Simplicity is a security control
Complex systems fail in ways nobody predicted. We remove components before we add them, and we justify every dependency we keep.
About Us
An engineering company that stays long after the launch.
FER Fitness GmbH was founded in Munich in 2014 by a group of platform engineers who were tired of watching well-funded systems fail for structural reasons. Today we are a distributed team of specialists in software engineering, cloud architecture, security and operations.
Background
Eleven years of production responsibility.
What began as a three-person consultancy rebuilding a failing payments backend now operates platforms across six industries and four cloud regions.
2014
Founded in Munich as a platform remediation consultancy.
2017
First managed cloud practice; Kubernetes adopted as standard.
2021
Dedicated security engineering division established.
2025
Autonomous remediation research programme moves to production.
Philosophy
Four convictions we do not negotiate.
Ownership cannot be outsourced
Teams that build a system operate it. Pager duty stays with the people who make architectural decisions.
Documentation is part of the product
A platform nobody else can operate is unfinished. Runbooks, diagrams and decision records ship with the code.
Measure or do not claim
Performance, reliability and cost improvements are reported from telemetry, never from narrative.
Execution Framework
How work actually moves through the organisation.
Autonomous squads
Four to seven engineers with an architect, an SRE and a security lead attached. One squad, one accountable outcome.
Two-week increments
Every increment ends with deployable software, updated documentation and a measured delta against agreed indicators.
Automated before manual
Static analysis, dependency scanning, contract tests and load baselines run on every commit; human review focuses on design.
Architecture decision records
Every significant choice is written down with context, alternatives and consequences, and revisited quarterly.
SLO-driven service management
Error budgets determine whether a squad ships features or stability work in the next increment.
Blameless incident review
Every incident produces systemic corrective actions tracked in the same backlog as feature work.
Technological Commitment
Standards we hold ourselves to.
Our internal engineering standard is published to clients at the start of every engagement and audited annually.
Infrastructure as code
No manual production change. Every environment is reproducible from version control within one hour.
Zero-trust identity
Short-lived credentials, workload identity and least-privilege policy enforced across all environments.
Supply chain integrity
Signed artefacts, SBOM generation and pinned dependencies for every release we deliver.
Data minimisation
We collect the least data required, retain it for the shortest defensible period and encrypt it in transit and at rest.
Accessibility
Interfaces are built and tested against WCAG 2.2 AA as a delivery requirement.
Sustainability
Workload placement and scheduling account for energy intensity as well as cost and latency.
Corporate Details
Transparency on who we are.
