What I can do for you

My focus: web portals that speed up your business processes – and AI tools that take real work off your team’s hands.

System integration

Connecting external systems via APIs and developing custom interfaces for desktop and mobile devices.

Mobile app development

Mobile applications for internal processes and remote access to business data.

Documentation & training

Clear, easy-to-follow user documentation and professional training for your staff.

Maintenance contracts

Long-term support for your systems through tailored maintenance contracts – for maximum operational reliability.

Tech, translated

A broad technical foundation – and what it actually means for your business.

Your path to the portal

Five stages from your current process to a running system – transparent, predictable and without surprises.

01

Process check & analysis

I take a close look at your workflow via Microsoft Teams: who does what, where does it get stuck, what eats up time? Before a single line of code is written, I work out solutions and alternatives.

✓ Free & non-binding
02

Concept & clickable prototype

Whether a short briefing or a detailed concept – the effort matches what your project really needs. You see a clickable draft early on and know exactly what you will get.

✓ Clear costs – fixed price or hourly
03

Development in stages

I develop in short stages. You have test access from day one, see every bit of progress and give feedback directly – no hidden costs, no nasty surprises.

✓ Test access from the first stage
04

Rollout & training

I bring the portal into your daily work: data migration, training for your staff and clear documentation – so your team uses the system confidently from day one.

✓ Training & documentation included
05

Support & further development

After launch, I remain your point of contact: maintenance, updates and new features as your process grows – with a fixed maintenance contract if you like.

✓ One point of contact – even after go-live

Step 1 is free.
