Systems that compound in value
Every platform we deliver is designed so the tenth year of operation is cheaper and safer than the first.
Munich · Est. 2014 · Engineering-led
We build the digital infrastructure that modern organisations run on.
FER Fitness GmbH designs, engineers and operates software platforms, cloud environments and security programmes. Precision architecture, measurable performance, uncompromising reliability.

Vision & Mission
Engineering that outlives the trend cycle.
Our mission is to remove fragility from business-critical technology. We treat architecture as a long-term asset, not a quarterly experiment.
Reduce operational entropy
We replace undocumented, manual and brittle processes with automated, observable and reversible ones.
Evidence over opinion
Architecture decisions are recorded, benchmarked and revisited against production telemetry.
Core Expertise
Six disciplines, one delivery organisation.
Cross-functional squads combine engineering, cloud, security and operations so responsibility is never fragmented across vendors.
Software Engineering
Product platforms, distributed backends and design systems built with typed, testable and observable codebases.
Cloud Solutions
Multi-region cloud architecture, containerised workloads and cost-governed infrastructure as code.
IT Consulting
Technology due diligence, architecture reviews and modernisation roadmaps grounded in measurable outcomes.
Cybersecurity
Threat modelling, zero-trust identity, secure SDLC and continuous vulnerability management.
Infrastructure Management
24/7 monitoring, SRE practice, capacity planning and automated recovery for mission-critical estates.
Data & Automation
Event pipelines, warehouse modelling and workflow automation that turn operational data into decisions.
Technology Stack
A deliberately narrow toolbox.

Process Workflow
Five phases from unknown to operated.
Discovery & Audit
We map systems, constraints and risk before proposing a single line of architecture.
Architecture Blueprint
Reference architecture, security posture and delivery plan documented and agreed.
Iterative Delivery
Two-week increments with automated pipelines, review gates and shipped value each cycle.
Hardening
Load, chaos and penetration testing before production exposure.
Operate & Evolve
SLO-driven operations, incident review culture and continuous optimisation.
Why Choose Us
Accountability that does not end at handover.
We stay attached to outcomes: uptime, latency, cost per transaction and security posture are contractual, not aspirational.
Senior-only delivery
No pyramid staffing. Every squad member has shipped and operated production systems.
Transparent economics
Fixed-scope discovery, open backlog and cloud spend reported alongside engineering effort.
Documented by default
Architecture decision records, runbooks and diagrams are delivery artefacts, not afterthoughts.
Exit-ready
You own the repositories, the pipelines and the knowledge. Lock-in is never a commercial strategy.
Industry Impact
Where our systems operate.
Regulated transaction platforms
Ledger integrity, audit trails and sub-second settlement reporting under strict compliance regimes.
Connected device ecosystems
Mobile applications, telemetry ingestion and privacy-first data handling for consumer wellbeing products.
Real-time orchestration
Event-driven routing, fleet telemetry and predictive capacity planning across distributed depots.
Industrial data platforms
Edge collection, anomaly detection and maintenance scheduling built on open protocols.
Resilient citizen services
Accessible interfaces, sovereign hosting and rigorous accessibility and retention standards.
High-traffic commerce
Peak-season scaling, cache strategy and inventory consistency across channels.
Innovations
Research that reaches production.
Autonomous remediation
Policy-driven agents that detect, isolate and roll back degraded services before user impact.
Confidential computing
Workload isolation and encrypted memory enclaves for regulated data processing.
Green infrastructure
Carbon-aware scheduling that shifts batch workloads to low-intensity grid windows.
Semantic observability
Trace correlation models that translate telemetry into business-level impact statements.
