Scouting report

Math-trained data scientist with early computer-vision experiments

assessed from open-source footprint

Junior
42signal

Alejandro comes from a mathematics background (applied-math master's coursework appears in the repos) and is moving into data science and computer vision. The work includes a neural-network optimization case study, a 100-topic computer-vision learning challenge, and an R utilities collection — coherent for someone building ML foundations. Signal remains thin: five repos, no stars, only two commits last year, and most projects abandoned. The mathematical grounding is a real differentiator, but there's no deployed or external-contribution evidence yet to corroborate practical delivery.
