Back-end technology

Python Development Services

Python is our default for data-heavy backends, APIs and automation. We build with FastAPI or Django, type-annotated and tested, and we know how to take Python services to production and keep them there.

  • Async where it helps

Why Python

Why teams choose Python

Fast to build, clear to read

Python's readability keeps delivery quick and onboarding painless.

The language of data and AI

The same stack that serves your API also runs your models, pipelines and analytics.

Mature web frameworks

Django for batteries-included products, FastAPI for high-throughput typed APIs.

A huge standard library and ecosystem

Whatever the integration, there is a well-maintained package for it.

Use cases

What we build with Python

REST and GraphQL APIs

Typed, documented services that other teams and mobile apps consume.

Data pipelines and ETL

Scheduled and streaming jobs that move and reshape data reliably.

AI and ML features

Retrieval systems, model serving and evaluation next to the product code.

Internal platforms and admin

Django admin and custom tooling that ops teams actually like.

How we work

How we build Python products

The same delivery discipline on every engagement, whatever the stack.

Discovery before code

A short kickoff to agree scope, architecture and the riskiest assumptions, so the first sprint moves in the right direction.

Trunk-based delivery

Small pull requests reviewed within hours, merged behind feature flags, and deployed continuously.

Tests that pay for themselves

Unit tests for logic, integration tests for the seams, and a thin layer of end-to-end tests on the paths that matter.

Observability from day one

Structured logs, traces and dashboards in place before launch, not after the first incident.

Documented and handed over

Architecture decision records, a running runbook, and a codebase your own team can own the day we leave.

Stack

The Python stack we reach for

Sensible defaults, not a fixed menu. We adapt to what your team already runs.

FAQ

Python FAQ

Django or FastAPI?

Django when you want an admin, ORM, auth and templating out of the box. FastAPI when the service is API-only and throughput or typing is the priority. They also coexist well.

Is Python fast enough for production?

For the vast majority of web workloads, yes, especially with async frameworks and proper caching. Where a hot path needs more, we profile and optimize, or move that piece to a faster runtime.

Do you type-annotate Python?

Yes. We use type hints everywhere, check them with mypy in CI, and validate data at the edges with Pydantic.

Can Python serve our AI models?

That is one of its strengths. We serve models behind FastAPI, add evaluation and guardrails, and keep inference observable.
