About Valentin

I build AI systems that pass the field test: framing with business teams, data architecture, API integrations, backend, supervised agents, and the first usable version in production.

I act as a Forward Deployed Engineer: I get in touch with the existing process, tools, and constraints, then I transform an operational irritant into a reliable internal product. The areas where I bring the most value combine business rules, rights, statuses, human validations, documents, CRM, finance, back-office, and LLM orchestration.

What I deliver: an end-to-end MVP or workflow that integrates with existing systems, documented, maintainable, with checkpoints and error recovery. Depending on the need: backend/API, structured business database, existing connectors, AI extraction, supervised business agent, dashboard, or data synchronization.

Close examples:
- Pennylane financial reporting -> Airtable and business monitoring;
- Monthly EBITDA from accounting exports and business rules;
- Pipedrive -> Airtable with deals, products, statuses, and commercial data;
- RC Pro workflow: client upload, AI extraction, human review, follow-ups, Asana, SendGrid;
- Airtable management bases with purchase orders, outstanding amounts, statuses, and decision views;
- MCP/API framework to expose business systems to AI agents.

Adapted missions: Forward Deployed Engineer, FDE, Forward Deployment Engineer, AI agents, API Integration, Backend Development, LLM Orchestration, GenAI, finance ops, CRM and back-office.

Everything went very well! Valentin communicated regularly on his progress. He quickly identified potential blind spots and was proactive in proposing solutions. He has a perfect understanding of the tools and quickly masters new ones. He accurately estimates the time his missions will take and respects deadlines. I highly recommend him and would be delighted to work with Valentin again on a future mission.
