Experienced DevOps Engineer with a passion for security and automation.
What I'm looking for
I am a Senior DevOps Engineer with over 10 years of expertise in Platform Engineering and Site Reliability Engineering (SRE). My career has been dedicated to integrating security at every stage of development, automating CI/CD pipelines, and implementing secure Infrastructure as Code (IaC). I have extensive experience with Kubernetes, orchestrating scalable and resilient containerized workloads while optimizing cluster performance and enforcing security best practices.
Throughout my career, I have demonstrated a proven ability to build internal developer platforms, enhance system reliability, and automate incident response. My work has led to significant cost reductions and operational efficiencies, such as a 37% decrease in FinOps costs during a recent migration to a serverless architecture. I am passionate about fostering a security-first culture and driving innovation in fast-paced environments, making me a strong communicator and collaborative team player.
