Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

Marc S.
Last position:
Fullstack Developer at PLANT-MY-TREE
PLANT-MY-TREE®-per-order
The application enables Shopify merchants to automatically place tree-planting orders for every incoming order. By integrating ecological contributions directly into the purchase process, the manual effort for tracking and billing reforestation initiatives is eliminated. The system increases transparency for end customers through real-time visualizations of the ecological impact directly in the storefront. The architecture is based on a modular monolith with Spring Boot in the backend and an integrated React app inside the Shopify admin area. The solution uses webhooks to capture order data in an event-driven way and integrates the weclapp ERP system for automated monthly invoicing. An app proxy mechanism provides dynamic statistics such as CO2 compensation and planted trees without any performance loss for the merchant shop.
Tasks:
- Design of the modular software architecture based on Spring Modulith to ensure high maintainability
- Development of the event-driven business logic for evaluating Shopify orders via webhooks
- Implementation of automated invoicing by connecting the weclapp REST API
- Building the frontend using React Router and Shopify App Bridge for native integration
- Design of the database model and implementation of the persistence layer with JPA/Hibernate and Prisma

About the technology
What CI/CD does
CI/CD, short for continuous integration and continuous delivery or deployment, automates the path from a code change to a tested release. It connects source control, builds, automated tests, security checks, artifact storage and deployment so teams can deliver software with repeatable steps and clear feedback.
Where it is used
CI/CD supports web applications, APIs, mobile backends, data services and internal business software. It can also coordinate infrastructure changes and releases across development, staging and production environments.
- Compile and test every change
- Package container images and application artifacts
- Promote releases through controlled environments
- Roll back failed deployments safely
Tools and ecosystem
Strong specialists work across pipeline configuration, Git workflows and release governance. Common ecosystems include GitHub Actions, GitLab CI/CD, Jenkins, Azure Pipelines, CircleCI, Argo CD and Tekton, often combined with Docker, Kubernetes, Terraform and cloud services. Observability, secrets management and software supply-chain security are part of reliable delivery.
When companies need help
Freelance expertise is useful when a team is replacing manual releases, standardising pipelines across repositories or moving workloads to the cloud. It also helps when builds are slow, deployments are fragile, test coverage is unclear or several teams need a shared delivery model.
- Design pipeline stages and approval rules
- Connect tests, scanners, registries and deployment targets
- Improve failed-build feedback and release traceability
- Document workflows for internal teams
Working across Cologne teams
A CI/CD specialist can support local product groups, industrial companies, media organisations and software teams in Cologne, whether collaboration is on site, remote or hybrid. The work often spans time zones and several disciplines, so clear documentation, working English and reliable communication matter alongside technical delivery.
What good specialists deliver
Look for evidence of maintainable pipelines rather than a list of tools. Strong professionals define secure, reproducible workflows, keep credentials out of source code, make tests and deployment rules visible, and measure delivery health without creating unnecessary process. They explain trade-offs between continuous delivery and automatic deployment, adapt to existing architecture and leave the team with usable documentation and ownership.
Frequently asked questions
Key details about CI/CD, drawn from the questions we get asked most.
CI/CD is used to automate software integration, testing, packaging and release activities. Continuous integration validates code changes frequently, while continuous delivery prepares releases for controlled deployment and continuous deployment can release approved changes automatically.
CI/CD replaces manual, infrequent handovers with repeatable pipeline steps and fast feedback. A traditional process may still work for simple systems, but automated checks and controlled promotion reduce avoidable release errors as software and teams become more complex.
A strong CI/CD specialist may work with GitHub Actions, GitLab CI/CD, Jenkins, Azure Pipelines or CircleCI. Useful adjacent skills include Docker, Kubernetes, Terraform, cloud services, artifact repositories, automated testing, secrets management and observability.
Continuous delivery keeps a tested release ready for a deliberate production decision. Continuous deployment goes further by releasing qualifying changes automatically, so the right choice depends on risk, test confidence, approval requirements and the organisation’s operating model.
The required CI/CD experience depends on system complexity, compliance needs, deployment targets and the condition of existing pipelines. A simple workflow may need focused setup, while a multi-environment platform usually requires expertise in architecture, security, troubleshooting and team enablement.
CI/CD is well suited to remote and hybrid collaboration because pipeline definitions, logs, reviews and deployment records are shared digitally. Teams in Cologne should agree on communication routines, access controls, documentation standards and language expectations before work begins.
Ask a CI/CD freelancer to explain how they handle failed builds, flaky tests, secrets, rollbacks and production approvals. Look for clear reasoning, secure defaults, readable configuration, useful documentation and examples of improving reliability without adding needless complexity.
A practical CI/CD engagement should leave behind versioned pipeline configuration, connected tests, secure credentials handling, deployment documentation and a clear operating process. It may also include reusable templates, dashboards, rollback guidance and a handover that enables the internal team to maintain the workflow.
