Enterprise IT Consulting & Development

We design and deliver complex software architectures for business-critical platforms — from architectural decisions to production-ready implementation.

Available for projects in the DACH region and remote (EU).

What we deliver

Focused on the intersection of architecture, security, and operational excellence.

Software Architecture

Design and assessment of distributed systems, microservices architectures and enterprise platforms.

Scalability ↑ · Coupling ↓

Typical problems

  • Poorly defined service boundaries
  • Missing failure domain isolation
  • Deployment coupling between services
  • Over-fragmentation without domain boundaries
  • Shared databases across services

Principles

  • Domain-driven design as the foundation
  • Failure domain isolation as a design objective
  • Explicit data ownership per service
  • Independent deployment boundaries
  • Contract-first versioning strategy

Technical focus

  • Service decomposition and boundary definition
  • Dependency graph analysis
  • Failure propagation modelling
  • Deployment topology review
  • Communication patterns (sync/async)

When it applies

  • Monolith blocks team autonomy
  • Deployments are coupled
  • Multiple teams on one codebase
  • Diverging scaling requirements

This competency is the foundation of structured project engagements.

IT Consulting

Strategic technology consulting, feasibility studies, architecture reviews and technical leadership in critical project phases.

Risk ↓ · Decision quality ↑

Typical problems

  • Technology decisions without architectural foundation
  • No feasibility analysis before project start
  • Missing technical leadership in critical phases
  • Cost overruns due to poor planning

Principles

  • Architecture-first before implementation
  • Risk assessment in all phases
  • Independent evaluation without vendor bias
  • Clear recommendations, not option lists

Technical focus

  • Architecture review and assessment
  • Feasibility studies
  • Technical due diligence
  • Roadmap development and prioritisation

When it applies

  • Before strategic technology decisions
  • Ongoing projects in difficulty
  • Before tenders and procurement
  • M&A transactions with IT relevance

This competency is the foundation of structured project engagements.

Software Development

Implementation based on proven standards: Java, Spring Boot, Microservices, Kafka, Kubernetes — from specification to production.

Quality ↑ · Time-to-market ↓

Typical problems

  • Technical debt from fast delivery
  • Missing test strategy
  • Poor observability in production
  • Unplanned scaling problems

Principles

  • Test-driven development where appropriate
  • Clean architecture and SOLID
  • CI/CD as a prerequisite
  • Observability by design

Technical focus

  • Java / Spring Boot backend development
  • Kafka event-driven systems
  • Kubernetes-native deployments
  • API design and versioning

When it applies

  • New development of critical platforms
  • Existing systems with quality issues
  • Scaling pressure on legacy systems
  • Team extension with senior expertise

This competency is the foundation of structured project engagements.

Project Management

Technical project leadership, coordination of complex development initiatives, nearshore and offshore management.

Predictability ↑ · Risk ↓

Typical problems

  • Missing technical leadership in project management
  • Poor nearshore/offshore coordination
  • Unclear or changing requirements
  • Milestones regularly missed

Principles

  • Technical PM with architectural understanding
  • Iterative planning with clear milestones
  • Transparent risk communication
  • Stakeholder management at eye level

Technical focus

  • Technical project leadership
  • Nearshore/offshore management
  • Requirements analysis and prioritisation
  • Risk and quality management

When it applies

  • Complex multi-team projects
  • International development teams
  • Critical delivery phases
  • Project rescue situations

This competency is the foundation of structured project engagements.

Security & Identity

OIDC/OAuth2 implementations, Zero Trust architectures, tenant isolation and compliance in regulated environments.

Attack surface ↓ · Compliance ↑

Typical problems

  • JWT without key rotation
  • Missing tenant isolation
  • Incorrect OAuth2 flows
  • Token forwarding without scope validation
  • Trust boundary violations

Principles

  • Zero Trust — never implicitly trust
  • Service-to-service identity (mTLS/SPIFFE)
  • Least privilege consistently applied
  • HSM/KMS for key management

Technical focus

  • OIDC/OAuth2 token flow analysis
  • Identity provider design
  • Multi-tenant isolation
  • API security review
  • Compliance architecture (GDPR, ISO 27001)

When it applies

  • Regulated environments (GDPR, eIDAS)
  • SaaS platforms with enterprise customers
  • Before security audits
  • After security incidents

This competency is the foundation of structured project engagements.

Cloud & Modernisation

Legacy system migration, cloud-native transformation, Kubernetes deployment and incremental modernisation strategies.

Operating costs ↓ · Agility ↑

Typical problems

  • Lift & shift without cloud-native adaptation
  • Poor resource configuration (OOM, CPU throttling)
  • No GitOps, no reproducible deployments
  • Missing pod security standards

Principles

  • Cloud-native design, not lift & shift
  • Immutable infrastructure
  • GitOps as single source of truth
  • Secure-by-default deployments

Technical focus

  • Cluster design and autoscaling (HPA/VPA)
  • Deployment strategies (canary, blue/green)
  • Cost optimisation
  • Migration strategy for legacy systems

When it applies

  • Cloud migration under time pressure
  • Rapid scaling required
  • Cost optimisation pressure
  • On-premise to cloud in regulated environments

This competency is the foundation of structured project engagements.
