What I'm looking for

Looking for a challenging role in cloud engineering

I am a self-motivated and hard-working engineer with extensive experience in cloud infrastructure, distributed systems, and tools that increase product availability, observability, and quality. I have a strong background in collaborating with cross-continent teams and am sensitive to different cultures.

I have led efforts towards modernizing infrastructure and deployment strategies, completely automating deployment pipelines using technologies like Kubernetes, Helm, and Flux. I have also reduced cloud infrastructure spend by optimizing resource utilization and resizing/eliminating resources.

I am a strong problem solver, able to break down complex tasks and drive them to completion. I continuously challenge the way things are and find ways to improve them, taking responsibility for personal development in technical and non-technical skills.
