Tommaso Bersani

I’m a Cloud Architect and data/software engineer specializing in AWS serverless architectures and Infrastructure as Code with Terraform. I bring a strong foundation from a Master’s in Computer Engineering (110/110 cum laude) and 5+ years of hands-on delivery across cloud, data engineering, and backend systems.

At Storm Reply, I architected and deployed high-scale ETL/ELT data pipelines for a major Italian public entity using AWS Glue (PySpark) and Redshift within a medallion lake architecture. I streamlined workflow orchestration with AWS Step Functions, integrating dbt and Apache Airflow, and enabled streaming ingestion through Kinesis.

I also build production-grade serverless backends and microservices with FastAPI, NestJS, and AWS Lambda—decoupled via SQS/SNS and DynamoDB. With Terraform and Terragrunt, I automate environments and manage ECS/Fargate deployments through robust GitHub Actions CI/CD pipelines, while optimizing security and observability with CloudWatch and KMS to reduce operational expenditure by 60%.

Previously, at PwC I supported digital transformation roadmaps and cloud governance using AWS Well-Architected standards and FinOps. Earlier roles include Full Stack development at NS12 and end-to-end freelance delivery (Next.js/Tailwind, Supabase/Firebase, Stripe integrations), including an OpenAI API-powered chatbot that reduced manual support load.
