I build automation and custom software that handle your repetitive tasks and customer inquiries — so nothing slips through and no one waits.

A single inquiry, handled end to end — without anyone touching a keyboard.
≈ 13.0 weeks of full-time work each year
Most inefficiency is invisible. It hides inside everyday tasks that feel normal — until you add up the hours.
Messages arrive after hours and sit unanswered. By morning, the buying impulse — and sometimes the customer — is already gone.
The same information is retyped from inbox to spreadsheet to CRM. Hours disappear into work that creates nothing new.
An inquiry slips between a chat app and a notebook. No one followed up, and no one noticed the revenue that walked away.
Your tools each hold a piece of the truth, but none of them share it. People become the integration — manually, every day.
Work stalls because a single step depends on a single person. Growth makes the queue longer, not shorter.
Same inquiry. Same systems. The difference is everything that used to happen in between.

Automation isn't the goal. These are.
Inquiries are acknowledged and routed instantly, day or night — so interest never cools while you sleep.
The copy-paste tasks that drain your team's day are handled silently in the background.
Every inquiry, status and handoff is recorded — so you can see what's happening without asking around.
When data moves itself, it stops being retyped, mislabeled and lost between systems.
More volume no longer means more headcount. Your systems absorb the growth.
Hello, I'm Tim-Luka Stahl.
I'm a software developer and business automation specialist. I work directly with each client to identify inefficiencies, automate repetitive work and build systems that improve operations.
From the first strategy call to the live solution, there is no layer between us. You explain the problem to the person who designs and builds the answer.
From strategy to implementation, you work directly with me.
Bachelor's degree, University of Applied Sciences Flensburg · Trained technical writer · Software developer & AI-automation engineer · Currently building CE-compliance software for a German engineering firm.
Not mock-ups — systems I have designed and built for a university, an engineering firm, and my own product.
Standardized module handbooks across every degree program
Module handbooks were scattered across dozens of degree programs, each with its own layout, styling and terminology, maintained by hand. I built a web application where every professor edits in one shared place — so the final handbooks come out consistent in layout, terminology and structure, in German and English for international students. Faster to produce, with no manual post-editing.
Software that generates CE machine-safety documentation
An engineering office specializing in CE conformity for machine safety under European standards. I work as their developer, DevOps and AI-automation engineer, building the software that produces their compliance documentation — pairing my background as a trained technical writer with AI agents that draft, structure and check the paperwork machine certification demands.
A shipped AI product for education
My own product: a desktop application for education with a built-in document editor (Word/PDF export), homework and class management, and an AI agent that works across OpenAI, Anthropic, Gemini and local models. Live, in active testing, with regular releases — end-to-end proof of what I build: design, software, AI and shipping.
A clear path from "this is slowing us down" to "this runs itself."
We map how work actually flows today — the tools, the handoffs and the hours quietly leaking out of your operation.
Straight answers to what businesses ask before we start.
There's no fixed price tag, because the right solution depends on what we're automating. So here's how it works: we start with a free audit, and before any work begins you get a clear, fixed quote — no surprises, no obligation. Most automations pay for themselves in recovered time within months, and we start with the one that returns the most, fastest.
One line is enough. I read every message myself and reply within 24 hours — no obligation.
Or reach me directly
In a short conversation I will identify practical opportunities to automate processes and improve efficiency — with no obligation to continue.
