Alex UrbinaComputer vision consultant for 3D scans, images and drawings.

Need AI that reads images, PDFs, drawings or 3D scans and works on real data, not just in a demo? I build computer vision and AI agent systems that reach production.

From scan to model

Scroll, and a laser scan becomes a building model

My scan-to-BIM pipeline turns laser scans into floor plans and IFC models. Scroll through a real job; every number below comes from it.

Six million points

A laser scan is a cloud of coloured points. It has no walls, no rooms and no dimensions you can build from.

Find level

The scan is levelled automatically, so every measurement starts from a truly flat floor.

Slice at wall height

Seen from above at wall height, the floor plan starts to appear from the points themselves.

An AI agent traces the walls

An AI agent draws the walls on top of the scan, and its work is checked against the scan before anything moves on.

Measure doors and windows

Doors and windows are found in the scan and sized from it.

Extrude to a model

Walls rise to their own measured height. The result exports as an IFC building model and a DXF floor plan.

How I help as a computer vision consultant

From the first conversation to a system your team runs: computer vision, machine learning and AI agents, built for production. My specialty is the built world: scans, drawings and BIM.

Feasibility before building

Before a long build, we check together whether the idea holds up on real images, scans or documents, and what it would cost to run.

Computer vision and machine learning pipelines

Detection, segmentation and 3D reconstruction, from photos and video to point clouds, with vision-language models where they earn their place.

AI agents that check their own work

Agents that verify their output against your data instead of trusting the first answer.

Production, not a notebook

GPU workers, APIs, web viewers and the product around them, built so a team can run and extend it.

About

An engineer who ships the whole thing

I trained as a civil engineer in Lima and worked in BIM before I wrote software for a living. Since then I have co-founded two grant-funded startups, spent two and a half years building point-cloud and BIM tools for a US company, and finished an M.Sc. in Data Science at Aalto University with honours.

Today I work as a computer vision consultant and AI engineer: computer vision, machine learning and AI agent systems that work on real data, such as laser scans, 360° video, photos and drawings. I like owning a problem end to end, from the research question to the GPU worker, the web viewer and the invoice.

  • I validate on real data first and report honestly what works and what fails.
  • I design for cost per run and failure cases, not only demo accuracy.
  • I'm looking for long-term work with a team that ships.

Questions

Working with a computer vision consultant

What does a computer vision consultant do?

I help a team decide whether a vision problem can be solved with their data, then design and build the system: data, models, evaluation and the software that runs it in production.

What kind of data do you work with?

Laser scans and point clouds (E57, PLY, LAS), 360° and regular video, photos, PDFs and technical drawings, and BIM models (IFC, Revit).

How does a project start?

With a video call to get to know each other: the problem, the data you work with and your team. If it is a good fit, I propose a plan before any long engagement.

Do you work long-term?

Yes. I prefer long-term work with one team, owning a part of the product end to end. My longest client engagement lasted two and a half years.

Contact

Have scans, images or drawings that need to become data?

Tell me what you are building. I read every message, reply by email, and I'm happy to set up a video call to get to know each other.
