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.

Projects

Payment Risk / Pulse

• Built a Java/Flink reference pipeline for synthetic Kafka payments with event-time ordering, deduplication, stateful risk rules, and transactional output; added ClickHouse analytics and a React/TypeScript dashboard for explainable decisions and pipeline health.

Marketplace Lakehouse

• Built a local Kafka/Spark Structured Streaming lakehouse with Iceberg, Trino, SCD Type 2, and data-quality gates; added a TypeScript dashboard, Airflow orchestration, and Prometheus/Grafana monitoring.

Milano Mobility

• Built a Python/PostgreSQL/dbt/MinIO pipeline with versioned archives and tested historical models; added a TypeScript/MapLibre commute explorer and timetable-aware routing API.

Universe Visualizer

• Built a JavaScript/Three.js atlas integrating NASA and Gaia DR3 catalogues, with WebXR virtual and mixed reality, automated tests, and GitHub Actions deployment.

Kamisado

• Built a TypeScript/Node.js/Socket.IO multiplayer game and Electron host with server-authoritative rules, reconnection, and automated rule and socket integration tests.

STM32 Microphone Recorder

• Built C firmware for MEMS microphone capture using DFSDM/DMA and a Python receiver for 16 kHz WAV audio over ST-LINK USB, with buffering, checksums, and host tests.

Interactive Physics Simulations

• Implemented research-based Three.js fluid simulations and Python/Manim animations, with numerical tests for conservation laws, analytical limits, and stopping behavior.
