About Me

I’m a Cloud & DevOps Engineer passionate about building secure, scalable, and high-performance solutions on AWS, Azure, and Google Cloud.

With hands-on experience in cloud security, infrastructure automation, and system optimization, I bridge the gap between innovation and reliability. Before tech, I served as a licensed Dental Therapist with a certification in Public Health, where precision, compliance, and empathy were non-negotiable. Today, I bring those same principles to every cloud architecture project, delivering results that make a real impact.
