Security Software Engineer at Avito

Summary
👤
SeniorKonstantin Tretyakov is a Security Software Engineer in Moscow with 16 years in IT and four years specializing in software and SRE work. He blends Go, Python, and Rust to build efficient, production-ready security and data infrastructure rather than forcing tools to fit tasks. At Avito and prior roles he introduced SRE practices, CI/CD, and automation that cut pipeline times from ~90 to under 5 minutes, reduced failures dramatically, and reclaimed terabytes of storage and significant compute resources. He has hands-on experience delivering 99.99% uptime e-commerce platforms, canary deployments, and automated recovery for inaccessible client infrastructure. An active contributor to open-source—improving a self-balancing interval tree library—he brings both systems-level rigor and a pragmatic engineering mindset. Notably, his work often focuses on squeezing operational inefficiency out of legacy data stacks while keeping systems auditable and resilient.
