Arkency developer (referred to in talks as 'Pavel'/'Pavo'). Maintainer and regular releaser of rails_event_store for over five years. His career is based around legacy software — 'I mostly work on code bases that have accumulated some history' — which he describes as an interesting position from which to introduce rails_event_store. Created the internal 'aggregates' repository structured so that multiple aggregate implementations share one test suite. Co-panelist on the Event-Driven Rails panel at wroclove.rb 2023.
