Python development
Python is the fastest path from idea to working software, and the default language of modern data and AI. We build clean, typed Python services and the pipelines and models that sit behind them.
In short
Python, at a glance
- Clean syntax means faster onboarding, fewer bugs and code that survives team changes.
- The default language for data science, ML and LLMs. The whole toolchain lives here.
- A vast standard library plus PyPI cover almost any problem you'll meet.
- Go from idea to working prototype in days, then harden it for production.
Why Python
Python in production.
Python's readability means teams move fast without leaving an unmaintainable mess behind. Its standard library and package ecosystem cover everything from web APIs to scientific computing.
We write modern, type-annotated Python (FastAPI for services, Pandas and Polars for data, PyTorch and scikit-learn for models) with the testing and observability that turn a prototype into production software.
Readable & expressive
Clean syntax means faster onboarding, fewer bugs and code that survives team changes.
Data & AI native
The default language for data science, ML and LLMs. The whole toolchain lives here.
Batteries included
A vast standard library plus PyPI cover almost any problem you'll meet.
Fast to build
Go from idea to working prototype in days, then harden it for production.
Runs everywhere
The universal glue language: servers, notebooks, edge devices and pipelines.
Huge talent pool
One of the world's most-used languages means easy hiring and deep community support.
From prototype to production
The same language carries a model from a notebook through a tested pipeline to a monitored service in production.
How we engineer
with Python.
How we work
Senior engineers, accountable to outcomes. Every change typed, reviewed and tested.
01API & backend development
Async, typed services built with FastAPI or Django: fast, documented and production-ready.
- FastAPI / Django REST
- Async I/O & background jobs
- Auto-generated OpenAPI docs
02Data engineering & pipelines
ETL/ELT pipelines that move and transform data reliably into a warehouse your team can trust.
- Airflow / Dagster orchestration
- dbt transformations
- Data quality & lineage
03AI / ML & LLM features
Applied AI wired into real product workflows, from classical models to RAG and agents.
- RAG & vector search
- LLM orchestration
- Model serving & evals
04Automation & scripting
Replace manual, error-prone work with reliable automation and internal tooling.
- Back-office automation
- Web scraping & integrations
- Scheduled jobs
05Scientific & analytics tooling
Numerical and analytical software built on Pandas, Polars and NumPy.
- Pandas / Polars / NumPy
- Reproducible notebooks
- Interactive dashboards
06Maintenance & modernisation
Bring legacy Python 2/early-3 code up to a modern, typed, tested baseline.
- Type-hint adoption
- Test coverage
- Dependency & runtime upgrades

Tooling
A look at what we've shipped.
A real-time wealth platform built for scale
Re-architecting a legacy investment portal into a modular, real-time platform that holds up under heavy concurrent load.
View case studyA six-step cycle, repeated until it's right.
Transparent, predictable and collaborative. You always know what's shipping next and why.
Discovery
We map the business, users and constraints, then pressure-test the problem before a line of code.
Planning
Architecture, scope, and a sprint roadmap with clear milestones, budgets and success metrics.
Design
Research-led UX and high-fidelity interfaces, validated with prototypes before build.
Development
Senior-led engineering in two-week sprints with demoable increments and continuous review.
Testing & QA
Automated and manual testing, security review and performance hardening before release.
Launch & Care
Confident deployment, monitoring and SLA-backed support that keeps things humming.
Python questions, answered.
Still unsure if Python is right for your project? A senior engineer will tell you straight on a free call.
Backend APIs, data engineering, analytics, automation and anything AI/ML. It's the default language for data science and LLM work, and a productive choice for web services with FastAPI or Django.
For the I/O-bound work most web services do, yes, especially with async FastAPI. For CPU-heavy hot paths we lean on optimised libraries (NumPy, Polars) or drop into compiled extensions where it matters.
Yes. We build RAG systems, LLM-powered features, recommendation and classification models, and the evaluation harnesses that keep them honest, then ship them as real, monitored services.
FastAPI for lean, async, API-first services; Django when you want a batteries-included framework with an admin, ORM and auth out of the box. We'll recommend based on your team and roadmap.
Type hints checked with mypy, linting and formatting with Ruff, tests with Pytest, and dependency management with Poetry, all enforced in CI so quality doesn't drift.
