I am a self managed, problem solver, highly organized and a proactive communicator. I would like to work on the latest technologies and resolving complex technical problems. I Also like to design and architect efficient CICD solutions.
I was always a good team player when I worked in teams for several projects. However, Last couple of years I worked remotely and independently and enjoyed a lot. Being a DevOps and Solutions Architect, DevOps always fascinates me due to the complex problems and challenges it brings and I love to solve them. It would be a great experience to work with you.
Thanks
