Это 4-недельный курс о том, как проектировать системы, как новые (чтобы потом не переделывать), так и старые (чтобы разобрать на части и ускорить разработку); как распиливать монолиты, обоснованно выбирать технологии и архитектурные стили, оставляя после себя понятную документацию. DDD, EventSourcing, Микросервисы и т.д., все эти модные слова будут частью этого курса.
