About Arielle Diana

Senior Full-Stack Engineer & AI Consultant with 20+ years shipping code — from founding startups and scaling teams as CTO, to delivering enterprise-grade applications for Roche, Siemens, and AutoScout24.

Deep roots in ML/NLP since 2013 (Siemens, Cliqz, Building Radar). Now building AI-powered products, agentic workflows, and automation systems.

Hands-on engineer who architects, codes, and ships — not a manager who lost touch with the codebase.

Current tech-stack:
Frontend: React, TypeScript, Next.js
Backend: Node.js, Python
AI: Claude, OpenAI, RAG, Agentic Workflows, n8n, MCP
Cloud: AWS, Google Cloud, Serverless

Available for senior contract roles, AI integration consulting, and fractional CTO engagements.
