Hennadiy Hrodskyy

I'm an Amazon Certified Solutions Architect,SysOps Administrator  and Oracle Certified Professional Database Administrator with more than 12 years of experience.

I’ve gone through several different IT roles: systems administrator, analyst, database designer, database administrator, cloud engineer, team leader. This background allows me to understand all aspects involved in application development, being able to design a complex multi platform app from the ground up as well as help troubleshooting an existing app's problems or weird system behaviour.

I find really useful to complete some practice tests before the actual exams. They serve as a last minute refresh and help you identify any weak topic where we need to take a deeper look.

Having said all of this, I invite you to check out my courses here in Udemy and kindly let me know how I can further improve my products. Your constructive feedback is a powerful tool not just to help me, but to also help other people who may have been struggling to learn the subject matter.

Thank you and good luck!
