I build systems that take manual work off your team's plate: AI assistants on your documents, process automation and stable infrastructure under your control — without depending on ever-growing subscriptions.

Free intro callPractitioner, not a salesman: everything I offer, I run in production every day — at an e-commerce company and in my own infrastructure.
Three areas, one goal: less manual work and full control over your own data.
Company knowledge is scattered across emails, PDFs and people's heads. New hires keep asking, experienced staff keep searching.
An AI assistant that answers questions based on your documents — always citing its sources. It runs on your company server or in a private cloud: your data never ends up in public models, GDPR-compliant.
The demo below runs on exactly this technology (RAG) — ask it about my projects.
Data retyped between systems, reports glued together by hand every week, quotes written from scratch for every inquiry.
Workflows (n8n) that connect your systems: shop, warehouse, email, invoicing. The first automation usually saves several hours a week — and you see it immediately.
I have run n8n in production for years: at a German e-commerce company and in my own infrastructure (a dozen-plus workflows, hundreds of executions weekly).
SaaS subscriptions grow every year while your company data sits on someone else's servers — on terms set by someone else.
A company server built on Docker: proven open-source tools instead of subscriptions, plus monitoring, backups and security. With ongoing care: updates, supervision and small changes — from €149/month.
My own infrastructure — 45+ containers with monitoring and local AI models — is publicly documented on tetes.pl.
Specialty: e-commerce. I maintain online-shop infrastructure daily (Shopware 6, integrations, order automation) — I know these processes from the inside.
A live demo is being built here: an AI assistant answering questions about my projects and articles — using the same RAG technology I implement for clients.
The same assistant can answer questions about your company's documents.
We start with a 30–45 minute consultation about your processes, not about technology (calls in German or Polish; in English we work smoothly in writing). You leave with 2–3 concrete ideas — whether or not we end up working together.
Clear scope, timeline and one price. No open-ended hourly meter and no surprises on the invoice.
Remote or on-site — travel within the Ingolstadt/Regensburg region is included. Projects in Poland: by arrangement.
Subscription from €149/month: updates, monitoring, backups, small changes. Or I hand the system over with full documentation — no lock-in to me.
Small businesses in Germany can access digitalisation grants (federal and state programmes); in Poland, FENG funds. In our call I'll tell you whether your project stands a chance of qualifying.
My name is Mariusz Binczyk. I am an IT systems administrator at a German e-commerce company, where I am solely responsible for the entire infrastructure: two online shops (Shopware 6), servers, n8n automations and AI features supporting customer service.
I have been self-employed in Germany since 2017 — starting with hosting and technical care of shops (WordPress, PrestaShop), today focused on automation and AI. Privately I run a homelab: an infrastructure of 45+ containers with monitoring and local AI models, fully documented in public.
I work in German and Polish; documentation and written communication also in English.
Tell me what your company does and what eats up most of your time — I'll reply with concrete ideas for what can be automated.
