Since 2005, I have been developing enterprise applications with Java, providing training, offering consultancy services, and sharing my knowledge with the Java community through speaking at events and writing articles whenever I find the time. My training sessions and consultancy services are primarily focused on Java runtimes such as Spring and Quarkus. In the past, I have also conducted training sessions on big data technologies like NoSQL and Hadoop. I'm one of the leaders of JUG İstanbul, one of Turkey's most vibrant Java communities. I have been an organizer or speaker in many events organized by JUG İstanbul. I'm also the author of the book 'Elasticsearch Indexing', published by Packt Publishing. To avoid being among the losers, I strive to improve myself and make sure that no two days are the same for me.
