I am a Software Engineer at Crusoe, where I am designing, building and maintaining high-performance networking infrastructure for Crusoe Cloud. Previously, I was a researcher at MIT PDOS (Parallel & Distributed Operating Systems), advised by Adam Belay. My professional interests include cloud computing, networking, operating systems and systems for AI.

## Work Experience
### Software Engineer @ Crusoe
Jan 2024 – Present | San Francisco, CA
• Co-designed, built, and maintain high performance networking infrastructure for petabyte-scale Managed NFS; achieved up to 8x throughput improvement and 30% latency reduction; delivered 3 weeks ahead of schedule, directly enabling 8-figure strategic partnerships
• Co-designed and own foundational SR-IOV-enabled VM-to-service networking architecture, used across Crusoe Cloud products like Managed NFS, VPC Interconnect, Object Store, and Crusoe Container Registry 
• Built high-performance networking infrastructure for S3 Storage SDK, enabling the launch of Decart’s real-time video-to-video model on Crusoe Managed Inference
• Led production operations, including zero-downtime migrations, customer escalations, incident response, and capacity rollouts for customer-facing infrastructure
• Established foundational team processes and onboarded 5+ Senior and Staff+ engineers onto the SDN architecture and operations

### Undergraduate Researcher @ MIT Computer Science and Artificial Intelligence Laboratory (CSAIL)
Jan 2023 – Jan 2024
• "Rethinking Process Snapshots for Near-Warm Serverless Cold Starts." B. Holmes, B. Dinis, L. Honcharuk, J. Fried, A. Belay. 20th USENIX Symposium on Operating Systems Design and Implementation (OSDI '26) (to appear)
• Built a low-level page fault tracer to characterize memory use of serverless runtimes after snapshot restore for serverless cold start optimization
• Discovered a way to decrease snapshot restore size by 6.42-13.04× for simple serverless functions across the evaluated runtimes by sharing read-only library pages across functions, significantly reducing the critical path for cold starts
• Evaluated the feasibility of specialized hardware acceleration for decompressing a subset of program's pages at snapshot restore

### Software Engineer Intern @ Microsoft
Jan 2023 – Jan 2023 | Redmond, Washington, United States
Windows Security @ Microsoft Offensive Research & Security Engineering (MORSE)
• Discovered and investigated two critical heap-overflow remote code execution vulnerabilities as a result of fuzzing, which were later disclosed and published as CVE-2024-20696 and CVE-2024-20697 marked with "Important" severity level (credited to MORSE)
• Improved the fuzzing coverage by 83% for RAR5, 74% for RAR and 61% for 7-Zip in open-source library libarchive, used in the release of native support of additional archive formats in Windows 11

### Software Engineer Intern @ Microsoft
Jan 2022 – Jan 2022 | Redmond, Washington, United States
Security Research @ Microsoft Defender for Endpoint
• Built a synchronizer that stores the ongoing logon and remote desktop events into a graph of historical network activity, used as a foundation for lateral movement detections

### Software Engineer Intern @ Microsoft
Jan 2021 – Jan 2021
Explore Program – Microsoft 365 Substrate
• Collaborated to build a command line tool for querying distributed service mappings to accelerate the investigation time by over 100% for related on-call escalations and availability incidents
