Peter Rivera

Senior Advisor, DevOps Engineer | MCSA | MCAAA | Salesforce


Hello World! I am Peter Rivera, though you can address me as Peter or Peejay. Currently, I hold the position of Senior Advisor DevOps Engineer at Rio Tinto. In this role, I focus primarily on DevOps practices, including automation, CI/CD, and providing support for both PaaS and IaaS solutions. My approach to these responsibilities is agile and results oriented.

Educationally, I hold a bachelor’s degree in information technology, having graduated in 2012. During my academic journey, I was honored as a Dean’s Lister and achieved Microsoft Certified Professional status.

Professionally, my career trajectory has been diverse. I began as an IT Support and System Administrator in 2013. Subsequently, I expanded my horizons by working as an IT Engineer at an IT security firm in Singapore. Later, I assumed the role of a system engineer in the financial sector, where I gained extensive experience in server-side technical support and infrastructure management. My most recent position was as a senior IT operations engineer in the manufacturing industry, which provided valuable insights into DevOps tools, processes, and management.

My journey across various industries has equipped me with a wealth of knowledge spanning diverse technologies. From fundamental troubleshooting and programming to intricate infrastructure management, I thrive on continuous learning and growth.

As a technical enthusiast, I approach challenges with a logical mindset and a penchant for automation. I firmly believe that technology empowers us to create remarkable solutions, turning our ideas and concepts into practical realities that enhance our lives.

“The process may seem strange and yet it is very true. I did not so much gain the knowledge of things by the words, as words by the experience I had of things.”
