Python Development Agency · Django, FastAPI, Async Python in Production

Python for backend services where the data, the AI integrations, or the regulatory shape of the workload favours Python's ecosystem. Django for batteries-included applications. FastAPI for modern async APIs. Both with the production hardening Python earned a reputation for skipping.

Why HXRL

Our point of view

Python is back in the conversation because of AI — and because FastAPI made async Python actually pleasant. We pick Python when the integrations (ML, data, scientific libs) tip the decision, and we ship it with the same observability and CI rigour we'd apply to any Node service.

Outcome

Python services that hold up in production — typed, observable, and deployable like any other backend stack.

What we ship

Python Development

Concrete deliverables — not adjectives. Each engagement scopes which of these are in play and what success looks like for them.

FAQ

Questions clients actually ask

Drawn from sales calls, not SEO filler. Want a question added? Drop it in the form on this page — we update from real enquiries.

Django or FastAPI?+

Django when you want admin, ORM, auth, and migrations bundled. FastAPI when you want a modern async API surface and you're comfortable assembling the rest. We use both.

Is Python fast enough for production APIs?+

FastAPI on async Python with Uvicorn workers is genuinely fast — comparable to Node for most workloads. The historic Python latency story doesn't apply to async stacks.

Do you use Python for AI features?+

Yes — LangChain, LlamaIndex, and direct SDK integrations (OpenAI, Anthropic). See our AI & Data Engineering capability for the full story.

Type hints and mypy — do you bother?+

Always. We run mypy or pyright in CI. Untyped Python in 2026 is a future-pain choice we won't make.
