Eman Čičkušić | Cloud & Data Engineer

Mission: To build and automate production-grade, zero-trust cloud infrastructure that is secure, scalable, and cost-efficient by default. I specialize in GCP, Infrastructure-as-Code with Terraform, and serverless architectures.

Engineering Case Studies: From Problem to Production

The following are curated examples of my work, demonstrating my ability to solve complex technical challenges and deliver measurable results.

Case Study Key Metric & Business Impact Technologies Used
Real-Time Serverless Data Pipeline → >60% Reduction in Query Costs
Achieved via BigQuery optimization, saving projected thousands in annual operational spend. Processed 1,000+ events/sec with <2s end-to-end latency.
GCP Terraform Pub/Sub Cloud Functions BigQuery
End-to-End DevSecOps Pipeline → 100% Automated CVE Blocking
Created a zero-trust pipeline that cryptographically signs and validates all container images, automatically preventing vulnerabilities from reaching production.
Cloud Build Binary Authorization Artifact Registry KMS
Zero-Touch GCP CI/CD Framework → -85% Reduction in Deployment Time
Reduced manual deployment processes from over 30 minutes to a fully automated average of 4m 15s, increasing developer velocity and eliminating configuration drift.
