Description

I build AI-powered products — from architecture to go-live.

As a Senior Full-Stack AI Engineer, I bring together two things rarely found in one person: deep experience in building scalable cloud applications and a proven methodology for AI-native development with agentic workflows.

What this means in practice

I orchestrate AI agents (Claude Code, OpenAI) to implement complex software projects — delivering results that would typically require an entire team. A current example: a production-ready GenAI platform with mobile apps and an automated data pipeline — implemented in 5 weeks instead of the usual 6+ months.

My project focus areas

GenAI integration & LLM pipelines (RAG, Conversational AI, data processing)
Full-stack product development (Web & Mobile, React, React Native, TypeScript)
Cloud architecture & migration (GCP, Firebase, Cloudflare, Terraform)
AI-powered process automation for internal teams

What sets me apart

Before my engineering career, I was a VP at Deutsche Bank and managed operations with 70+ employees as a hotel director. This means: I understand not only the code but also the business problems behind it — and can discuss both with decision-makers at eye level.

Numbers from my work:

80%+ reduction in investigation time through AI agent with custom MCP servers
Platform modernization across 1,293 files — fully implemented via Claude Code (~92K lines net removed)
200+ Cloud Functions migrated, zero downtime
63% higher PR throughput through AI-powered code reviews

I prefer to work with companies that understand AI not as a buzzword, but as a tool for real results.
