Summary
👤
Senior🎓
Top SchoolOleksiy Chechel is a Senior Technical Lead with over a decade of experience designing and delivering high-load, multi-component systems using Golang, NodeJS, C/C++, and rich web technologies. He combines hands-on coding (including low-level TCP/HTTP, multi-threading, and database optimizations for MongoDB and ClickHouse) with leadership—having trained 20+ Golang developers and led engineering teams as CTO. Known for shipping production-grade microservices, websocket-heavy UIs, and developer tooling (many open-source libraries on GitHub), he also tackles non-obvious problems by diving deep into complex codebases. His practical background spans security research, containerized deployments, and large-scale data migrations, reflecting a blend of systems thinking and product-focused delivery. Based in Calgary, he brings a rare mix of backend performance expertise and frontend/UX awareness, often building cross-platform components and tooling that accelerate teams.
