Charles Alivanera is a Data Operations Engineer and Infrastructure Specialist focused on Cloud Architecture, ETL Pipelines, and Identity Access Management (IAM). Currently the Support Technician at Aetion, he orchestrates secure data infrastructure for over 50 enterprise clients, including the FDA, EMA, and top-tier pharmaceutical firms. He architected global Role-Based Access Control (RBAC) policies using AWS Cognito to ensure SOC 2 compliance for users and deploys custom Python and R scripts to automate the lifecycle of TB-scale sensitive files via AWS S3, enabling compliant patient tokenization and secure data linkage.
He excels at transforming manual operations into scalable engineering solutions. Charles recently spearheaded a critical enterprise ETL Migration, transitioning global support operations from Zendesk to Salesforce Service Cloud with 100% data integrity. This initiative required complex SQL schema mapping to migrate over 250,000 legacy records. Previously at VXI, he demonstrated significant business impact by engineering a predictive churn model in R that safeguarded $4M in annualized revenue and building a proprietary BI framework that drove a 22% increase in cross-sell conversion rates.
Beyond technical execution, Charles is a proven leader who co-managed the 2023 Metro Manila Pride March (~29,000 attendees), designing its post-event data evaluation framework. A Certified Associate Data Engineer (DataCamp) and Google Data Analytics Professional, his technical stack includes Python, SQL, R, AWS (S3, EC2, Lambda), Snowflake, Spark, Airflow, Docker, Kubernetes, and Grafana. He is actively seeking Data Engineering roles that demand infrastructure scalability and rigorous analytical problem-solving.
