About Valentin

Do you want to deploy generative AI in production, not just test a POC that will end up in the closet?

I design and deliver agentic systems (autonomous agents, RAG, AI automations) that actually run in production, on GCP. 3 years of experience, 3x Google Cloud certified, I handle the entire cycle: business needs framing, architecture, development, production deployment, and monitoring.

What sets me apart:
Many GenAI providers can create impressive demos. Few can make them production-ready, with security, monitoring, and scalable architecture. My dual data engineering + GenAI expertise fills this gap: I come from the world of production data (critical pipelines, zero downtime), so I don't design off-the-shelf agents; I integrate them into your existing technical and business environment.

Types of projects I can help you with:
- Automation of time-consuming business processes via autonomous agents (marketing, ad ops, customer service…)
- Orchestrated multi-agent systems (A2A, MCP) with content generation (text, image, video) and human validation
- Secure enterprise RAG (data anonymization, protection against adversarial prompts)
- Automated scoring and classification from unstructured data (text, image)
- Migration or redesign of data pipelines to prepare for AI use cases

Recent deliverables:
- 100% automated marketing pipeline (trend detection → content generation → publication), for a retail player
- Ad Ops automation agent eliminating a repetitive manual task
4 AI systems in production for a retail innovation hub (product content generation, quality scoring, visual search, secure customer service assistant)

Stack: Python, GCP (Vertex AI, Cloud Run, BigQuery), Gemini, Google ADK, A2A, MCP, RAG, Terraform.
