Scouting report

Early-career Dominican dev practicing Python recommendation systems and sentiment APIs

assessed from open-source footprint

Mid
49signal

Junior Santo Domingo Este developer (1.9-year account) focused on Python/Jupyter data work. Output is small but disciplined: a perfect 0 abandoned ratio, 88 commits last year, and a meaningful 12-commit contribution to an external SentimentAPI repo. Named projects ('Recommendation_system_practice', a personal portfolio) are clearly learning-oriented with no stars yet. An early-stage but consistent and genuinely active profile rather than a proven one.
