🤖 I implement AI in VSEs/SMEs —agents, automations, custom apps, training
📱 AI agent systems in production · 2 apps designed and published on the App Store
🎓 AI Trainer (50+ professionals and executives trained)
My role: identify and frame your needs, build them, and make you self-sufficient.
⚙️ Custom Automation
Several VSEs/SMEs supported, averaging 8 hours/week saved. Examples:
- Automatic quotes and invoices
- Lead qualification and enrichment

- Meetings transcribed, summarized, actions assigned
- Weekly competitive intelligence
I build custom solutions, based on YOUR processes, with your validation on sensitive aspects.
🤖 AI Agents & Multi-Agent Orchestration
My core expertise, from design to deployment:
- Multi-agent orchestration: specialized agents that plan, execute, and monitor each other
- Harness, loop, context & prompt engineering, RAG, MCP: framed agents, connected to your documents, your tools, and your business rules
- Safeguards & security: human validation, access and cost control
- Expertise in Claude (Anthropic) and Gemini (Google): custom MCP servers, multi-model orchestration based on cost/latency/quality
📱 Custom Applications
When the tool doesn't exist, I build it from scratch:
- Product & UX/UI framing
- Full-stack development: web or mobile, backend, database
- Integrated AI (OCR, LLM, intelligent search, ...)
- Deployment
🎓 Training
I train your teams on YOUR use cases: Claude, ChatGPT, Dust · prompt engineering · creating agents connected to your data. Hands-on format.
🤝 How I work
- Written brief before building
- Short iterations, tested on your real data
- Your validation rules integrated into the system
- Delivery and final autonomy: documentation, handover, training
