Backend engineering
Python & FastAPI Development
Production APIs and data services in Python: FastAPI, async SQLAlchemy, PostgreSQL, Redis and background workers, built to be tested, observed and operated.
You need a backend that will not fall over at the first real load, written by someone who has shipped async Python services with migrations, workers, auth and monitoring in place.
What you get
- Typed, documented REST APIs with OpenAPI docs
- Async PostgreSQL access with Alembic migrations
- Background jobs with Redis, Celery or Kafka
- Auth, rate limiting, caching and observability built in
Deliverables
- FastAPI service with a clean layered structure (API, core, storage, workers)
- Database schema, migrations and seed scripts
- Unit and integration test suite with CI
- Dockerfiles and Compose stack for local and production
- Runbook and handover documentation
Stack we use
Want to learn it instead? Production Python Backend Engineering with FastAPI
From requirements to production
- 01Requirements
A discovery call, then a written scope with acceptance criteria and a realistic estimate.
- 02Design
Architecture, data model and API contracts agreed before code is written.
- 03Build
Short iterations with demos; code reviewed, typed and documented as we go.
- 04Test
Unit, integration and end-to-end tests; QA passes against the acceptance criteria.
- 05Deploy
Docker, CI/CD and cloud setup with monitoring, then a production handover.
- 06Support
Production bug fixing, performance tuning and improvements after launch.
Ways to work together
Fixed-scope project
A written scope, milestones and a fixed price. Best for a defined feature, integration, migration or redesign.
Monthly retainer
Reserved engineering hours every month for ongoing development, maintenance and production support.
Hourly & advisory
Architecture reviews, code reviews, pairing sessions and second opinions, billed by the hour.

W3Colleges: a full redesign that kept every URL
This site is our own case study: a new design system, article reader, listing pages, search, login, hub pages and a CI/CD pipeline, delivered as a child theme without touching WordPress core, while 400+ articles, their URLs and SEO metadata stayed intact.
Questions
Can you take over an existing codebase?
Yes. We start with a review of the code, tests and deployment, then agree what to stabilise first.
Do you work with Django or Flask too?
Yes, though FastAPI is our default for new services. We are comfortable maintaining Django and Flask applications.
How do you handle code ownership?
Everything lives in your repository from day one. You own the code and the infrastructure accounts.
