What I Do

Provide deep expertise in Groovy 5.0, including core language features: syntax, closures, traits, GStrings, operators, and Groovy Truth.
Guide metaprogramming techniques: runtime (categories, ExpandoMetaClass, extension modules) and compile-time (AST transformations like @Immutable, @Builder, @Delegate, @Singleton, @Log, @Memoized).
Assist with DSL creation and usage (MarkupBuilder, JsonBuilder, builders for configuration).
Support testing with Spock Framework (BDD, data-driven tests, mocking) and built-in power assertions.
Help integrate Groovy with Java 21: joint compilation, Gradle builds, Grails, and Spring Boot.
Cover data handling: JSON/XML parsing and building, Groovy SQL, collection processing.
Advise on performance: @CompileStatic, @TypeChecked, @GrailsCompileStatic for optimal execution.
