How our development runs
We work on the principle of scrum – on a weekly basis we groom tasks, do a review of the previous sprint, plan the next steps, and do retrospective analyses.
We develop our own product, so you will never jump from one project to a completely unrelated one here. We always consider the future, so we take long-term sustainability into account. We try to minimize technical debt so the SOLID and DRY principles are our friends.
We started as a lean startup, so we aren’t going to sugarcoat our design and say that each line of code is exactly according to our current ideas. Sometimes, you may come across a bit of legacy code, and when we decide that it’s necessary to make fundamental changes, we always prefer refactoring and occasionally rewriting a feature.
For new modules, however, we try to do our refactoring as soon as we develop something that requires it – usually a new client request or knowledge we gained during our event storming sessions (and thanks to the application Miro, it’s also remote!).

What else can you get from us besides PHP? We have several
modules running on Node.js / TypeScript, while in others we
use Firebase or Vue.js on the front end. We have room for
testing new technologies and providing further development,
both from our experienced team and through a budget for
What we do at Spaceflow
Spaceflow increases comfort in buildings by connecting
owners, tenants, visitors, and service providers through a
community platform – a mobile application. Various activities,
sharing, local services, and connections with other people are
all features that we create. Spaceflow also serves as a platform
for IoT and other smart building integrations. Find out more
about our mission at Techcrunch.
What you should already know
and what technologies we use
- Our REST API uses Symfony 4.3 and 5.1, Doctrine, PHP
7.3 and 7.4, MySQL, ElasticSearch, and RabbitMQ – we
don’t need you to recite 20 lines of DQL from memory, but
we do need you to have an in-depth understanding of the
concepts behind these technologies.
- We use Gitlab for code versioning, where CI – unit tests,
integration tests, ECS, or PHPStan also run. Thanks to
this, we are not afraid to change and constantly improve
the current code according to new requirements.
- Our infrastructure is, of course, in Docker. It is currently
running on Google Cloud, but moving to orchestration
- You should be able to read the technical documentation
and write on Slack in English.

- We implement new services in a clean repository as
separate modules in which the business language
- You can only talk to our new model from the outside
through commands, events, and queries. #cqrs
- We store domain entities as event streams, from which we
then create a read projection model. #eventsourcing
- We automatically generate from our tests human-readable
documentation of stories and scenarios for the backend
