PROFILE
Mikhail Yankelevich
Mikhail Yankelevich contributed to the JetBrainsRuntime repository by modernizing test infrastructure and improving encoding robustness over a two-month period. He migrated PEM and validator tests from shell scripts to Java, integrating JTReg runnable UI for password tests to streamline automation and maintenance. Addressing test fragility, he implemented explicit UTF-16 and ISO-8859-1 encoding handling and standardized HEX dumps, enhancing portability and reliability across environments. Mikhail also resolved a certificate validity path issue in the ConciseJarsigner test and performed maintenance by removing obsolete entries. His work leveraged Java, shell scripting, and security expertise to deliver more stable and maintainable test suites.
