Hi, I prepared a presentation about the "Spring Data JPA & Hibernate LifeCycle & Transaction Management in Spring Framework" for the Trendyol Java Guild community. There are also POC applications that you can reach on the last slide of my presentation, developed by using Hexagonal Architecture including all cases that we mentioned during the presentation. Thank you for taking the time to read! #trendyoltech #springboot #springdatajpa #hibernate

Last week I attended NDC Oslo, together with Fatih Kalyon! A full week full of Development, and related, topics and getting in touch with fellow professionals. Which started for me with a 2-day workshop on "Advanced Software Architecture with Residuality Theory" given by Barry O'Reilly, which was both practical and inspiring! Followed by a 3-day Conference with talks by Troy Hunt, Steve Sanderson, Mark Rendle, Dylan Beattie, Scott Hunter and many other! Which provided valuable insights! #NdcOslo #ResidualityTheory
