Hi! My name is Ruslan.
I worked as a chief engineer (Big Data) at Sberbank of Russia, where I managed and supported 120 Hadoop clusters, developed Bash scripts for task automation, implemented security policies using Apache Ranger and IPA, and collaborated with development teams to integrate applications with the Hadoop cluster.
I also have experience working as a system engineer at CROC Inc., where I administered Linux servers, supported virtualization (VMware, Hyper-V), and Windows ecosystem (Windows Server/Active Directory/Exchange).
Currently, I am located in Istanbul and open to remote work or relocation opportunities.
