I’m Alex, a principal software engineer based in Cluj-Napoca, Romania. For over a dozen years I’ve worked on large backend systems in Java, Kafka, Couchbase and Go, most of it around a high-traffic promotions platform that hundreds of engineers contribute to.
I also created wro4j, an open source web resource optimizer for Java.
What I write about
- Design decisions that look small and turn out to be load-bearing
- Concurrency, caching and what breaks in production
- Working with AI tools without giving up ownership of the result
