Alejandro Duque Velázquez

Worth flagging plainly: Alejandro's one public repo is a fork of libvpx (Google's WebM/VP8-VP9 codec library), and the authorship signal reads 'Not primary author' — so the C codebase and its relative polish reflect the upstream project, not his own work. The 11-year-old account shows one follower, no stars, no commits last year, and no verified external contributions. A systems/C interest is evident from what he chose to fork, but there's no original output here to evaluate. Honest take: the visible material doesn't yet demonstrate authored work; direct portfolio review would be needed.
