About Me

Hello and welcome to my corner of the World Wide Web!

I am a Software Developer at Tich Apps Development. I mostly live in the JVM world, writing Java and Scala code that handles real data, streams and events.

I enjoy building event-driven systems with Kafka and SSE, keeping things simple and typed with ZIO and tapir, scratching pixels with libGDX and Swing, building Android apps with Kotlin and Jetpack Compose, and occasionally hanging out in Go.
