ArmeniaWhat I'm looking for
I am a Senior Backend Engineer with 10+ years building scalable, high-performance systems across Node.js, Rust, and Python, focused on distributed architectures, cloud-native infrastructure (AWS/GCP), messaging systems, and database design. I have led multiple backend projects from architecture through production, delivering performant systems for Web3, streaming, cloud services, and embedded platforms.
My achievements include building a Solana validator plugin in Rust, creating high-performance Node.js native modules in C++, designing serverless AWS infrastructure with Pulumi, and leading cross-functional teams to deliver end-to-end products. I prioritize clear system design, performance optimization, and mentoring engineering teams to produce reliable, production-grade software.
