Automation of hardware telemetry, failure detection, and diagnosis for Meta’s internal cloud infrastructure (millions of servers). Designed and led instrumental evolutions of server fleet management systems in a complex and cross-functional (dozens of teams) environment that spans from hardware design details to application-specific user requirements.○ Overhauled Meta’s hardware monitoring system to enhance scalability, efficiency, and enable critical feature development ◦ Conducted sessions to clarify problems and gather requirements, ensuring project ROI ◦ Designed and championed an innovative roadmap to transform a rigid, tightly-coupled system into a modular data-centric architecture with clear APIs and data models ◦ Facilitated development of anticipated features, such as time-series based detection on complex data ◦ Enabled multi-team collaborative development through decoupled and well-scoped components ◦ Defined and managed a multi-half migration plan, guiding engineers and maintaining momentum ◦ Improved system correctness, efficiency, and developer velocity by introducing Rust (over Python)○ Led shifts in engineering practices to increase correctness, velocity, and efficiency to scale on-host tooling at reduced cost ◦ Systematically addressed critical bugs and technical debt, automated standards (lint, format, PEP, gradual typing of large Python codebase, …) ◦ Mentored and educated engineers on many aspects of software design and data modeling through knowledge sharing, demos, design documents and technical reports, and refined methodologies ◦ Fostered a culture of written documentation, strategic prioritization, and accountability

Paris, Paris, Fr

○ Implemented distributed HTTP and OAI-PMH crawlers to gather open-access publications○ Designed a distributed storage system for user files, metadata and documents (>20TB)○ Designed a metadata/document analysis pipeline, with NLP components to extract relevant information○ Designed internal APIs providing the front-end team with a clean way to access said data○ Deployed and managed two small clusters (2 and 9 machines) for the above

○ Re-architectured and refactored existing production software to increase simplicity○ Designed and built a machine learning and graph mining system for spam/fraud detection○ Designed a sensible API in order to feed and query the system○ Built a PHP front-end for external API interactions and documentation (internal framework)

○ Tested machine learning approaches to detect spam/fraud using existing flags/values ○ Implemented a category classifier to reduce internal search traffic required to serve users○ Designed a native PHP extension to interface existing front-end code with the classifier
