My name is Sobhan Saghaye Polkoo. I am 37 years old and I’ve spent much of my professional life focusing on database system and software engineer fields. I got my bachelor degree in software engineer in 2010. And recently I got my master degree in SE in 2023 with GPA ~3.9/4. My professional experiences, I work on SQL server and IBM DB2. Work on IBM DB2 is more challenging and difficult. Working with live and massive data, managing and maintaining objects, backup and recovery, optimizing operations, query optimizing and all.
