About Juan Manuel

Do you inspect parts by hand and miss defects? Is your production line slowing down due to quality control? I can help you automate that inspection with computer vision and artificial intelligence.

I am a robotics engineer specializing in computer vision, applied AI, and industrial automation. I help you detect defects, verify assemblies, and count and measure parts automatically, without slowing down production and reducing human errors from manual checks.
What sets me apart is that I work at the intersection of three fields that rarely go together: computer vision, AI, and automation with PLCs and robots. This means I don't just train a model and hand it over to you: I can take the project from start to finish —camera, decision logic, communication with the PLC, and robot actuation— and integrate it into your real-world production line.
Types of projects and deliverables I manage:

  • Automated quality inspection systems:defect detection, presence/absence, counting, and in-line measurement.
  • Vision for robot guidance:camera-guided pick-and-place, positioning, and sorting.
  • Integration of AI into production processes, from prototype to commissioning.
  • Automation and PLC – robot – vision communication.

I work with Python, OpenCV, detection and classification models, PLCs, and industrial robot programming, and I handle CAD for designing tooling and test parts when the project requires it.

My working method:I first understand your problem and the return you expect, propose a limited proof of concept to validate the real-world reliability, and if the results are satisfactory, I take it to production with measurable deliverables.

Remote projects. Available for occasional on-site interventions in the Alicante, Valencia, and Cuenca areas (though negotiable depending on the project and needs).
