Python agency for applications, data and AI

We build FastAPI APIs, Django applications and Python pipelines that connect your data, tools and workflows, from discovery to production.

Services

What our Python agency builds

Not promises. Results.

Production AI and machine learning

We integrate predictive models, semantic search and LLM features into your tools, with evaluation, monitoring and control over the data sent to models.

Python takeover and modernisation

Code audit, version migration, typing and tests, workload optimisation and containerisation: we improve an existing Python codebase in controlled stages.

Data pipelines and automation

Multi-source ingestion, cleaning, transformation and reporting: we automate data flows with Python, Polars or Pandas and orchestration suited to their frequency.

FastAPI APIs and Django applications

We design documented APIs with FastAPI and Pydantic, or Django business applications with administration, authentication and structured business rules.

A Python project to scope?

API, business application, data or AI: share your context so we can identify a useful and realistic first step.

Objective

Why choose Python for your project?

1

One language for web, data and AI

Python can power the backend, data processing and artificial intelligence features within one coherent ecosystem. Exchanges between teams and components are easier to maintain.

2

FastAPI or Django based on the product

FastAPI suits APIs and asynchronous services with Pydantic validation and OpenAPI documentation. Django provides a complete framework for business applications with ORM, administration and authentication.

3

A proven data ecosystem

Polars, Pandas, scikit-learn, PyTorch and orchestration tools cover the chain from ingestion to delivering a model or business metric.

4

Performance that is designed

Async for I/O, task queues for long-running work and optimised libraries for computation: the architecture is selected according to measured load and product constraints.

Maintenance

From Python prototype to operable service

A notebook or script validates an idea. To run reliably in production, code, data and operations must be structured together.

Quality and maintainability

Types, Pytest tests, Ruff linting and locked dependencies make changes safer and simplify handover to another team.

Load and processing

We separate requests, asynchronous tasks and intensive computation, then measure latency, memory and volumes before targeting optimisations.

Deployment and monitoring

Docker, continuous integration, logs, metrics and alerts provide reproducible deployments and make incidents observable.

Interfaces

Which Python foundation should you choose?

FastAPI and Pydantic

For a typed, documented and asynchronous API serving a web frontend, mobile application or other services.

Django and Django REST

For a business application that benefits from a mature ORM, integrated administration and a complete authentication system.

Polars, Celery and orchestration

For imports, transformations and long-running computations executed in the background, scheduled and monitored separately from user requests.

Services

Why entrust your Python development to PeakLab?

The need before the framework

We start with your users, data and operational constraints. Python is selected when it genuinely simplifies the product.

Web, data and AI expertise

We connect Python processing to interfaces, databases and existing tools to deliver a complete feature rather than an isolated prototype.

Verifiable code

Tests, types, reviews and regular demos make every delivery observable. Performance limits and data quality are addressed explicitly.

A transferable project

Repository, environments, architecture decisions and operating procedures are documented. You retain ownership of the code and the ability to evolve it.

What if your data became a business product?

We turn manual processing and scattered sources into a Python tool your teams can use every day.

ODD Pharma: automating data analysis with Python

PeakLab built a platform that collects, processes and presents pharmacy business data. Python automates previously manual workflows and powers a white-label business application.

Method

Our method for your Python project

Not promises. Results.

1

Scope users and data

We identify users, sources, data quality, security constraints and the metrics that will be used to assess the result.

2

Targeted prototype

We validate technical risks on a small scope: an API contract, a data sample or a measurable AI use case.

3

Industrialisation

The prototype becomes a structured service with types, tests, error handling, storage, integrations and a reproducible environment.

4

Production and monitoring

We deploy, instrument workloads and track technical performance alongside business outcomes to prioritise improvements.

FAQ

FAQ: choosing a Python agency

FastAPI is suitable for pure APIs, microservices and asynchronous processing, with Pydantic validation and OpenAPI documentation. Django works better for business applications that benefit from its ORM, administration and integrated authentication. The choice depends on the product and how it will be operated.
