Hi, I'm Andrei — Backend & Systems Engineer

Rust · Distributed Systems · Blockchain Infrastructure · AI Backend

I build high-performance backend and protocol infrastructure, with a focus on Rust systems programming, deterministic execution, and distributed architectures.

Currently Software Engineer at MultiversX, working on Sovereign Chains and cross-chain execution infrastructure.

• Primary owner of mx-sovereign-sc (>90% of the codebase)
• Designed protocol systems for multi-phase chain deployment and cross-chain execution
• Built testing infrastructure with >90% coverage
• Focus on correctness, performance, and deterministic execution
