Need an AI agent or full-stack product shipped without the overhead of a team? I'm a Senior Full-Stack Engineer and AI Agent Developer with 10+ years — $330K+ earned on Upwork, Top Rated Plus, 100+ projects delivered.

I work as a single senior owner across the full stack: architecture, AI integration, and delivery. No handoffs between a PM, a designer, and a junior dev. I use AI tooling (OpenAI, Claude, LangChain) to accelerate development while keeping the codebase clean, testable, and maintainable after launch. I'm also fluent in English and German, which makes me a natural fit for European and DACH-market clients

✅ AI Agents & Automation
Custom agent workflows, OpenAI/Claude integrations, CRM automation pipelines (n8n, Make, Zapier) — built to reduce manual workload, not just demo well.

✅ Full-Stack Product Development
Next.js, React, Node.js, TypeScript, Strapi, PostgreSQL. Scalable, cloud-ready architectures from spec to production.

✅ SaaS MVPs & Internal Tools
Idea → architecture → ship, with the discipline to keep the codebase maintainable post-launch.

✅ Fractional CTO
Technical roadmaps, hiring support, and system reviews for non-technical founders who need a trusted technical partner.

Recent outcomes:
• AI lead-generation + CRM automation pipeline → cut a client's outreach workload by ~70%.
• Strapi-based fullstack app delivered from spec to production in under 3 weeks.
• Enterprise WordPress estate maintained across 2,800+ billed hours for a German-speaking client — 5.0 rating.
• 100% JSS, Top Rated Plus badge, 4.98 average rating across 53 contracts.

If you're building an MVP, integrating AI into an existing product, or need a technical partner who can own the full stack — send me a message. I typically respond within 4 hours.
