Mikhail Yankelevich
Contributed to JetBrainsRuntime by modernizing test infrastructure and enhancing encoding robustness over a two-month period. Migrated PEM and validator tests from shell scripts to Java, integrating JTReg runnable UI for password tests to streamline automation and improve maintainability. Addressed test fragility by adding explicit UTF-16 and ISO-8859-1 encoding handling, and standardized HEX dumps for consistent output. Improved test reliability by fixing certificate validity path failures and cleaning up obsolete problem list entries, which accelerated CI feedback and reduced maintenance overhead. Leveraged skills in Java, shell scripting, and security to deliver more portable, maintainable, and robust testing for runtime changes.
