Full-stack development
Component-based frontends with React or Angular, secure backends with well-documented REST APIs and fast database queries.
- TypeScript
- React
- Java
- Python
- C# / .NET

I build full-stack apps and connect them with cloud infrastructure and AI into solutions that work in everyday business – from architecture to deployment, well documented and maintainable.

About me
I hold a B.Sc. in business informatics (Bochum University of Applied Sciences) and work full-time as a senior software engineer. Since 2022 I have also been supporting companies as a freelancer – from automotive and pharma corporations to the public sector and SMBs.
My focus is where classic enterprise IT meets modern technology: cleanly integrating existing systems, building microservices and cloud platforms, versioning infrastructure as code and integrating AI so that it measurably takes work off your plate – privacy-compliant and traceable.
With compliu I am also building my own SaaS platform – product and operations experience that flows directly into your projects.
Services
Whether a single feature, a complete application or a new platform: I take ownership of the result – technically sound and with clear communication.
Component-based frontends with React or Angular, secure backends with well-documented REST APIs and fast database queries.
Bringing language models into existing processes: RAG over company knowledge, agents with tool access, automation – including locally hosted models.
Shipping applications to Azure, AWS or GCP – containerised with Docker and Kubernetes, infrastructure reproducible with Terraform, delivered through CI/CD.
The right architecture for your IT landscape – monolithic or distributed. Experience with API gateways, message brokers, service discovery and the ELK stack.
Connecting modern applications to SAP via OData and REST interfaces – plus support with ABAP development, CDS views and enhancements, including in IS-U environments.
Mobile apps with Flutter or React Native, fast websites and CMS solutions – including hosting, SEO and adaptation to your corporate identity.
End to end
Many projects fail at the boundaries between systems. I know every station of this chain – and build the connections in between.
Cloud, DevOps & infrastructure as code
From the first container to a highly available platform: I build environments that are reproducible, documented and delivered automatically – on Azure, AWS or GCP.
Networks, clusters, databases and permissions as code – with modules, remote state and reviews instead of clicking through portals.
Docker images, Helm charts and Kubernetes deployments – scalable, self-healing and properly monitored.
Automated builds, tests and deployments with GitHub Actions, GitLab CI or Azure DevOps – stable and shipped in minutes.
Azure and AWS certified: choosing, integrating and running the right cloud services cost-efficiently – including AI and data services.
AI in practice
No chatbot for the sake of it: I integrate language models where they save real work – with cited sources, human approval and data protection in mind.
Connecting Claude, OpenAI, Azure OpenAI or local models (LocalAI, Ollama) to existing applications and APIs.
Unlocking company knowledge through vector search – answers backed by sources instead of hallucinations.
Agents with tool calls and the Model Context Protocol (MCP) that triage tickets, validate data or support code reviews.
On-premise operation, pseudonymisation and approval workflows – so AI stays usable in regulated environments.
