Custom software for technically demanding systems
Architecture, development and quality assurance in one team, for systems where downtime gets expensive. Industrial automation, energy, telecommunications, medical technology.
Technology fields
The core promise
At a software company of this size, independent QA competence is rare. Usually developers test their own code, or the client takes on acceptance testing. At AereA, an ISTQB-certified test manager owns quality assurance from the management level. That is why the systems keep running after handover.
01
Test-driven development as a binding team standard, tests as a mandatory gate in CI, end-to-end tests against genuinely running APIs with a real database instead of against mocks.
02
We have owned Phonalisa architecturally since the day we founded the company, 17 years now, developing, testing and documenting it throughout. At the same industrial client, the data platform was followed by the migration of the condition monitoring backend.
03
Medical technology in an approval-relevant setting, tax software for a state finance authority with accessibility and GDPR testing, vehicle bus analysis at a premium manufacturer, energy infrastructure in the field.
On the subject of AI
Agent-assisted development runs inside defined guardrails, with human sign-off for architecture, security and release. The capacity we free up goes into test depth, not into more features.
Project report: energy, IIoT, e-mobility
Inverters, battery storage, wallboxes and meters come together in a shared time series base. On that basis the platform decides automatically about charging, discharging and shifting flexible loads, operated by us, with observability across the whole path.
Starting point
Heterogeneous energy and charging infrastructure without a shared data base: every manufacturer with its own interface, no reliable basis for load decisions.
Approach
Five cleanly separated processing stages: edge connectivity, ingest via MQTT and Kafka, state projection into TimescaleDB, versioned REST API with live stream, Angular interface.
Result
Price- and CO₂-optimised charging and storage based on day-ahead prices from European bidding zones, with automated load shifting and storage control.
Services
Each cluster with its own page: what we actually do, when we are the wrong supplier, collaboration models, typical project size and a named contact.
Industries
Six fields in which we know the constraints: approval, protocols, service life and legacy estate.
How we work
Our playbook is public: what a quality gate looks like here, what an agent may and may not do, how we cut an arc42 document.
