01 · Services

Everything between the idea and a running system.

You don’t get a partial deliverable that stalls at the next interface. We take responsibility for code, infrastructure and operability – individually or as a complete package.

/01

Web & software development

Backends, APIs and web frontends that stay maintainable: cleanly structured, tested and built for operations from day one.

  • REST APIs and microservices with clear contracts
  • Web and hybrid apps for business users and customers
  • Clean code, automated tests, code reviews
  • Java / Spring Boot
  • C# / ASP.NET Core
  • Python / FastAPI
  • TypeScript / Node / NestJS
  • Angular
  • Vue
  • Ionic
/02

DevOps & CI/CD

From commit to production without manual steps: reproducible builds, verified artifacts and deployments you can roll back through Git.

  • Build, test and release pipelines
  • GitOps with Argo CD (app-of-apps, dev/staging/prod)
  • Artifact management with security scanning, SVN → Git migration
  • GitLab CI
  • Jenkins
  • Azure DevOps
  • Argo CD
  • Artifactory
  • Xray
/03

Kubernetes & platform engineering

Internal platforms where teams ship on their own – with standards for networking, certificates, access and lifecycle.

  • OpenShift
  • AKS
  • EKS
  • Helm
  • Operators / CRDs
  • Istio
/04

Cloud & infrastructure as code

Infrastructure as versioned code: environments you can rebuild identically at any time – in the public cloud or your own data centre.

  • AWS
  • Azure
  • OpenStack
  • Terraform
  • Ansible
/05

Architecture & modernisation

Assessment, target architecture and a migration path that doesn’t put running operations at risk – from monolith to microservices.

  • Microservices
  • Enterprise architecture
  • PoCs
  • Tool evaluation
/06

Security & compliance

Security as part of the architecture, not a hurdle at sign-off. Proven in environments with strict requirements and audits.

  • Central identity and access integration
  • Secure SDLC: scanning, signing, traceable approvals
  • Security concepts and ITIL processes for regulated environments
  • IAM
  • LDAP
  • OAuth2
  • OIDC
  • Secure SDLC
/07

AI & agents

Internal AI assistants and agents running on your own infrastructure – your data stays in-house.

  • Local language models instead of external AI services
  • Agents that reach internal systems through your own APIs
  • Tracing and quality measurement for every answer
  • Ollama
  • Langfuse
  • FastAPI
  • Python

Training & workshops

Knowledge stays in-house: we train your team in the technologies we introduce – from GitOps and Kubernetes to infrastructure as code. On site or remote, tailored to your environment.

02 · Why Team Codex

One partner. Full ownership.

At Team Codex there is no sales layer and no rotating staff. You talk directly to the people who design, build and run your system – and who stand behind it.

Our standard: a project is only done when it runs reliably and your team can carry it forward on its own. // our standard

  • 10+

    Years of project experience

    More than ten years in software development, DevOps and cloud – from start-up to financial institution.

  • E2E

    End-to-end ownership

    Requirements, architecture, code, pipeline, platform and operations from a single source. No gaps between trades.

  • // regulated

    Highly regulated environments

    Banks, a central bank, federal authorities and defence: security requirements, audits and approval processes are business as usual for us.

  • // direct

    Short paths

    One dedicated contact from the first analysis to handover. Decisions are made without detours.

  • // docs

    Documentation & knowledge transfer

    Architecture decisions, runbooks and handovers are part of the deliverable. No knowledge gets stuck with us.

  • // remote-first

    Remote-first, across DACH

    Based in Dortmund, working on projects in Germany, Austria and Switzerland. On site when the work calls for it.

  • 3

    Project languages

  • // neutral

    Tools chosen by requirements

    Technologies are assessed and selected against transparent criteria – not out of habit.

04 · Process

Four steps. One result that runs.

Transparent from the start: in every phase you know what will be delivered, and after each step you decide how to proceed.

  1. 01

    Analysis

    Capture goals, current state, dependencies and risks. We agree on what success concretely means.

    Output: requirements, prioritised backlog, effort estimate

  2. 02

    Concept & architecture

    Target architecture and technology choices with documented reasoning – validated by a PoC where needed.

    Output: target picture, architecture decisions, PoC

  3. 03

    Delivery

    Iterative development in short cycles, with pipelines and infrastructure as code from day one.

    Output: working increments, tests, CI/CD, IaC

  4. 04

    Operations & handover

    Set up monitoring, alerting and runbooks, onboard your team and hand over cleanly – or keep supporting you.

    Output: stable operations, documentation, know-how in your team
