PROFILE

Ihor Yatsyshyn

Worked on the ita-social-projects/StreetCode and StreetCode_Client repositories, focusing on backend and frontend improvements to enhance data integrity, reliability, and maintainability. Delivered features such as robust term validation, image handling refactoring, and database health check tooling using C#, TypeScript, and SQL. Applied FluentValidation for validator design and implemented comprehensive unit and integration tests to ensure consistent validation logic and prevent regressions. Simplified data models and stabilized test suites by refactoring mocks and addressing flaky tests. These efforts reduced maintenance complexity, improved onboarding, and enabled safer edits, while proactively validating connectivity and data availability across the application stack.
