Business software specialist · since 2001
Specialist in
As a business software specialist, I bring clarity to systems that have grown over years, find the bugs others give up on and build new software – with more than two decades of experience and the latest AI tools.
01 — Services
I deliver every project in German and English – from analysis, code and documentation to training your team.
DEEN Projects in German and English
Legacy systems, unfamiliar code, missing documentation? I give you clarity on architecture, data flows, risks and technical debt – and develop your existing software further without putting day-to-day operations at risk.
Sporadic crashes, wrong results, systems that suddenly slow down: I find the root cause – systematically, reproducibly and with a lasting fix instead of treating symptoms.
When a fresh start is the better choice: I design and build your software from the ground up – cleanly structured, maintainable, tested and tailored to your processes.
02 — Industries
Every industry has its own processes, rules and requirements. I have already worked in these industries – and that knowledge goes into every project.
03 — Oracle
The database is the heart of your application. I know Oracle from more than two decades of hands-on work – from PL/SQL logic and data modelling to tuning queries that take minutes instead of milliseconds.
Illustrative example
04 — Artificial intelligence
I use AI agents and assistants such as Claude, Claude Code, ChatGPT, GitHub Copilot, Microsoft Copilot and Devin productively every day. The result: analysis and development in a fraction of the time – reviewed and owned by a developer who knows what matters.
AI-assisted code analysis makes sense of even large, undocumented codebases in a short time.
Agents such as Claude Code and Devin take over routine work – I focus on architecture and quality.
Every line is reviewed. AI is a tool, not a substitute for responsibility and expertise.
Whether ChatGPT, Microsoft Copilot or Claude: I help you introduce AI tools to your company in a meaningful way.
05 — AI consulting & training
I support small and mid-sized companies from the first use case to productive operation – with honest advice and hands-on training that brings your people along.
Data protection from day one: GDPR, data processing agreements and the EU AI Act
Example: From enquiry to quote
Create, summarise and search contracts, quotes, reports and emails faster – and make knowledge accessible through internal assistants.
Pre-sort enquiries, prepare standard replies, handle tickets faster – your team takes care of the complex cases.
Quotes from text blocks and CRM data – in minutes instead of hours.
Image analysis spots defects on the line, sensor data predicts maintenance needs (predictive maintenance).
Capture invoices and receipts automatically, assign them and submit them for review.
Write, test and document code – including customisations of specialist software.
Recurring tasks are taken over – qualified staff can focus on value-adding work.
Let's find out together where AI brings you the most value.
What AI can do – and what it can't. Safe, responsible use of AI tools in everyday work.
Together we identify the processes where AI delivers the most value for reasonable effort.
From concept to a measurable pilot project – including integration into your existing software.
Hands-on training in German or English, tailored to business departments, IT and development – e.g. with ChatGPT, Microsoft Copilot, Claude & co.
Which processes take a lot of time, are repetitive and have clear outcomes?
Prioritise two or three use cases with a good benefit-to-effort ratio.
Start small and measure time, error rate and cost.
Consider GDPR, data processing agreements and the EU AI Act from the start.
Involve staff early, take concerns seriously, build skills.
Move successful pilots into regular operation.
Good consulting names them – and makes sure they don't harm your business.
06 — AI-assisted web design
AI tools produce designs, copy and code in a short time. My experience as a developer turns them into a fast, accessible and privacy-friendly website.
A modern website for our craft business – with services, references and a contact form. Easy to read on a smartphone.
… then reviewed, refined and published by me.
Several design options in a short time – you choose, I refine.
Optimised for smartphone, tablet and desktop – with checked contrast and keyboard navigation.
No unnecessary cookies, no externally loaded fonts – and no cookie banner if you prefer.
Animations that explain content rather than just decorate it – just like on this page.
07 — Approach
We talk about your system, your problem and your goals – with no obligation.
I get a thorough overview and identify causes and options.
Bug fixing, optimisation or new development – in traceable steps.
Documented, tested and handed over so your team can continue working with it.
08 — Contact
Whether it's an urgent problem, a new project, AI training or a new website – write to me in German or English. I'll get back to you personally and promptly.
