Freelance Solution Architect

Cloud, Data &
AI Architecture
for complex systems.

I help data-intensive companies — telcos, fintechs, SaaS platforms — design and build intelligent, scalable data infrastructure and agentic AI pipelines. About 10 years in IT, the last 4–5 as an architect.

About

Architect at the intersection of data and intelligence.

I'm Davide, a freelance Cloud, Data & AI Architect with nearly 10 years in IT and 4–5 years as an architect — designing and delivering data-intensive systems from large-scale Hadoop migrations to real-time streaming architectures and agentic AI pipelines.

My background spans Cloudera/Hadoop environments, AWS data platforms, real-time streaming with Kafka and Redpanda, and the emerging world of agentic AI — combining LLMs, vector databases, and orchestration frameworks into production-ready solutions.

I work with companies that treat data as a core asset and need an architect who can bridge the gap between infrastructure and intelligence — someone who has built both sides from scratch.

Selected work

Real projects, anonymised. The complexity is real.

Financial Services
Italian Bank
Cloudera CDP Migration for a Banking Group
Led the end-to-end architecture and delivery of a Cloudera CDP migration for one of Italy's largest banking groups. Designed the target-state data platform, managed workload migration across HDFS, Hive, and Spark environments, and ensured regulatory compliance throughout the transition with zero data loss.
→ Zero-downtime migration → Full regulatory compliance → Significant infra cost reduction
Advertising & Media
Large Ad-Tech Company
AWS Big Data Platform for Advertising Analytics
Designed and delivered a scalable AWS-native big data platform for a major advertising company processing billions of ad events daily. Built ingestion pipelines, a data lakehouse on S3, and real-time analytics dashboards enabling campaign performance monitoring at scale across multiple markets.
→ Billions of events/day → Sub-second query latency → Multi-market deployment
