Professional Experience
Senior Advisor DevOps Engineer
May 2022 – Present
When I thought I’ve learned every corner of IT – servers, computers, cloud, cybersecurity, development, and so much more, I was wrong. I never thought I’d be into something that is unknown to me. Rio Tinto gave me an opportunity I cannot miss, a challenge that requires hard work and perseverance, which leads to a great experience and learning curve. Being in a team that works with several projects at the same time, I have learned to be agile, resilient, and collaborative while implementing organizational standards and technology best practices. Wearing a hat that I never knew I’ll wear; it always reminds me that there is always a room for improvements.

This is it! Another milestone for me! This is my first time to be in a senior role…in a BIG company! A bit overwhelmed, but I’m ready to face new technologies and challenges.
