Scouting report

Cuba systems engineer — graph-theory and C++ framework author

assessed from open-source footprint

Staff
52signal

Javier's standout is jlibgraph (10★), a comprehensive Java graph-theory and algorithms library, alongside libartemis (4★), a C++98 framework mirroring the Java Class Library. With 84 PRs merged and a clear systems/algorithms specialty, the depth is real for a CUJAE undergrad. Caveats: low consistency and 100% abandonment with no commits last year — a strong systems-engineering candidate who needs an activity check.
