- Senior engineer and organizational code owner on a globally distributed team building the management software stack for DDN EXAScaler: installation, configuration, and monitoring of the Lustre filesystem at scale.
- Responsible for technical stewardship across multiple repositories: code review and patch gatekeeping, CI workflow ownership, API and RFC review, and the design, implementation, and testing of production features.
- Authored a pure Rust async-I/O orchestration engine running thousands of tasks in parallel over SSH, for higher performance, resiliency, and operational visibility during large-scale cluster operations.
- Core contributor to Google Cloud Managed Lustre, jointly developed with Google to bring Lustre to Google Cloud as a managed service; recipient of the DDN Velocity Award for the contribution.
- Operating at Senior Staff scope since December 2025: trusted technical voice in critical customer escalations and a consistent cross-program RFE and design reviewer, raising the technical quality of engineering decisions.
- Architectural contributor during the NVMesh (NVIDIA software-defined storage) design phase; helped shape strategic storage initiatives by bridging deep technical detail with program-level thinking.
- Mentor and technical standard-bearer in the EMF team: raising engineering practices, code quality, and design rigor as the team scales.
- Joined in 2022 as a Lustre subject-matter expert resolving LNet and performance escalations and running EXAScaler 5.x/6.x upgrades, before transitioning into engineering in 2024.
Resumé
Professional Experience
- Lead specialist for a broadcast and media-optimized storage system based on IBM Spectrum Scale®: development, incident and problem resolution for complex customer setups with multi-site replication, Amazon S3 cloud tiering, and more than 22 GB/s combined data rate.
- Set up clustered storage PoCs and production installations at international customer sites including Beijing and New York.
- Optimized networks for 100 Gbit/s Ethernet throughput.
- Migrated the product from bare-metal deployment to containerized infrastructure, simplifying field installs and accelerating release cycles.
- In a team of five, developed cross-platform driver and OEM SDK (Linux, Windows, macOS) for FPGA-based professional video PCIe boards.
- Built a hybrid software and hardware JPEG 2000 de-/encode accelerator board, used in R&S Clipster® 6.x and upwards.
- Integrated a hardware-based RSA de-/encryption solution for creating encrypted DCI packages for Digital Cinema (R&S Clipster® 6.x).
- As project manager, defined the software architecture and coordinated resources for the R&S Prios® board, used by internal product lines (R&S Venice®) and external OEM customers.
- Led a 40G SMPTE 2110 uncompressed Video-over-IP solution with up to 4K resolution on the Prios® platform; participated in JTNM Interop at The Woodlands, TX, and the implementation was later shown in the IP Showcase at NAB 2018 in Las Vegas, NV.
