Summary
I am a highly skilled, motivated and dependable individual seeking a challenging position to utilize my skills as well as try new ideas and new technologies. I have over 5 years of experience working as a Cloud and DevOps engineer during which I have been able to accumulate extensive hands-on experience in supporting, automating, and optimizing application deployments in AWS by building an automated CI/CD pipeline without forgoing security and performance. I have led and worked on multiple projects through the SDLC.
I am very detail-oriented when it comes to spotting anomalies and have excellent communication, problem-solving, and decision-making skills and always ready to try new tools/technologies to improve performance and simplify deployments.
