assessed from open-source footprint

Senior
53signal

Jarolin is a solo author (22 commits last year, 6 PRs merged) building backend skills in Java and the SAP/ABAP stack. The flagship repo is a Java Spring Boot project framed as professional REST-API architecture, alongside ABAP CDS practice work. With only 7 repos and minimal stars, this is a focused, learning-driven backend portfolio rather than a proven body of shipped systems.
