PROFILE

Olivier Desenfans

Olivier Desenfans contributed to lambdaclass/cairo-vm by implementing SECP cryptography support, integrating new cryptographic primitives and Starknet OS syscalls directly into the Cairo VM. He expanded the VM’s capabilities by adding Cairo programs for secp operations and automating their inclusion in testing and build pipelines, using Python and Cairo. On aleph-im/pyaleph, he delivered Python 3.13 compatibility, introduced caching for message count queries to optimize database performance, and improved network stability with a peer aging filter. His work also addressed error handling in IPFS file uploads and enhanced local development environments, demonstrating depth in backend development, CI/CD, and Docker.

Month: 2024-12 — Delivered SECP cryptography support in Cairo VM and Starknet OS syscall integration for lambdaclass/cairo-vm. This release introduces SECP-related hints to the Cairo VM, adds Cairo programs for secp operations, and integrates these capabilities into testing and build pipelines, expanding cryptographic primitives available in the VM. No major bugs fixed this month; maintenance and test coverage improvements were performed to ensure stability. Overall impact: enables secure, native SECP operations in Starknet-based workflows, unlocking new use cases and strengthening security posture. Technologies/skills demonstrated: Cairo VM internals, Starknet OS, cryptographic primitives (SECP), test/build automation, CI integration, and collaboration across the repo.
