What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a DevOps Engineer with over 6 years of experience in cloud infrastructure management, system automation, and CI/CD pipeline development. My expertise lies in building scalable, secure, and highly available systems on AWS, Azure, and GCP. I have a proven track record of optimizing system performance and implementing effective monitoring and incident management strategies.

Throughout my career, I have successfully spearheaded AWS cloud migrations, tripled deployment frequencies, and significantly reduced system downtime through containerization and orchestration. My commitment to security compliance has led to a notable decrease in security incidents, and I take pride in my ability to engineer automation scripts that streamline workflows and enhance operational efficiency.

I thrive in Agile environments and enjoy collaborating with cross-functional teams to deliver reliable and cost-efficient solutions. My passion for technology drives me to continuously improve processes and contribute to the success of the organizations I work with.
