Rockstar🎓
Top SchoolMarc Bernard is a founder and software entrepreneur who builds open-source tools for SAP customers, partners, and developers while leading apm.to Inc. and Marc Bernard Tools. With a multi-decade background at SAP in architect and consulting roles, he brings deep domain expertise in BW/ABAP and practical experience shipping both back-end and front-end improvements in notable projects like abapGit and the Verdaccio registry. As a solopreneur and digital nomad, he combines hands-on engineering—fixing semver internals and UI quirks—with product intuition to create developer-facing tooling. His work often surfaces non-obvious value, such as improving debug metadata for SAP clients and refining package UX for private registries, reflecting a mix of technical rigor and user empathy.
