Python Development Services for UK SaaS, Proptech, and Data Teams
Python development services build and maintain the server-side of your product in Python: Django and FastAPI backends, REST and async APIs, data pipelines, and the engineering behind AI features. MicroPyramid has 12+ years of Python delivery and builds these for UK startups, SMBs, and enterprises.
Why UK Teams Choose Our Python Team
Three reasons UK founders and product teams pick MicroPyramid over a local agency or a generic offshore shop
Privacy-Aware Delivery, UK Data Residency
Data models, third-party integrations, and storage choices are made with personal data in mind from the first sprint. AWS eu-west-2 (London) is available for UK data residency.
GBP Billing via Stripe or GoCardless
Invoices in GBP, collected via Stripe or GoCardless Direct Debit. No currency conversion headaches, no wire-transfer friction. Billing that fits how UK businesses actually operate.
Direct Ownership, Not a Ticket Mill
Experienced Python engineers directly own every engagement. You will not be passed to a delivery layer of junior developers. The engineer who scopes your backend in discovery is the one who builds it.
Python Development Services for UK Teams
Six services spanning the Python backend lifecycle, from UK-focused MVPs and APIs to data engineering and AI-ready features
Python Backend Development
Production Python backends built on Django and FastAPI for UK SaaS and proptech products. We own the business logic, data models, and service architecture that the rest of your product depends on.
- Django and Django REST Framework
- FastAPI for high-throughput services
- Clean, testable service architecture
API Design & Integration
REST and async APIs that other systems can rely on, built for the integrations UK products actually need: payment providers such as Stripe, CRMs, accounting platforms, and partner data feeds.
- REST and async API design
- Third-party and payment API integrations
- Versioned, documented endpoints
Data Engineering & Analytics
Turn raw data into reporting, dashboards, and decision support using the Python data stack. Pipelines and models hosted on AWS eu-west-2 (London) when UK data residency matters.
- ETL and data pipelines
- NumPy, pandas, and SciPy workflows
- Reporting and analytics services
Process Automation
Automate the repetitive, error-prone work draining your team (document processing, scheduled jobs, scraping, and back-office workflows) with Celery-backed Python automation.
- Celery and async task queues
- Scheduled jobs and workflow automation
- Scraping and document processing
Python Modernisation & Rescue
Improve a Python or Django product already serving paying UK customers: audits, architecture cleanup, performance fixes, and security hardening without destabilising what works.
- Codebase audits and refactoring
- Performance and query optimisation
- Security and dependency hardening
AI-Ready Python Features
Python is the natural home for AI in your product. We build the retrieval, embedding, and orchestration layers that turn LLMs into useful features: search, copilots, and automation.
- Retrieval-backed features (RAG)
- LLM orchestration and pipelines
- Semantic search and copilots
Django or FastAPI? How to Choose
The two frameworks solve different problems, and many UK products use both. Here is the honest version, so you pick the right tool rather than the trendy one. We help you make the call in discovery, before any build commitment.
Choose Django when…
- You want a full-featured web app with admin, auth, and ORM out of the box
- You are building a SaaS, portal, marketplace, or content-driven product
- You value batteries-included security defaults for careful personal-data handling
- Team velocity and convention-over-configuration matter more than raw async throughput
Choose FastAPI when…
- You need a high-performance, type-safe API or microservice
- You are serving AI/LLM features, RAG endpoints, or heavy async I/O
- OpenAPI-first contracts and Pydantic validation are priorities
- You want a lightweight service rather than a full web framework

Best Fit For
- UK proptech or SaaS teams running Python and Django in production
- startups, SMBs, and enterprises that need backend, APIs, and data delivery owned end-to-end
- MVPs and feature sprints where privacy-aware architecture matters from day one
- Python or Django products that need engineering judgement on performance, security, and scale
Not the Right Fit When
- pure frontend or marketing-site work with no backend complexity behind it
- engagements looking only for staff augmentation without delivery ownership
- languages outside the Python ecosystem where we add no real advantage
- teams adding AI as a slogan rather than a concrete Python-backed feature

How to Get Started as a UK Team
We recommend starting with a Python Discovery Sprint: clarify the backend and delivery plan before committing to a full build. All engagements billed in GBP.
Python Discovery Sprint
Recommended start
Clarify the backend, APIs, data model, and delivery plan before committing to a full build. Billed in GBP, delivered with daily async updates.
- Backend problem clarification
- API and data architecture
- Delivery roadmap
- Stack and hosting decisions
MVP Sprint
Ship a focused first Python version with Django or FastAPI foundations that are genuinely ready to iterate on, not a prototype you will throw away.
- Launchable backend slice
- Django or FastAPI foundations
- Clear deliverables and timeline
Backend Delivery Sprint
Implement one meaningful Python improvement end-to-end (a new API, a data pipeline, or a performance fix).
- One meaningful backend improvement
- End-to-end implementation
- Retainer or time-and-material

Straight answers to what UK founders and CTOs ask us before starting a Python project.
What do Python development services include?
Python development services cover building and maintaining the server-side of your product in Python: typically Django or FastAPI backends, REST and async APIs, data pipelines and automation, and the retrieval and orchestration layers behind AI features. At MicroPyramid we own the business logic, data models, and service architecture your UK product depends on, from a first MVP through to scaling an existing backend.
Is Python a good choice for a regulated UK product?
Yes. Python, especially Django, ships with mature authentication, ORM-level protections, and secure defaults that make it straightforward to build careful data handling, audit trails, and access controls. For regulated and data-sensitive products we map personal data flows from day one, and deploy to AWS eu-west-2 (London) so your data and backups stay in the UK.
Where will my Python application and data be hosted?
We deploy to AWS eu-west-2 (London) by default for UK clients, so your data, backups, and processing stay within the UK, which keeps data residency questions from customers simple to answer. If you already have cloud infrastructure, we are equally comfortable working within your existing AWS, Azure, or GCP account.
What drives the cost of a Python project?
The main drivers are scope and feature count, the complexity of your data model, the number of third-party and payment integrations, and any compliance or security requirements. We do not quote blind or run an open-ended hourly meter. After a short discovery sprint we give you a fixed estimate, billed in GBP via Stripe or GoCardless, so you know the scope and price before any build sprint starts.
How long does it take to build a Python application?
It depends on scope: the number of features and integrations, the data model, and whether we start from scratch or from existing code. The discovery sprint gives you a timeline and fixed estimate before any build starts, and we then work in weekly sprints with a demo each sprint.
Can you take over or rescue an existing Python or Django codebase?
Yes. We audit the codebase, dependencies, and security, fix performance bottlenecks and slow queries, upgrade out-of-date Django and Python versions, and modernise the architecture incrementally, without a risky full rewrite. Inherited, undocumented codebases from a departed agency or contractor are squarely in scope; for deeper version work see our UK Django modernization service.
Can you build AI features into a Python backend?
Yes. Python is the default language for AI, and we build LLM features, RAG pipelines, semantic search, and AI agents directly into your Django or FastAPI backend, adding AI chat, search, and automation inside your product rather than bolting on a separate system.
Who actually writes the code?
You work directly with the Python engineers building your backend, not account managers or a rotating bench of junior developers.
Who owns the code and IP?
You do, fully, from day one. We sign NDAs and IP-assignment before work begins, and you keep complete ownership of the source code, IP, and infrastructure throughout and after the engagement.
