Rockstar🎓
Top SchoolOleg Iakushkin is a Senior Software Engineer and UK Global Talent Visa holder with 13 years of experience designing high-performance distributed systems, blockchain clients, and AI/ML solutions. He blends deep academic rigor—a PhD-equivalent in distributed systems and 50+ Scopus publications—with hands-on engineering in C++, C#, Python, Rust and Go across production and research projects. Oleg has contributed to Nethermind’s Ethereum client, improving block production and consensus metrics, and now works on blockchain infrastructure at Chainlink Labs. He has a track record of building deployable AI pipelines, emulated local blockchain environments for debugging, and shipping research-grade ML models (H100 training, FAISS-based vector DBs). Comfortable leading teams and presenting at conferences, he also brings less obvious strengths: formal modeling expertise (Petri nets) applied to consensus research and a history of turning complex academic work into production systems.
