PROFILE

Rnovikov

Worked on the neonlabsorg/neon-evm repository, delivering five features over four months focused on performance, reliability, and maintainability. Developed ProgramData and build configuration caching to reduce data fetch latency and accelerate builds, leveraging Rust and Solana SDK for efficient system integration. Refactored the RPC interface to support account data slicing and modularized the RPC client for singledb version integration, improving error handling and data-driven accuracy. Enhanced EVM loader reliability by refining slot retrieval, error logging, and cache management. Emphasized robust testing and code cleanups throughout, ensuring scalable data access and smoother Neon EVM version migrations without introducing new bugs.
