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

- Developed RESTful APIs and secure backend services to support AI-driven interactions and business processes
Hans R.
Last position:
Founder at N+One
Building an AI-native coaching platform for cyclists: a conversational Dynamic Coach that turns training and recovery data into the next session decision, available daily instead of a static calendar.
Designed and shipped a full-stack, chat-first coaching experience on Next.js and the Vercel Edge Network, with agentic workflows that adapt plans in real time to readiness, load, and life constraints.
Built integrations with Garmin, Strava, Whoop, and intervals.icu so sleep, HRV, and ride data feed coaching recommendations without manual data entry.
Product thesis: make high-quality coaching principles accessible at scale by combining adaptive training logic with plain-language conversation, not another metrics dashboard.

About the role
What they design
A software architect turns product goals into a system that teams can build, scale, and maintain. They define structure, services, interfaces, data flows, and quality standards. Common deliverables include:
- application and platform architecture
- API and integration concepts
- cloud and deployment patterns
- technical decision records
- review notes for engineering teams
Where they add value
Companies bring in a software architect when a product is growing fast, a legacy system needs a rewrite, or several teams must work on one shared platform. They are useful before a major release, during a cloud migration, or when service boundaries and ownership are unclear. In Cologne, this often fits companies in logistics, media, insurance, retail, and enterprise software that need clean coordination between business, engineering, and operations.
Core skills
A strong Software Architect balances design with delivery. They know how to simplify complexity without creating hidden risk. They work well with engineers, product owners, and operations teams.
- system design and domain modeling
- microservices, modular monoliths, and event-driven patterns
- API design and integration planning
- cloud platforms and container-based delivery
- security, reliability, and maintainability
Tools and methods
The work often starts with workshops, whiteboards, and architecture reviews. Architects document decisions clearly and keep them tied to business goals. Typical tools and methods include UML or lightweight diagrams, ADRs, C4-style views, code review input, observability concepts, and collaboration in Jira, Confluence, and common cloud stacks.
What strong architects do
Great software architects do not only draw diagrams. They ask the right questions, challenge weak assumptions, and help teams avoid overengineering. They understand trade-offs between speed, cost, scalability, and long-term support. They also explain complex topics in plain English, which is important when Cologne-based teams mix local staff with remote engineers or external freelancers.
When freelance makes sense
Freelance support works well when you need senior judgment for a defined scope, not a permanent layer of management. It is a good fit for architecture assessments, rescue projects, greenfield design, platform refactoring, or short advisory work during delivery spikes. For companies that need an experienced software architect without a long hiring cycle, an external specialist can start with a clear mandate and focus on the highest-risk decisions.
Frequently asked questions
What clients ask us most about Software Architects — answered in short.
A Software Architect defines how the system should be structured, how parts communicate, and which standards the team should follow. On a freelance project, that often means architecture assessments, target-state design, API planning, and support for implementation teams. The role is practical: it should remove ambiguity and keep delivery aligned with business goals.
Look for strong system design skills, clear thinking, and experience with modern delivery setups. A good software architect understands cloud environments, integration patterns, data flow, security basics, and how to document decisions without slowing the team down. Communication matters just as much as technical depth.
A senior developer usually focuses on building complex parts of the codebase, while a tech lead helps guide a team day to day. A software architect works at a broader level and shapes the technical direction across teams, services, and platforms. In some companies the titles overlap, but the scope is usually wider for the architect role.
Freelance support makes sense when the need is tied to a project, a redesign, or a critical decision period. If you need an architecture review, a cloud migration plan, or help untangling a legacy system, a freelancer can step in quickly and stay focused on the target. A permanent hire is better when the work is continuous and part of core leadership.
Yes, most of the work can be done remotely if the team has good access to diagrams, repositories, and decision records. For Cologne-based companies, a mix of remote work and on-site workshops often works best, especially at the start of the engagement. In-person sessions are useful for stakeholder alignment, whiteboarding, and difficult trade-off discussions.
Common topics include microservices, modular monoliths, event-driven design, APIs, cloud platforms, and containerized deployments. Depending on the stack, a software architect may also work with Java, .NET, JavaScript backends, or data-heavy platforms. The exact tools matter less than the ability to choose a fit-for-purpose structure.
Judge the quality by the clarity of the decisions and the effect on delivery. Strong work leaves the team with a direction they can build, clear trade-offs, and fewer recurring technical disputes. Good architecture also shows up in maintainable code, stable interfaces, and fewer surprises during implementation.
Freelance software architects are usually brought in for a defined problem, not open-ended supervision. Expect to work with product, engineering, and sometimes operations or security teams, and to explain choices in a way that supports execution. Clear scope, quick context access, and direct communication are key to doing the job well.
