Edwin Castellanos

Edwin gravitates toward line-of-business desktop software in C# — management systems for a dental clinic, a restaurant, and an aesthetics studio, plus an HTML/CSS layout exercise. The breadth across backend, frontend, and a bit of game-dev shows curiosity, but every project carries zero stars, the account has gone quiet (no commits last year), and there are no external OSS contributions. This is a junior, project-by-project track record — competent practice work that hasn't yet been validated by users or collaborators.
