Francesco Sacco
Cloud Engineer & Software Engineer
I started my career as a backend developer, but in recent years my curiosity about the cloud led me to steer my path towards AWS, Kubernetes and running cloud and containerised infrastructure. In general, I am fascinated by anything to do with automating and optimising processes.
Clients
I have worked with leading clients in the public and private sectors:
- MEFItalian Ministry of Economy and Finance
- ADMItalian Customs and Monopolies Agency
- MITItalian Ministry of Infrastructure and Transport
- DeAgostini Scuola
- IVECO
- AgIDAgency for Digital Italy
- SogeiIT company of the Italian Ministry of Economy and Finance
- Avvocatura Generale dello StatoItalian State Attorney General's Office
- AdERItalian Revenue Collection Agency
- SOSESoluzioni per il Sistema Economico
At work
I am a cloud engineer: I design and run AWS infrastructure described as code with Terraform, manage containerised workloads on Kubernetes and ship everything to production through CI/CD pipelines.
In my spare time
I also write software and more IaC: backends in Node.js and TypeScript with MongoDB and Redis, apps in Swift, infrastructure with CloudFormation and SAM. I like owning a service end to end, from the template that creates the network to the response that reaches the phone.
SacketCloud is where I do it, on personal and stimulating projects.

The SacketCloud ecosystem
SacketCloud is a set of personal services: messages, passwords, files. Each one runs on privately owned servers, with no ads and no data collected for other purposes.
Each service states what it protects and what it does not: encryption differs from one service to the next, and the description says exactly which kind.
- Privately owned serversThe services run on privately owned servers, not on platforms that live off their users' data.
- Precise promisesEnd-to-end encrypted, zero-knowledge or encrypted at rest: each service says which of the three, without rounding up.
Projects
SacketKeys
A zero-knowledge password manager: the vault is encrypted on the device with a key derived from the master password, which the server never receives.
- Zero-knowledge
- KDF
- Node.js
SacketCloud Drive
A place for photos and files on privately owned servers. Files are encrypted at rest with AES-256-GCM: storage never holds a plaintext file. The key stays on the server.
- AES-256-GCM
- MinIO
- MongoDB
Case studies
Agentic AI and IaC
A case study on agentic AI applied to IaC: a deterministic rule engine analyses CloudFormation, SAM and Terraform templates, with AI only at the edge to discuss findings and propose fixes. Local execution, no automatic deploys: deterministic core, AI at the edge.
