Senior🎓
Top SchoolKirill Kovalchuk is a Senior Software Engineer based in Sydney with 11+ years building high-performance backend systems and tooling across startups and large product teams. He specializes in performance optimization, scalability and observability—turning slow systems fast and tracing down elusive bottlenecks and bugs while automating tests and routine workflows. His experience spans high-load consumer platforms (millions of daily users and multi-GB/sec traffic) to workforce management and streaming ingest systems, and he’s comfortable across PHP, Node.js, Docker and Kubernetes ecosystems. A pragmatic engineer who champions SOLID/DRY/KISS principles, he pairs hands-on coding with mentoring and interview-level technical leadership. Less obvious: he combines deep production performance instincts with a developer-first automation mindset that keeps teams shipping reliably.
