Automate infrastructure provisioning, monitoring, and reporting using tools like Terraform, Kubernetes, and cloud-native solutions.

Strong ability to analyze large datasets, identify cost inefficiencies, and present data through dashboards and visualizations.
Proven experience in cloud cost management, FinOps practices, and scalable architecture design.
Proficiency in traversing and analyzing large datasets, with expertise in tools like SQL, Python, or other data processing, query languages.
Expertise in developing dashboards and visualizations using tools like AWS Quicksight, Tableau, Power BI, or cloud-native solutions (e.g Kubecost/Opencost)
Strong knowledge of cloud platforms (AWS, Azure, GCP), infrastructure-as-code (Terraform, Kubernetes), and automation frameworks.
Experience in system and application design with a focus on efficiency and reliability.
A broad technical background with experience across development and infrastructure tools.
Excellent communication skills, capable of conveying complex technical and financial concepts clearly.
Passion for driving system efficiency, cost-effectiveness, and performance improvements.
Strong financial modeling and budgeting skills.
Certification in AWS, Azure, or GCP is a plus.
