AI Data Infrastructure · 5-Day Sprint

Your AI concept. Working. By Friday.

AI is only as good as its data. I connect your existing systems, build clean data pipelines, and make your AI investment actually deliver — kickoff to prototype in 1 week.

What I Build

Three focused offerings.

Scoped, deliverable, owned by you. No vague engagements, no retainer traps. Pick the right starting point.

01
5-Day Sprint

Day 1 · 4h kickoff. Day 3 · 2h review. Day 5 · 2h live demo. ~8 hours of your time. You get source code, documentation, and a deployed prototype — ready to show stakeholders or go to production.

AI Prototype 1 Week Owned
02
AI Data Infrastructure

ERP, CRM & legacy API integration. Clean, AI-ready pipelines. Structured retrieval, embeddings, and context layers — built on infrastructure you control. EU-hosted, GDPR-compliant, your data stays in Europe.

ETL Integration GDPR EU-Hosted
03
B2B Portals & Custom Systems

Booking portals, fleet dashboards, invoicing automation, BI dashboards. Built to own — not to subscribe to. Live examples across 6 production systems running at ~€5/month infrastructure cost.

Booking Dashboards Invoicing Automation
Pricing

Start with a sprint.
Scale from there.

One fixed entry point. You see results before committing to anything larger.

Retainer

Keep the momentum.
After the sprint.

I maintain, extend, and operate what we built together. Flat monthly fee, no lock-in contracts, cancel any time.

  • Ongoing maintenance & updates
  • Feature extensions on request
  • Infrastructure monitoring included
  • Cancel any time — no minimum term
Starting from €99/mo Scales with scope

Not sure where to start? We'll figure it out in the first call — 60 min, free.

Why Lukas

I build complete
systems. Not features.

01

One engineer, full stack

From data pipeline to AI layer to deployed prototype — one point of contact. No briefing ping-pong, no agency overhead.

02

5-Day Sprint · ~8h your time

Long POCs are how AI projects die. You get a running prototype in one week — then decide whether to scale it.

03

You own the technology

EU-hosted, GDPR-compliant, no vendor lock-in. The code and the data are permanently yours. Cancel any time without losing anything.

04

Data first, AI second

AI is only as good as its data. I fix the foundation before building on top of it — clean pipelines, connected sources, reliable output.

Case Study — Boat tour operator, Berlin

From spreadsheets to a complete digital ecosystem
