What I'm looking for

I seek challenging cloud engineering roles focused on scalable, secure Kubernetes platforms, automation, observability, and cross-team collaboration with opportunities for technical leadership.

I am a Senior Cloud & DevOps Engineer with extensive experience designing and operating cloud-native architectures for high-availability data and trading platforms.

I have led end-to-end implementations of Kubernetes (AKS, GKE, on-prem) and CI/CD pipelines (Jenkins, GitLab CI, GitHub Actions), introducing GitOps (ArgoCD) and Infrastructure as Code with Terraform and Ansible to reduce deployment time and MTTR.

My work includes integrating Big Data and orchestration tools (Spark, Airflow, ClickHouse), implementing observability (Prometheus, Grafana, ELK), and enforcing security and compliance (RBAC, secrets management, CyberArk).

I drive cost optimization and governance through FinOps practices, empower teams via training and documentation, and align technical solutions with business needs to deliver resilient, scalable systems.
