Hello! I'm Bazlur, a Software Engineer with over a decade of professional experience in the software industry, primarily focused on Java and related technologies. I was recently honored with the title of Java Champion.

Beyond my regular work, I am passionate about mentoring, writing, speaking at conferences, and contributing to open-source projects. I founded and currently moderate the Java User Group in Bangladesh, organizing meetups and conferences to share Java-related knowledge with the community since 2013. I was named a Most Valuable Blogger (MVP) by DZone, one of the world's most recognized technology publishers. Additionally, I serve as an editor for the Java Queue at InfoQ, another leading technology content publisher and conference organizer, and at Foojay.io, a platform for OpenJDK enthusiasts. I have also published five bestselling books about the Java programming language in Bengali.

I am currently writing a new book with O'Reilly titled "Modern Concurrency in Java."

I hold a bachelor's degree in Information Technology, majoring in Software Engineering, from the Institute of Information Technology, University of Dhaka, Bangladesh. I currently reside in Toronto, Canada.

Modern Concurrency in Java is now available on O'Reilly Media! 🎉 Read it on O'Reilly
