Python is now the most popular programming language in the world. It holds the top position in the TIOBE Index with a 22.85% rating, surpassed JavaScript as the most used language on GitHub in 2024, and according to the Stack Overflow Developer Survey, saw the largest single-year adoption jump of any major language in 2025, up 7 percentage points. More than 1.19 million job listings on LinkedIn require Python skills, and 42% of global recruiters actively seek it. That adoption reflects what Python genuinely delivers: a language that handles web development, REST APIs, data engineering, and AI integration equally well, with frameworks that keep complex applications maintainable over time. When you hire Python developers from KiwiCommerce, you get UK-based specialists who build properly on current versions, with the right framework for the job.
Python's range of use cases means the businesses hiring our Python web developers are genuinely varied. From SaaS products and eCommerce backends to data dashboards and API layers for AI-powered applications, our Python development services cover the full span of what the language is actually used for in production.
Get In TouchDjango is used by Instagram, Pinterest, and Disqus at scale because its batteries-included architecture handles complex web applications without requiring a framework to be assembled from parts. Our dedicated Python web developers build Django applications properly: with the ORM used correctly, the admin layer configured usefully, and the application structured to remain maintainable as it grows.
FastAPI is the fastest-growing Python web framework in 2025, used by Uber, Microsoft, and Cisco for high-performance, async-native API development. It is particularly well suited to APIs that integrate with data pipelines or AI models. Our Python API developers build FastAPI and Django REST Framework APIs that are documented, validated, tested, and structured for the traffic they will actually receive.
When Shopify, Magento, or WooCommerce do not fit because of the product logic, order workflow, or integration architecture, is too specific, a Python backend built on Django or FastAPI is the right answer. Our Python development company brings both Python expertise and direct eCommerce domain knowledge, which produces better decisions about catalogue structure, payment handling, and order state management than a generic Python team.
Python is the dominant language for data science, machine learning, and AI integration. not because of marketing but because the libraries NumPy, pandas, scikit-learn, and the API layers for large language models are simply better in Python than anywhere else. Our Python developers build and connect the web application and API layers that make data and AI capabilities available to real users in production.
Python is a general-purpose, high-level programming language first released by Guido van Rossum in 1991. It has been under continuous active development since, with Python 3.13 (released October 2024) and Python 3.14 (released October 2025) as the current actively maintained versions. Python 3.9 reached end of life in October 2025 and no longer receives security patches. Python 3.10 is in security-only mode and reaches end of life in October 2026. If your application is on Python 3.9 or earlier, it is a security risk and needs upgrading.
Python's language design prioritises readability and reduced boilerplate. That clarity makes large Python codebases cheaper to maintain over time compared to more verbose languages, and it is one of the primary reasons Python is the first choice for teams building products that need to be worked on consistently by multiple developers. Python 3.13 introduced significant performance improvements, including an experimental no-GIL (free-threaded) mode and a new JIT compiler framework, and 3.14 continues building on that performance trajectory. Python is no longer just a scripting language or a data science tool it is a serious production-grade backend language.
The three frameworks that matter most for Python web development are distinct enough to require honest framework selection rather than a default:
2+ Experience Years
Works on clearly scoped feature additions to existing Python applications under senior oversight. Understands Python fundamentals, basic Django or Flask conventions, simple ORM queries, and form handling. Writes readable code against a defined specification within an established project structure. Not suited for architecture decisions, performance investigations, or working on a greenfield application without close guidance.
5+ Experience Years
Owns complete Python features independently, from database model design through to view logic and API endpoint. Proficient in Django or FastAPI, Django REST Framework or FastAPI's validation layer, SQL query optimisation, Celery for background tasks, and basic caching with Redis. Writes tests for the code produced. Works independently on mid-complexity Python web applications and integration projects with appropriate judgement about framework and library selection.
7+ Experience Years
Architects Python applications for long-term maintainability and production scale. Deep knowledge of Django's internals, FastAPI's async patterns, database performance tuning, caching strategies, deployment with Docker and cloud infrastructure, and the testing discipline required to keep a large Python codebase reliable. Makes the architectural decisions that determine whether a Python application stays manageable three years after launch or becomes a liability requiring a rewrite.
5+ Experience Years
A Python developer assigned consistently to your web application on a retainer basis. Builds institutional knowledge of the codebase over time, understands why each part of the application was built the way it was, and develops new features faster and more accurately as the engagement progresses. The dedicated model is most effective for Python applications with an ongoing development backlog where briefing a new developer repeatedly is inefficient and introduces risk.
5+ Experience Years
Combines strong Python backend skills with Django, FastAPI, or Flask, and frontend proficiency in JavaScript, HTML, CSS, and typically React or Vue.js. Builds complete web applications where backend and frontend are developed by the same person or under unified technical direction. Reduces the coordination overhead between separate backend and frontend teams on applications where the two layers are tightly coupled.
4+ Mixed levels
For larger Python projects requiring multiple developers working as a coordinated team. We assemble Python development teams covering backend Python, frontend JavaScript, database work, and technical leadership. Our Python development company service for agencies means the team operates fully under your brand, attending your client calls and producing deliverables in your name with no reference to KiwiCommerce.
Django, FastAPI, and Flask are not interchangeable. Choosing the wrong one for a project adds weeks of unnecessary work and produces an application that fights its own framework. Our Python developers select the framework that fits the specific project requirements: Django for complex content-driven applications and eCommerce backends, FastAPI for high-throughput API and AI integration work, and Flask for lightweight services and microservices.
Every Python developer on your project is based in the UK. Feedback cycles, code reviews, architectural decisions, and urgent questions all happen within working hours. For Python web application and API projects where requirements evolve regularly, timezone availability is a delivery condition rather than a preference.
Our background in eCommerce development means our Python developers understand the specific challenges of product catalogues, order workflows, payment gateway integration, and inventory management from experience not from reading documentation. When they build Python eCommerce backends, that domain knowledge shapes decisions that a generic Python house without eCommerce depth would miss.
Python 3.14 (released October 2025, supported through October 2030) and Python 3.13 (released October 2024, supported through October 2029) are the current recommended production versions. Python 3.9 reached end of life in October 2025. Python 3.10 reaches end of life in October 2026. Our Python developers work on supported versions and handle version upgrades, including dependency compatibility validation and test coverage verification.
Your application code, data models, business logic, and commercial plans remain private. Non-disclosure agreements are signed as standard on every Python development project, dedicated retainer, and Python development team arrangement. For agencies using us as a Python development company for client accounts, we operate fully under your brand.
Some Python projects need a single dedicated Python web developer on a monthly retainer. Others need a Python development team for a defined build phase. Some need expert Python development services for a specific problem an API upgrade, a version migration, or a performance investigation on a live Django application. We structure the engagement around what the project actually requires.
From first contact to a Python developer or Python development team working on your project, the process is straightforward and starts with understanding what the application actually needs to do.
Tell us about the Python project or application. The type of work needed is new build, ongoing development, API, legacy upgrade, eCommerce backend, or data integration. The current state of any existing codebase, the Python version and framework in use or planned, and the timeline. The more context you give, the more accurately we can assess the right developer and engagement model. We respond within one business day.
For projects involving an existing Python application, our developer reviews the current codebase before agreeing on a final scope. This covers the Python version (and whether it is approaching or past end of life), the framework and its version, test coverage, database structure, migration state, dependency health, and existing technical debt. For new Python builds, we carry out a requirements discussion to define the architecture, data model, and integration points before committing to a development approach.
Based on your project, Django web app, FastAPI backend, Flask microservice, full-stack Python build, eCommerce backend, or dedicated Python developer retainer we identify the most suitable developer or team from our team. You find out who they are and can review their relevant experience before work starts. If you would like to speak with the developer first, we can arrange that.
Python development work proceeds in clear, documented stages with a staging environment for review before anything reaches production. For dedicated Python developer retainers, the developer works from a maintained backlog with regular progress updates. For project-based Python development, each milestone is reviewed and approved before the next begins. All code is committed to version control throughout, with documentation maintained alongside it.
At the conclusion of a project phase, we produce technical documentation covering the Django or FastAPI application architecture, data model, deployment configuration, and the knowledge a future developer needs to work on the Python codebase productively. For ongoing engagements, the same dedicated Python developer continues as the technical lead. We also provide Python development services on a retainer basis for applications needing consistent, knowledgeable ongoing support and feature development.

Python is a general-purpose programming language that covers web development, REST API development, data science, automation, and AI integration within the same ecosystem. A Python web developer builds web applications using Django, FastAPI, or Flask, each suited to different project types and sizes. Python is the right choice when a project requires a full-featured web framework with strong ORM and authentication (Django), a high-performance async API layer especially for AI or data integration (FastAPI), a lightweight application or microservice with maximum architectural freedom (Flask), or a backend language that connects cleanly to data science libraries like NumPy, pandas, and scikit-learn.
It is not the right primary choice for applications requiring maximum raw execution speed (where Go or C++ would be preferred), or for projects where the team has deep existing expertise in another backend language, and Python brings no specific advantage. We will tell you honestly if another language or platform is a better fit for your project.
The currently recommended production versions are Python 3.13 (released October 2024, supported through October 2029) and Python 3.14 (released October 2025, supported through October 2030). Python 3.12 and 3.11 are in security-only support and remain acceptable for production, but should be targeted for upgrade on any significant new development. Python 3.9 reached end of life in October 2025 and no longer receives any patches. Applications on Python 3.9 are carrying known, unpatched vulnerabilities. Python 3.10 enters end-of-life in October 2026 and is currently in security-only mode. If your application is on Python 3.9 or 3.10, a version upgrade should be treated as a priority task.
Django is a full-stack web framework with an ORM, admin panel, authentication system, templating engine, and security protections built in. It follows a “batteries-included” philosophy that speeds up building complex applications because most common requirements are already solved within the framework. Its size and structure make it the right choice for content-driven platforms, eCommerce backends, and applications with significant admin or content management requirements.
FastAPI is a modern, async-native web framework built on Pydantic and Starlette. It is type-hint-driven, generates automatic API documentation, and handles concurrent requests efficiently using Python’s async capabilities. It is the fastest-growing Python web framework in 2025 and the correct choice for high-throughput REST APIs, AI and machine learning integration layers, and any application where async performance and automatic validation matter. Used in production by Uber, Microsoft, and Cisco.
Flask is a micro-framework that provides routing and WSGI utilities without imposing application structure. Developers choose Flask when they want to assemble a minimal application from specific libraries rather than accepting a framework’s opinions. It suits smaller applications, lightweight APIs, and microservices. The trade-off is that large Flask applications require more discipline to keep organised as they grow.
Yes to both. For applications with ongoing Python development needs, we provide a dedicated Python developer on a monthly retainer. The same developer works on your application consistently, building knowledge of the codebase and making decisions with context. For larger projects requiring multiple Python developers working together, we provide Python development teams covering backend development, frontend integration, database work, and technical leadership. Our Python development services for agencies can be delivered under your brand through a white-label arrangement.
Yes. Our eCommerce development background gives us a genuine advantage here. A Python developer without eCommerce experience building a product catalogue or order management system will make assumptions that experienced eCommerce developers would not make about data structures, stock states, pricing logic, and payment flow edge cases. Our Python developers have built and integrated custom eCommerce backends and have worked extensively with Shopify, Magento, and WooCommerce on the platform side. That combined knowledge produces more reliable decisions at the architecture stage.
Yes. All of our Python developers are UK-based and work remotely as a standard arrangement. Remote Python development works reliably with Git version control, a staging environment for review before production deployments, agreed project management tooling for task tracking, and regular communication checkpoints that keep progress visible and feedback loops short. We structure remote Python developer engagements from the start rather than leaving communication to chance.
Yes. We handle Python version upgrades from Python 3.9 (EOL October 2025) and Python 3.10 (EOL October 2026) to Python 3.12, 3.13, or 3.14. Before starting, we audit the existing codebase, assess the Python version-specific deprecations that affect your application, check third-party library compatibility with the target version, and agree on a testing plan to validate the upgrade before it goes to production. We also upgrade Django and FastAPI to the current major versions as part of the same process, where needed.
Our UK-based Python development team is ready to look at your project. Whether you need a dedicated Python web developer on a retainer, a Python development team for a new Django or FastAPI build, expert Python development services for a version upgrade, or a full-stack Python developer for an end-to-end project, get in touch today. We respond within one business day.
