Why should you work with me ?

BACKGROUND
Bachelor in Digital Commerce Management at the Duale Hochschule Baden-Württemberg (DHBW) — Germany's dual study system that combines university with three years of structured professional practice in a partner company. Graduated 1.6 (sehr gut).

I work across the full stack: web applications, backend systems, data pipelines, AI integration, and e-commerce. Comfortable picking up the right tool for the job rather than forcing a single framework.

CURRENT WORK

(1) Configurable application portal for a state-affiliated agency (PHP 8.3, framework-free, config-driven). Multi-step forms with conditional logic, secure document upload, real-time validation, PDF generation, structured data export. Full theme infrastructure for visual variants. GDPR / DSGVO compliant by design, hosted in Germany. In production.

(2) Batch-oriented AI catalog processing platform (Catalyst Transformer): multi-provider LLM abstraction (Anthropic Claude, OpenAI GPT, Google Gemini), workflow orchestration via n8n, Postgres/Neon for state, idempotent worker pipeline on Cloud Run, deterministic recovery semantics. Built solo, in production for product data enrichment.

WHAT I CAN BUILD
- Web applications and portals (PHP, Python/Flask, modern JS)
- Backend services and REST APIs
- E-commerce extensions and integrations (Shopify, WooCommerce, custom)
- Data pipelines and batch processing (Python, Postgres, Google Cloud Storage, Cloud Run)
- AI / LLM features inside client products — intake classification, automated drafting, structured output generation, retrieval-augmented systems
- Admin backends, dashboards, internal tools
- WordPress / Drupal / TYPO3 customization and integration
- GDPR / DSGVO compliance and EU hosting

HOW I WORK
- Fixed-price preferred — no surprise hourly bills
- Typical delivery 4–8 weeks depending on scope
- Direct contact — no PM layer, no account manager, no offshore subcontracting
- Bilingual DE / EN

BASED IN
Berlin / Mecklenburg-Vorpommern, Germany.
