Summary
👤
Senior🎓
Top SchoolKonstantin Mikhliuk is a Senior Software Engineer based in Old Toronto with a decade of professional experience and eight years focused on architecting and scaling backend systems. He specializes in modernizing large Ruby codebases and multi-threaded JRuby services, having led a DRY/SOLID-driven restructuring of a 600k LOC monolith and introduced RBS typing to reach 30% coverage. Konstantin pairs practical performance engineering with pragmatic tooling choices—rewriting an Elasticsearch client to halve response times, cutting a data job from 8 hours to 10 minutes, and migrating infrastructure to ECS with 12-factor practices. He has strong hands-on experience across data stores (Postgres, ClickHouse, Redis), messaging (RabbitMQ, Kafka), and AWS, and has driven cross-team delivery and documentation that materially improved product understanding. Notably, he balances deep systems work with developer enablement—creating automation that saves teams hours weekly and authoring widely used Confluence guides.
