Über mich

Senior Full-Stack Developer (since 2006) building AI-powered products end to end — from the first idea to production. UC Berkeley CTO Program graduate (Certificate of Excellence in Technology Strategy).

What I build:
- Agentic AI systems — workflows in which AI agents plan and carry out multi-step tasks
- AI advisory & recommendation engines — e.g. a career navigator that guides candidates to best-fit jobs
- LLM document & data processing — extraction, transformation, converters generated from a plain-language description
- Full-stack SaaS platforms — multi-tenant apps, admin dashboards, design systems, payment integration (Stripe, Paddle)

Tech Stack:
- Frontend: React 19, Next.js, TypeScript, Astro
- State & UI: Zustand, TanStack Query, Redux Toolkit, Radix UI, shadcn/ui, Tailwind CSS, Storybook
- Backend: Node.js, Express, Go, Java / Spring Boot
- Databases: MySQL, MariaDB, MongoDB, Oracle, libSQL, Payload CMS
- AI/LLM: AI agents, RAG, embeddings, MCP servers, semantic search, prompt engineering, LLM cost optimization; OpenAI, Gemini, Mistral, Ollama
- AI-assisted development: Claude Code, GitHub Copilot, coding-agent workflows, AI code review
- DevOps: AWS, Terraform, Docker, GitHub Actions, Jenkins, RabbitMQ
- Testing & quality: Vitest, Jest, Playwright, Testing Library, WCAG 2.2 AA

Track Record:
- File conversion SaaS, founded and run since 2010: 150+ converters, files up to 100 GB, 40k+ monthly visitors
- Multi-tenant quality-management platform for medical institutions (Java / Spring Boot backend, React frontend)
- Co-founded a wedding marketplace with AI-powered tools as CTO — cited by Cosmopolitan
- Car configurators for VW, BMW, Porsche and Lamborghini at Dassault Systèmes 3DEXCITE; designed the architecture of a digital asset platform that won a 3-year, €3M Toyota Motor Europe contract
- 9 years in regulated financial services (State Street): build and release automation, enterprise integrations

How I work: strong technical intuition and a knack for unusual solutions. I turn ideas into a working proof of concept fast, and I know when to trade speed for depth. Independent, low-ego, 18+ years of remote collaboration with international teams.

Availability: remote; part-time now, full-time by arrangement.

Weitere Kenntnisse

Additional programming languages: Go, Java, Python, PHP, Rust, C/C++, Perl

Methods: Agile (Scrum / Kanban), code reviews, pair programming, technical mentoring
