Worked on core infrastructure for getsentry/relay and getsentry/symbolicator, focusing on performance and compatibility improvements. In getsentry/relay, delivered a memory- and performance-optimized data structure by refactoring DataCategories from an array to a bitfield, enabling faster and more efficient category matching for scalable quota checks. For getsentry/symbolicator, expanded ARM64 Windows crash symbolication by upgrading the symbolic dependency to support Arm64 PE unwinding, improving the accuracy and reliability of crash reports. Leveraged Rust for system programming, data structures, and dependency management, demonstrating a focus on maintainable, high-throughput solutions that address both backend efficiency and platform compatibility requirements.
