Hi there. I'm Bartek and I specialize in JVM languages, mainly Scala and Kotlin.
I am the author of the blog.
You can check out the libraries I've made:
- M&DE - Mirror Annotations & Default Extraction. A Scala 3 macro library that extends
scala.deriving.Mirrorwith annotation metadata, default values, generated members, and transparent wrapper support. - Alpaca - A type-safe lexer and parser library for Scala 3, featuring compile-time validation and a pattern-matching DSL.
- mcodec - GenCodec-style serialization for Scala 3 — a format-agnostic, streaming Input/Output core with type class derivation built on
M&DE. - justworks - A Gradle plugin that just works and generates type-safe Kotlin Ktor clients from OpenAPI specs
- sure - Type-safe value validation DSL for Kotlin Multiplatform.
