Summary

Rockstar🎓
Top SchoolSankar P is a seasoned software engineer with 26 years of experience building infrastructure, distributed systems, and kernel-level components, currently at PayPal in Bengaluru. His background spans startups and large enterprises including VMware, Broadcom and Novell, with deep expertise in filesystems, microservices, service mesh, and platform engineering. He is an experienced open-source maintainer—authoring a filesystem tutorial and the popular simplefs kernel-space filesystem used for teaching (500+ stars)—and has led cross-project efforts like openSUSE GNOME and Evolution Mailer. Sankar combines low-level systems craftsmanship with cloud-native platform work, making him equally comfortable in kernel code and modern distributed architectures. Colleagues rely on him for pragmatic designs that bridge theory and production, and a lesser-known strength is his long history of mentoring through tutorials and community leadership.
