Summary

Rockstar🎓
Top SchoolYaroslav Yashin is a software engineer with 10 years of experience specializing in high-performance systems, ML infrastructure, and blockchain tooling, now based in Haifa. He has built GPU-accelerated cryptographic pipelines and Cargo–Metal build tooling at the Ethereum Foundation, engineered CUDA and MoE optimizations and LoRA DPO fine-tuning for large models at RedLab, and led performance-focused Web3 iOS SDK work including a Rust SMT solver integration. Comfortable across Rust, C++, Python, Swift and CUDA/Metal, he turns research "future work" into production-grade implementations and CI-driven benchmarks that speak for themselves. He combines low-level systems thinking (lock-free ring buffers, custom kernels) with applied ML and LLM tooling (RAG with FAISS, LangChain), keeping latency and throughput as first-class citizens. An active open-source contributor—author of the OpenAI Sublime Text plugin and contributor to web3swift—he also automates build and profiling workflows to shave weeks off integration time. Colleagues describe him as the engineer who reads the newest ZK/ML paper over coffee and ships the runnable, optimized version before most teams finish the literature review.
