Development

Python development

Python backends, data pipelines and AI services in FastAPI and Django that hold up under real traffic.

In short

We build Python backends with FastAPI and Django: APIs that wrap LLMs and agents, document and OCR pipelines, scraping and ETL jobs, and real services made from your data team's notebooks. A new service is typically designed in a week and live with monitoring and alerts by week seven.

Python for the parts where AI and data live.

Python is where AI and data engineering happen, so it's at the core of most of our AI work. We build FastAPI services that wrap models and agents, Django applications for data-heavy products, and pipelines that clean, enrich and move data where it needs to be.

We write modern, typed Python with Pydantic validation, async where it helps, tests and containerised deployments, so your AI backend is as dependable as the rest of your stack.

Typical projects include LLM and agent backends, document processing and OCR pipelines, scraping and enrichment, analytics APIs and integrations with ML models your data team already built.

Is this for you?

You'll get the most out of this if

  • You need a backend for an AI agent or LLM feature
  • Your data team built models in notebooks that now need to become real services
  • You process documents, PDFs or images at volume
  • You need reliable scraping, enrichment or ETL jobs
  • You want a Django admin-backed internal tool quickly

    Build

    Services and pipelines with tests, shipped to staging continuously.

  3. Week 7

    Go live

    Deployment, monitoring, alerting and load testing.

Why a small studio

The person who scopes your project is the one who builds it, and the one who picks up when it breaks at 2am.

The founder is on your project
Hussain leads every build himself. You won't brief an account manager who briefs a developer who briefs someone else.
Three people, the output of ten
We build with Claude, Codex and our own agent tooling every day. A small senior team now covers what used to need a department.
We stay after launch
Evals before every release, a log of each AI decision, cost limits and someone on call. Month six matters more to us than demo day.
Your repo, your cloud
The code sits in your GitHub and runs in your AWS, GCP or Azure account from the first commit, on tools your next hire already knows.

FAQ

Questions people ask

FastAPI or Django?

FastAPI for APIs and AI services, where speed and async matter. Django when you need an admin panel, ORM-heavy features and a full web app quickly.

Can you productionise our data scientists' notebooks?

Yes. We turn notebook code into tested, versioned services and pipelines, keeping your data team's logic intact.

Do you use Python for machine learning beyond LLMs?

Yes, for classification, recommendation and computer vision tasks with scikit-learn, PyTorch and hosted models, though we'll always check whether an LLM or a simpler rule does the job first.
