Summary
🤩
Rockstar🎓
Top SchoolAtharva Nimbalkar is a Protocol Engineer with 7 years of experience building scalable Web3 infrastructure, currently focused on scaling Ethereum and contributing to EVM autoscaling projects. He has held engineering roles at Conduit, Shardeum Foundation and Nethermind, where he shipped protocol-level features, staking/rewards logic, and production tooling. A systems-minded backend developer, Atharva has implemented low-level SIMD support (NEON, SSE2, WASM) and contributed to widely used open-source projects that bridge performance and portability. He pairs a strong academic foundation from IIIT Nagpur and Boston University with practical experience in blockchain node software, CLI/GUI integration, and edge-case protocol robustness. Outside work he combines programming with design, writing and piano, hinting at a multidisciplinary approach to problem solving.

Implementations of SIMD instruction sets for systems which don't natively support them.
Role in this project:Back-end Developer
Back-end DeveloperContributions:10 reviews, 87 commits, 30 PRs in 5 months
Contributions summary:Atharva implemented initial implementations of various SIMD (Single Instruction, Multiple Data) instruction sets for systems that don't natively support them, primarily focusing on NEON for ARM architecture. Their commits involve writing test code to verify the correctness of these implementations, specifically for floating-point operations and integer arithmetic. The user also added SSE2 and WASM implementations for BCax.h, demonstrating skills in broader SIMD support.
