FAQ
Django or FastAPI?
Django when the product has a lot of business logic and needs an admin and auth from day one. FastAPI for lean, latency-sensitive services. Many products use both: Django for the core, FastAPI for AI or integration endpoints.
Do you also build the frontend?
Yes, in React, when the product needs one. For integration work we usually plug into the frontend you already have.
Who runs it after launch?
Either your team, after a handover with documentation, or us on the Scale tier with production on-call.
How do you price it?
Hourly or as a monthly block of hours. We do not quote a fixed price per project.
