From payment processing through AI image processing to the marketing workflow — every layer under one roof, without third-party tools. Stripe Subscriptions, Supabase RLS, custom CV pipeline, marketing automation.
A digital service middleware for building automation: RAG knowledge base over DIN standards, agent-based workflows, interactive standards lookup with real-time streaming. Sensitive data stays in the EU.

Cleanly built software that runs — and that you can extend three years from now without a refactoring marathon.
You have SAP, a legacy ERP, Excel workflows. I integrate AI exactly where it saves time — without reinventing your stack. Interfaces, not greenfield.
From pitch deck to live-deployed app: full-stack build with payments, auth, AI features — all from one hand. You talk to the developer, not to an agency.
Code reviews, RAG architecture sessions, pair programming on tricky migrations. Discreet, technically deep, German business hours.

Six topics that apply to everyone in 2025/2026 — cookie banners, data protection, AI Act, accessibility, e-invoicing, AI agents. I explain what is mandatory, and I implement it.

AI labelling, risk classification, human-in-the-loop. Prohibited practices since 02.02.2025, high-risk from 02.08.2026.
Mandatory for B2C websites, apps, e-commerce. WCAG 2.2 AA, keyboard operation, screen readers, statement page.
Structured XML (XRechnung or ZUGFeRD), 8 years archive. PDF alone no longer enough.
Audit trail per run, approval gates, EU-hosted models, rollback paths. AI Act and GDPR Art. 22 thought together.
