Services
I deliver web apps.
Rotating terms: web apps, integrations, automation, AI integration, your own agent team
From the first sketch to years of operation: software, integrations, automation and AI — delivered by me and my agent team, reviewed and traceable.
01 — Custom software & web apps
Software for real-world operation.
Off-the-shelf software rarely fits exactly. I build applications that adapt to your workflows — tested and reviewed before they go live.
Web apps & portals
Customer portals, internal tools, booking and management systems — responsive, fast and intuitive.
Platforms & marketplaces
Applications with many locations, roles and users — from appointment booking to a marketplace with search and payments.
Web shops & point of sale
Online sales that work together with the store on site — including import of existing product data.
Mobile apps & PWAs
Apps for iOS and Android or as a progressive web app — including for use out in the field, such as on-site handovers.
02 — Interfaces & integration
Your systems, connected.
Software rarely stands alone. I make sure your applications talk to the systems you already have.
APIs & formats
REST/JSON, SOAP, XML or CSV — data flows between your systems instead of being retyped.
Accounting & payroll
Integrations with DATEV, Sage and similar systems, so billing and accounting work without detours.
Payments & portals
Payment processing and connections to external portals — wherever your process reaches beyond your own application.
When there's no API
If a system only offers a CSV download, I build an interface around it — until a real one exists.
03 — Process automation
The work that comes in every day — done.
Many workflows follow the same pattern every time and still tie up people. I automate that work, you stay in control.
Requests & inbox
Read incoming requests, sort them and pass them to the right place — with a draft reply where it makes sense.
Analyse documents
Contracts, receipts, forms: the relevant details are extracted and filed where they're needed.
Handovers & reports
Prepare minutes, status reports and handovers, so nobody has to piece them together on a Friday evening.
Human sign-off
Anything that goes out or has consequences is signed off by a human. Every step is logged and traceable.
04 — AI consulting & AI integration
AI that saves work
Rotating terms: saves work, knows your data, follows your rules, measurably helps
Language models are powerful — but only useful when they are properly wired into your workflows. That's exactly what I do.
Finding use cases
I look at your processes and show where AI really saves time — and where classic software is the better choice.
Integration via API
Current language models wired straight into your existing systems — instead of adding yet another silo.
Prompt & context design
Good results need good instructions and the right context: your documents, your terminology, your rules.
AI in the product
Copy from a few bullet points, content in two languages, speech to text: AI features right inside your application.
Privacy & quality
I keep track of which data flows where and test results systematically — so the demo becomes a reliable tool.
05 — Prototypes, MVPs & mockups
Your idea, tangible fast.
Sometimes it just has to be quick: to test an idea, convince investors or win support internally.
Mockups
Clickable drafts that show how the product feels — before a single line of production code is written.
Prototypes
Live online and testable with real people — so you find out early what holds up.
MVPs
The first real version, lean in scope and solidly built. More than once, one of my MVPs has become a product that ran for years.
And then?
I keep building, hand over cleanly to your team or stay on board as a partner — your call.
06 — Operation, maintenance & development
So your software still runs three years from now.
Software is never finished. I stay on board — as long and as much as you need.
Hosting & monitoring
Operation on servers in Germany or in your own infrastructure, with monitoring and backups.
Maintenance & updates
Security updates, dependencies, small bugs — dealt with before they become a problem.
Further development
New features, new locations, new requirements: your software grows with your business, for years if need be.
Modernisation
Renew legacy applications step by step without putting day-to-day operations at risk.
07 — Agent teams
Set up. Run. Hand over.
One offering among several: a team of AI agents with fixed roles, mutual review and clear sign-offs — tailored to your project.
Set-up
I put together the roles your project needs and set up rules, reviews and sign-offs.
Operation
I lead the team for you: slicing tasks, reviewing results, making progress visible.
Handover
Want to carry on yourself? I hand over the team together with its rulebook — just like with KeyHub.
3 today, 42 tomorrow
The team grows with your needs and gets smaller again when things calm down.
08 — Outlook · Digital twin
Knowledge that doesn't go on holiday.
Where this is heading: employees get a digital copy with their knowledge, and, if they want, with their voice. This is an outlook, not a finished product.
Onboarding
New colleagues ask the twin instead of waiting for a free slot in someone's calendar.
Cover
Holiday or sick leave: the twin prepares, the original decides on their return.
Consent only
No copy without consent, no voice without an explicit yes. The twin always identifies itself as AI.
09 — Working together
3 today, 42 tomorrow — as much as you need.
Not every company needs its own development department. Bring in capacity when you need it: for a clearly scoped project or on an ongoing basis.
Project
Fixed scope, clear goal — from mockup to finished software.
Ongoing support
Operation, maintenance and further development, flexible to your needs — with your own agent team if you like.
Sparring
A second opinion on architecture, technology choices or AI strategy.
