PROFILE
Jonas Stahl
Jonas Stahl enhanced the JetBrains/intellij-scala repository by developing and refining structural search capabilities for Scala, focusing on both Scala 2 and 3 language support. Over four months, he delivered features that expanded pattern matching, improved code analysis accuracy, and enabled robust refactoring workflows. His work included core engine improvements, integration with the IntelliJ Platform SDK, and the addition of support for advanced Scala constructs such as given instances and export statements. Using Scala and XML, Jonas applied techniques in code parsing, static analysis, and plugin development, resulting in deeper language coverage and more reliable tooling for large-scale codebases.
