Lokomot worked on compiler and IDE infrastructure, focusing on bug fixes that improved language interoperability and code analysis. In the dotty-staging/dotty repository, he addressed a Java parsing edge case in the Scala 3 compiler, aligning annotation handling in array types with Java syntax to reduce compilation failures and enhance reliability. Later, in JetBrains/intellij-scala, he refined the ModifierChecker logic for top-level Scala declarations, ensuring correct application of the final modifier and adding regression tests for stability. His work demonstrated depth in Java and Scala parsing, compiler development, and IDE plugin engineering, contributing to more robust language tooling and test coverage.
