Summary
👤
Senior🎓
Top SchoolDenis Kayshev is a backend engineer with eight years of experience building and optimizing production services, currently focused on serving large language models at Avito. He has strong expertise in Rust and Python, modern async ecosystems (actix, tokio, asyncio), and relational databases, having led PostgreSQL migrations and async rewrites at RAMBLER&Co. Denis consistently improves developer velocity and reliability—examples include speeding CI/CD pipelines 2.5–3x and creating cross-platform build jobs for macOS wheels. He also writes tooling and libraries, such as a Draft.js-to-HTML converter, and has experience deploying distributed pipelines, Redis, RabbitMQ, Docker and Kubernetes. As a former lecturer and code reviewer, he pairs hands-on engineering with teaching and process design, which surfaces in his pragmatic approach to code quality and maintainability. Based in Moscow, he brings a blend of low-level systems thinking and practical product delivery that often surfaces in performance and migration projects.
