Investigate unusual access to a private dashboard at a manufacturing firm. The findings underscore the importance of monitoring internal traffic patterns for signs of scripted abuse or insider threats.

Skills

Cloud

Cloud computing enables organizations to deploy systems and applications with minimal upfront infrastructure, scale resources on demand, and operate globally. Cost management and optimization are critical considerations for maintaining an efficient cloud-native workflow.

Identity Management & SSO

Identity management ensures the right individuals have appropriate access to technology resources. Single sign-on (SSO) enhances user experience and security by allowing users to authenticate once and access multiple systems seamlessly.

Security & Access Control

Security and access control involve defining and enforcing who can access systems, data, and resources. By applying principles like least privilege and role-based access, organizations minimize the risk of unauthorized access or data breaches.

DevOps & Automation

PCollaboration and automation are the cornerstones of DevOps, enabling faster and more reliable releases through CI/CD pipelines, Infrastructure as Code, and scripting. These practices create scalable workflows that accelerate innovation and enhance service stability.

Monitoring & Observability

Monitoring tracks system health and performance through metrics, logs, and alerts. Observability goes deeper – giving you insight into internal states by analyzing telemetry data. Together, they help detect issues early, troubleshoot efficiently, and optimize performance across infrastructure and applications.

Analytics & Business Intelligence

Without clear analytics and stakeholder alignment, data is just noise. Analytical and BI thinking turns raw information into insight, while collaboration ensures those insights actually drive meaningful business decisions.
