Top SchoolIlya Siamionau is a Senior Software Engineer with nine years of experience building backend systems in Python and TypeScript, full-stack React + Redux interfaces, and real-time WebRTC-based video/audio platforms. He has a strong track record in developer tools and IDE integrations—authoring plugins for IntelliJ, VS Code and others that reached thousands of developers—and led the design of a Model Context Protocol server to bridge AI-powered IDEs with product workflows. At Cycode he improved test coverage from 43% to 70%, sped local file handling by 12%, and redesigned a CLI shipped via package managers and binaries; at Abelana he built a cross-platform WebRTC SDK and a multi-component MDM for VR headsets. He maintains high-impact open-source SDKs with over 500K monthly downloads and has implemented C++ and Rust bindings for Python, reflecting a systems-level fluency beyond typical web development. Comfortable shipping end-to-end solutions—from async Django Channels backends and secure Android agents to Electron setup tools—he combines pragmatism with attention to developer experience. Based in Warsaw, he blends production-grade engineering with open-source contribution and a knack for integrating complex systems into usable tooling.
