FastAPI back ends
Typed APIs with Pydantic 2 validation, running on Python 3.13.
Backend and AI
Python development services for APIs, data and telemetry
FastAPI back ends, geospatial data and device feeds. Our fleet platform runs on Python 3.13 with PostgreSQL, Redis and MQTT, and 38 drivers were on it by week three.

What we build
What we build with Python
Geospatial data
PostGIS for stops, legs and geofences. One route fell from 112 km to 97 km.
Sync queues and live updates
Redis carries the sync queue and fans out live updates.
Telematics ingest
MQTT position and engine data, normalised before storage.

When Python is the right call
Pick Python when
- The back end mixes APIs with geospatial, telemetry or data work
- You expect machine learning or computer vision later
- You want typed request validation with little boilerplate
Look elsewhere when
- An established Java or .NET back end serves you and has no data workload
- The product is a front end with a thin API
- You need Django and want a published Django build to inspect
Related: React, iOS, .NET, our AI and ML development service, and the logistics sector.

What buyers ask first
Which Python version should a new project use?
Python 3.14 or 3.13. Python 3.10 reached end of life on 1 October 2026, and each release is supported for five years from its first release.
FastAPI or Django?
Our published build uses FastAPI. We have no published Django build, and we say so on the first call.
Do you build AI and ML systems in Python?
Our tooling list covers scikit-learn, PyTorch, TensorFlow and OpenCV. Our published Python build is the TruckFleet back end, so we show that and say plainly where proof is thin.
Who owns the code and the cloud accounts?
You do, from the first commit. Repositories and cloud accounts stay in your name.
