Education

• Master in Computer Science Fundamentals (M2), Ecole Normale Supérieure de Lyon, France
  2021 – 2022
  Relevant Courses: Compilation and Program Analysis, Distributed Systems, Parallel and Distributed Algorithms and Programs.

• Master of Engineering in Computer Science, National Advanced School of Engineering of Yaounde, Cameroon
  2016 – 2021
  Relevant Courses: Probability and Statistics, Data Structure and Algorithms, Theory of Compilation, Linear Algebra, C Programming, Cloud Computing and Virtualization.

Experience

• PhD. Thesis in Computer Science, Université Grenoble Alpes (UGA) | Orange Innovation, France
  2023 – 2027 (expected defense: April 2027)
  Description: Designed and developed GOODKIT, a novel Live VM Introspection framework written in Rust and C to leverage co-located side-VMs for native-speed target access and strong isolation. Implemented fine-grained, lock-aware memory coherence mechanisms and kernel probing subsystems within the Firecracker VMM and the Linux kernel, bridging the gap between secure monitoring and production cloud performance.

• Research Engineer
  2022
  N7 Institut de Recherche Informatique de Toulouse (INP Toulouse)
  Optimized the paravirtualization layer for UPMEM PIM hardware by implementing an I/O request batching system and a custom prefetch cache, drastically reducing VM-exits on read operations. Parallelized request handling within the Firecracker VMM to enhance overall throughput and reduce latency.
  Duration: 3 months.

• Research Intern
  2022
  Laboratoire de l’Informatique du Parallélisme (LIP) of the ENS de Lyon
  Researched and implemented the paravirtualization layer for UPMEM PIM (Processing-In-Memory) hardware. Built the prototype using Amazon’s Firecracker and VirtIO interfaces to bridge low-level accelerators with virtualized environments.
  Duration: 6 months.

• Research Intern
  2021
  Laboratoire de l’Informatique du Parallélisme (LIP) of the ENS de Lyon
  Improved the performance of a distributed hypervisor based on QEMU/KVM for the Scalevisor project, aiming to build distributed virtual machines.
  Duration: 7 months.

• Research Intern with Alain TCHANA
  2020
  École Normale Supérieure de Lyon
  Implemented the write-update protocol to optimize updates propagation in the distributed hypervisor GiantVM.
  Duration: 2 months.

• Intern at Megasoft LLC, Yaounde, Cameroon
  2019
  Implemented a mechanism for uploading/downloading large files securely to/from the company’s server.
  Duration: 2 months.

Grants
