Structure for data, integrations and teams
When data, APIs and processes are designed to work together, complexity becomes easier to manage.
Whether you’re creating a new foundation or untangling systems that have grown over time, I help you bring structure to your digital setup. Clear architecture and reliable integrations create smoother workflows, more confident decisions and less friction.
Tools, data and processes — finally aligned
As a Solution Architect, I connect systems with a clear purpose: fewer parallel tools, fewer duplicate steps and clearer ownership. Teams find what they need faster and processes become easier to follow, run and improve.
Decisions you can trust
When integrations run reliably and migrations are done right, reporting becomes dependable. That means better planning, faster decisions and fewer debates about which number is actually correct.
Adoption that lasts
With workshops, training and clear communication, new systems become easier to understand and easier to use. That lowers resistance, reduces support effort and gives teams a calmer day-to-day experience.

Technical change management & training
Focus: Change without the frustration: handovers that help teams understand, accept and use new systems with confidence.
- Workshops and training for teams and stakeholders
- Documentation for operations, interfaces and processes, no black box
- Support during rollouts and migrations, including testing, go-live support and hypercare
- Structured planning of change requests and future development without disrupting operations
Every project starts in a different place, so I don’t offer fixed packages online. What matters to me is that scope, effort and budget are clear and fair for both sides. After a quick look at your setup, I’ll give you an honest estimate of scope, priorities and cost.
How we work together
1 | Create clarity
We start by understanding your current setup and what needs to improve.
- Starting point: what should improve, and what problem are we solving?
- Clarification: who needs what - business teams, IT, management?
- I structure requirements and translate them into plain language.
A shared understanding of the current state and a solid base for the right next steps.
2 | Plan the path
Ideas become a practical plan.
- I create a concept with options and recommendations.
- We align on priorities and refine the scope together.
- Once the concept is approved, we move into implementation.
A transparent plan that makes sense for everyone involved.
3 | Build & go live
Step-by-step implementation with useful feedback loops.
- Implementation in aligned stages - agile, but structured.
- Joint testing and review phase.
- Go-live when everything is ready.
A solution that runs reliably and is accepted by the team.
4 | Run & improve
The architecture is in place, and new requirements become manageable.
- Immediate support after go-live. (Hypercare)
- Long-term handling of change requests and new requirements.
- Clear interface and system documentation as a foundation for the team.
A system that not only works, but stays maintainable and easy to extend.
Work in
practice
Good architecture proves itself in everyday work. Here’s a look at projects where systems were consolidated, integrations stabilized and teams were supported through change.
Solid architecture needs strong roots
My career started hands-on: understanding how things are built, why they fail, and what makes them reliable. That way of thinking still shapes my work today. As a Solution Architect, I design system landscapes that are not just technically sound, but practical to run and easy for teams to work with.
Whether it’s an ERP rollout with Business Central, a Jira Cloud migration, or a move to Microsoft Teams, I don’t look at the software in isolation. I look at how people will actually use it, and what they need to feel confident with the change.

What drives me — and what
that means for you
I’m an “assertive mediator” (INFP-A). Sounds like personality-test talk, but in IT projects, it has real business value.
I translate
I speak both developer language and business language. Clear communication is where good implementation starts.
I stay calm
Migrations can get stressful. When things get stormy, I stay steady and help keep the project on course.
I create buy-in
The best software is useless if the team works around it. I meet people where they are and help them move with the change.
I build solutions that work and keep working
With technical depth, strategic perspective and a feel for people. Let’s build something that lasts.
Hey Sebi, ...
What does a Solution Architect actually do and what do we get from it?
A Solution Architect makes sure your systems fit together: technically, operationally and in everyday use.
The result is not just a nice diagram. It’s a setup that runs more smoothly, needs fewer workarounds, creates fewer questions, delivers more reliable numbers — and helps teams work with the system instead of around it.
When is api-bi.dev the right fit for us?
When complexity starts slowing you down: too many tools, integrations that “somehow” work, reporting that takes too long, or every department working with its own version of the truth.
I’m the right fit if you want both clarity and implementation and a solution that can be understood, used and maintained after the project is done.
What kind of companies do you usually work with?
Mostly mid-sized companies and growing teams that want to professionalise their IT and data landscape without overengineering it.
Often, these are companies with ERP/CRM systems, multiple business applications and reporting processes that still require too much manual work. I work remotely or on-site around Hamburg, depending on what makes sense for the project.
What concrete results can we expect after working together?
Typical outcomes are:
- Less manual work, with fewer copy-paste tasks and fewer Excel firefighting moments.
- Cleaner, more reliable processes, with integrations and data flows that are easier to understand and trust.
- More relaxed teams, with less chaos and fewer questions like “Who changed what?”
And long term: a system that can grow without having to rebuild everything from scratch.
Do you only do consulting and strategy — or also implementation?
Both.
I help define the target architecture, structure the roadmap and turn it into a working setup. That includes system integration, APIs, ETL/ELT pipelines, data migrations and automation.
For me, a solution should not stop at the concept stage. It needs to work in daily operations.
Our systems have grown over time. Does everything need to be rebuilt?
In most cases: no.
Often, the better path is clear consolidation: what stays, what goes, and what needs to be properly integrated. Sometimes that happens step by step.
The goal is not “new at any cost.” The goal is the right solution for your context — with effort, cost and risk kept under control.
Do you also support ERP projects, e.g. Microsoft Dynamics Business Central?
Yes — especially when ERP should not be treated as an isolated system, but as part of your wider system landscape.
Many problems do not happen inside the ERP itself, but around it: interfaces, data quality, processes and reporting. That’s where good architecture creates much more stability in everyday work.
Do you offer data integration, ETL and API development?
Yes. This is one of my core areas.
I make data flows stable and understandable from source to actual use. Whether it’s REST/SOAP APIs, ETL/ELT workflows or automation, the goal is always the same: data arrives reliably, is structured properly and can actually be used.
We use Jira and Confluence, but it feels chaotic. Can you help?
Yes.
Very often, the tool itself is not the problem, the setup is. Workflows, ticket structures, permissions and knowledge management all need to make sense.
I help structure, optimise or migrate Jira and Confluence setups, including cloud migrations, so teams experience less friction and collaboration becomes clearer.
How do you make sure employees actually adopt the solution?
By treating enablement as part of the work, not as an afterthought.
Clear communication, documentation, workshops, training and a solution that feels logical are all important to me. In the end, teams should not have to “cope” with the system they should understand it and feel confident using it.
How quickly can you start, and how big does a project need to be?
That depends on timing and scope.
I work on smaller, clearly defined packages, for example stabilising an integration, cleaning up Jira/Confluence or building an ETL workflowm, as well as larger transformation projects.
Once I understand your goal, system landscape and timeline, I can give you a realistic assessment.
Remote or on-site in Hamburg?
Both.
Remote works very well for most topics. For kickoffs, workshops or critical project phases, being on-site can make sense, especially around Hamburg, but also across Germany.
Is this a fit if we’re not “data-driven” yet?
Especially then.
Often, the first step is getting the basics right: connecting systems, making data reliable and stabilising processes. Once that foundation is in place, the rest becomes much easier, without overwhelming your team in day-to-day work.
What makes your work different from other freelancers in this field?
For me, a solution has to be technically solid and accepted by the people using it.
I work as a partner, at eye level. I make decisions transparent, explain the reasoning behind them and support the rollout in a way that helps your team use the system with confidence instead of feeling slowed down by it.
Which tools and technologies do you work with?
I’m tool-agnostic and choose the stack based on what your situation actually needs.
I support IT architecture and system landscapes, the introduction of central platforms such as ERP systems like Business Central, and data integration across tools and systems.
That includes APIs such as REST and SOAP, ETL workflows, data migrations and integration tools like Talend or Rundeck, including custom connectors with Java, PHP or SQL.
I also support Atlassian setups with Jira and Confluence, including server-to-cloud migrations, as well as modern workplace topics with Microsoft Teams and VoIP.
