Senior🎓
Top SchoolNikita Kryuchkov is an IT leader with nine years of hands-on software engineering and team leadership experience, currently heading technology at SberEducation in Saint Petersburg. He combines a strong C#/.NET backend background with modern JavaScript front-end expertise, having led teams at Luxoft and delivered full-stack systems across finance, education, and microservice architectures. An active open-source contributor, he has improved document-processing in the popular unioffice Go library and hardened consensus and testing in the go-spacemesh protocol implementation, demonstrating comfort across languages and distributed systems. Known for shipping reliable features and stabilizing complex codebases, he often focuses on testability, tooling (Prometheus metrics), and pragmatic refactors that reduce technical debt. He also brings an unusual mix of product-facing CLI and storage work from blockchain and wallet projects to traditional enterprise systems, bridging low-level reliability with user-facing features.
