## Work Experience

### Big Data Engineer - Enel

Jul 2022 - Present

- Build and maintain pipelines for medium- and low-voltage grid measurements using Apache Spark and Kafka, supporting downstream energy-grid analysis.
- Led a migration from Cloudera Distribution Hadoop (CDH) to Cloudera Data Platform (CDP), modernizing the distributed data infrastructure.
- Develop and tune Spark ETL workloads and Apache NiFi ingestion flows; benchmark Apache Iceberg with Spark and Flink.
- Implemented custom equality-delete file commits in Spark workloads using Apache Iceberg.
- Optimize MongoDB Atlas indexes, memory usage, and autoscaling; integrate Redis caching through Redisson in Spark jobs.
- Build Java/Kotlin microservices with Spring Boot to expose MongoDB data through APIs.
- Automate S3 Parquet merge, deduplication, backup, and restore operations with Python, and Kafka/S3 checks with Bash.
- Built a Go desktop tool with Fyne to automate Excel processing, data filtering, and report generation.
