About Sergio

I build computer vision and AI systems that work in the real world — not just in notebooks.

AI & Computer Vision Engineer based in Luxembourg with an MSc in Computer Vision & AI (University of Luxembourg) and 2.5 years of industrial experience deploying real-time visual inspection systems on live production lines. When a defect-detection model has to survive vibration, changing light and 24/7 line speed, "it works on my laptop" isn't good enough — that's the standard I bring to every project.

What I deliver:
• Custom object detection & segmentation models (YOLO11, SAM 2) trained on your data
• Industrial visual inspection: camera/optics/lighting selection + algorithm + deployment
• AI chatbots (Claude/GPT) grounded in your business knowledge base
• LLM workflow automation (n8n, Make, Zapier) with deterministic checks around the LLM
• Dataset annotation pipelines and ML evaluation

Proof of work (open source, live demos):
• Reproducible detection/segmentation benchmark (YOLO11, RF-DETR, SAM 2, Mask2Former) — Zenodo DOI
• Building-intelligence RAG copilot over public data from 3 countries
