Additional professional experience:
Looking forward to professional experience with
- Back End: C# (.Net, .Net Core, Desktop development with WinForms), Python, Java, ... - but if you want Kotlin, Scala, Ruby, whatever that seriously makes no difference to me.
- Database: SQL (relationale DBMS, e.g. PostgreSQL, MSSQL, Oracle, ...) - but if you want a NoSQL database or whatever that seriously makes no difference to me.
- Front End: Angular, TypeScript, JavaScript, HTML, CSS, JSON, XML, ... - but if you want React, Svelte, Lit, Stencil, whatever that seriously makes no difference to me.
Additional professional experience:

Looking forward to professional experience with
- Spring, Spring Boot

- Ruby (on Rails)
- continuous delivery or deployment (docker, kubernetes).
- using Go or Rust rather than C++.
