Your systems don’t talk to each other?
I fix that.
I build software and interfaces that keep your digital processes running reliably – from backend and APIs to integrations and data workflows. Pragmatic, security-conscious, and maintainable.
For mid-sized companies and as reinforcement for existing teams – from technical scoping to reliable day-to-day operation.
20+ years of experience • Web, mobile & desktop • Backend, APIs & integrations
Typical problems I solve
Systems and data that don’t fit together
CRM, ERP, shop, PIM, ticketing system: data is everywhere, but it doesn’t fit together cleanly. That leads to manual exports and imports, duplicate work, and errors at handoffs. Validation, transformation, and reliable API access for external partners are often missing.
Missing or unsuitable software
Standard software doesn’t fit, and existing solutions are missing or only cover part of the requirements. As a result, simple tasks turn into manual workarounds, and everyday processes become harder than they should be.
When someone in your company says, “This should really be simple …”, it often should be. I help get complexity under control so it works simply for you.
How I help
Backend & APIs
I build stable backend services and APIs for your applications or external partners. REST, GraphQL, and event streaming – secure, performant, and clearly documented.
Access control and permissions, error handling, and reliable operation are built in from the start.
Integrations & Workflows
I connect your systems (CRM, ERP, shop), automate data exchange, and make imports reliable. Connect APIs, build interfaces, stabilize processes.
I use AI where it measurably helps – for example in extraction, classification, translation, or search.
Custom software
Web, desktop, or mobile applications: I build software that fits your requirements.
From the initial idea to the finished application – pragmatic, maintainable, and built to support long-term use.
What you get
- Stable backend systems and APIs for your applications
- Integrations that exchange data reliably
- Software that fits how you work – instead of new compromises
- More security and transparency through clean structures
Why work with me?
- Over 20 years of experience across different industries and system landscapes
- I know both sides: technical implementation and business requirements
- Direct collaboration without detours – you always work with me
- Pragmatic execution focused on stable, maintainable solutions instead of buzzword bingo
Also for larger teams:
Senior Engineer reinforcement
If you already have a team, I support your projects as a Senior Engineer – hands-on in implementation, with a clear eye for technical decisions and clean structures.
I have many years of experience in agile teams and support flexibly with integrations, extensions, migrations, and modernization work. I move forward the topics that often get stuck in day-to-day work.
Remote – and happy to be on-site for kickoff or workshops.
You work directly with me. No agency, no middleman.
