Throughout my career, I have successfully implemented database software upgrades, managed high availability configurations, and ensured data integrity in demanding environments. I am well-versed in security measures, including authentication, authorization, and auditing, and have achieved a high score on database CIS benchmarks.

I am a certified professional with a strong educational background in Computer Technology and various certifications in database administration, cloud infrastructure, and software development. I am a team player with excellent critical thinking, problem-solving, and communication skills, and I am committed to delivering high-quality results in fast-paced environments.
