ai.bythebay.io Nov 2025, Oakland, full-stack AI conference Scale By the Bay 2019 is held on November 13-15 in sunny Oakland, California, on the shores of Lake Merritt: https://scale.bythebay.io. Join us! ----- Grzegorz has been involved in the Scala development over the years. First as a student at EPFL, later as an employee of Typesafe where he worked on the Scala compiler and tools surrounding it. The compilation speed has been his focus over the years: early on, he spent a summer working with Martin Odersky optimizing scalac, later he worked on redesigning zinc (the incremental compiler for Scala) that led to 10-50x compilation speed improvements on large code bases. After Typesafe, he took over 1 year-long stint as a hobo. Now he lives in San Francisco and works for Stripe.
