Rockstar🎓
Top SchoolStanislav Ruban is a Compiler QA Engineer with nine years of experience focused on program analysis, verification, and tooling for compilers. He combines research-honed expertise from the Verification or Program Analysis Laboratory and multiple JetBrains internships with production QA work on the widely used Kotlin compiler, contributing diagnostic and regression tests that catch subtle compiler issues like operator overloading and annotation-processing bugs. A summa cum laude computer science graduate, he has hands-on experience building instrumentation for the Java debugger and applying fault-localization techniques to improve fuzzing efficiency. Based in Cyprus, Stanislav blends academic rigor with practical test automation skills, often tackling the kind of corner-case behaviors that are easy to miss but critical for language correctness.
