I’m a senior software engineer and architect with 17 years of experience building and modernizing backend systems across fintech, banking, automotive, telecommunications, and data-intensive platforms. Most of my career has been spent in the JVM ecosystem, particularly Java, Scala and Clojure, working with distributed systems, cloud infrastructure, and the messy reality of legacy software.
