Hi, I'm Simone —
I build systems
that hold under
pressure.
I design pipelines and ML systems built to scale. Occasionally, I ship side projects that solve real problems.
Selected work
Featured Projects
Real-Time Event Pipeline
Legacy batch pipeline couldn't handle peak traffic spikes, causing 4-6 hour data delays in downstream ML models.
→ Handled 12M+ events/day
→ Reduced end-to-end latency from 4h to 90s
ML Feature Store
Data science teams were duplicating feature engineering logic across 8+ models, causing inconsistencies and wasted compute.
→ Reduced feature computation time by 63%
→ Unified 40+ features across 8 models
Data Warehouse Migration
Migrating a 10TB legacy Redshift warehouse to Snowflake with zero downtime and full historical parity.
→ Migrated 10TB+ data with zero data loss
→ Reduced query costs by 41%

Apps & MVPs
Alongside the day job, I build micro-products — mostly data tooling and developer utilities. Some stay experiments; some ship.

Writing
System design breakdowns, data modeling decisions, performance tuning, and lessons learned building infrastructure at scale. First posts in progress.
