Experience
Systems Engineer — Slingshot Interconnect (SDE-I) - Hewlett Packard Enterprise (HPE) - Bengaluru, India
(2025-02)
- Led end-to-end schema and models management within the HPE Slingshot mgmt-framework; designed reusable YANG model templates and successfully deployed the management framework on simulator container switches.
- Deployed separate REST management server packages for switch and control nodes, decoupling deployment units and improving modularity of the fabric configuration stack.
- Designed and deployed CRUD applications to interface seamlessly with the REST management servers, streamlining switch node configuration, telemetry monitoring, and state management for fabric administrators.
- Drove full Debian 13 (Trixie) migration of critical packages including (mgmt-common, libyang, yang-models); engineering workarounds for complex upstream dependency gaps to ensure cross-repository compatibility.
- Optimized CI/CD pipeline reliability by integrating comprehensive code coverage instrumentation across the management framework and eradicating flaky unit tests that previously blocked critical builds.
- Resolved multiple system critical bugs including fabric_bringup failures, UI access regressions along with multiple Debian package build failures and package split conflicts.
