Stefano Bonetti is an experienced engineering manager and backend engineer with 11 years building large-scale, reactive systems primarily on the JVM. He has deep expertise in Scala and the Akka ecosystem—contributing to Akka, Akka HTTP and the prominent Alpakka integration library—bringing practical improvements like FTP/SFTP file-attributes, append-mode sinks and hardened error handling. At Apple he leads engineering work on massive data analytics platforms, after earlier senior roles designing reactive pipelines at Expedia and identity/back-end systems at Sky. He pairs hands-on implementation skills (Scala, Akka Streams, Kafka, Spark, Cassandra, AWS) with leadership in productionizing resilient distributed systems. A summa cum laude computer engineering graduate, he also speaks and authors community-focused material on stream-driven design and backpressure. Colleagues describe him as a pragmatic engineer-manager who still prefers to solve core infrastructure problems in code rather than slideware.
Alpakka is a Reactive Enterprise Integration library for Java and Scala, based on Reactive Streams and Akka.

Contributions summary:Stefano focused on enhancing the FTP connector within the Alpakka library. Their contributions involved adding the ability to retrieve file attributes (including POSIX permissions) for FTP and SFTP, and implementing an append mode for the `toPath` sink in the Java and Scala DSLs. They also improved error handling and ensured the correct behavior of the sink. These changes expanded the functionality and robustness of the FTP integration capabilities.
