Senior🎓
Top SchoolIgor Mykhaylyuk is a Senior Full Stack Engineer with 11 years of experience building and modernizing scalable microservice architectures across Node.js, Kafka, SQL/NoSQL databases and containerized deployments. Based in St. Catharines, Ontario, he has a strong record of improving reliability and performance—introducing CI/CD and ESLint, containerizing services to shrink images dramatically, and eliminating timeout and SQL-injection issues through query optimization, Redis caching and security hardening. He routinely drives end-to-end projects from design and OpenAPI documentation to production migration and integration testing, enabling confident upgrades of legacy Node.js stacks. Comfortable across front-end and back-end concerns, he also has hands-on experience recovering broken production data with migrations and syncing complex external systems like Salesforce. Colleagues rely on him for pragmatic architectural diagrams, clear docs and for turning messy legacy systems into well-layered, observable services.
